     BACKGROUND 
     Technical Field 
     Aspects of the embodiments relate generally to control networks, and more specifically to systems, methods, and modes for controlling controllable devices in the control network based on audio commands alone, according to an aspect of the embodiments, and in further aspects of the embodiments, controlling the controllable devices of the control network based on audio commands and other sensory information. 
     Background Art 
     Today, there are home control systems that include lighting, shades, environmental controls, security, audio-visual (AV), and other types of sub-systems. In many of the currently available home control systems, the user can turn and off components of such systems (from hereon in referred to as “controllable devices”), for example, lighting products, by a switch, one or more remote control (RC) devices (such as a dedicated RC device, or through some other type of RC device), remotely through network messages (e.g., command and control messages through the internet), and other means, such as speech. 
     In the latter case, users always desire more convenient methods for managing controllable devices, and the advent of speech based control in handheld devices has led to a desire for speech based control of controllable devices. Currently, lights can be turned on and off automatically when a user enters a room via use of a motion sensor. However, the motion sensor can take several minutes after an occupant has left a room to turn off the lights. This leads to wasted energy and frustration. Speech based control can allow a user to (relatively) quickly turn off lights while leaving a room. That is, when speech based control systems work. 
     As those of skill in the art can appreciate, there are several problems with speech based control systems that must be addressed. Among them are inoperativeness, false positives, collocation issues, and privacy issues. In regard to inoperativeness, this is defined by the speech based control system simply failing to respond at all to a proper command. A false positive is when a user does not intend the controllable device to turn off, but it does. This can occur because the speech recognition system misinterprets the recorded audible signal, and incorrectly applies a control, when one was not intended. Collocation issues can arise when two control devices are relatively close to each other, and a command is heard by both, and both or the wrong device acts on the command that was intended for a first control device, but not the second. The privacy issue arises when certain private areas of a home (e.g., the lavatory) are adjacent to other rooms; commands issued in or near that room can be misinterpreted by the system, causing occupants to make possible embarrassing counter-commands. 
     Accordingly, a need has arisen for more precise audible control of a control network and the controllable devices that make up the control network by providing systems, methods, and modes for controlling controllable devices in the control network based on audio commands alone, according to an aspect of the embodiments, and in further aspects of the embodiments, controlling the controllable devices of the control network based on audio commands and other sensory information.

     According to aspects of the embodiments, the one or more controllable devices comprise lighting control device (lighting device)  110 , which can include devices such as a lighting dimmer, and shade control device (shade device)  112 , which can include devices such as a shade motor. It should be understood that the controllable devices are not limited to a dimmer and a shade motor. For example, lighting device  110  can be a switch or a relay panel, and shade device  112  can be a drapery motor or a smart window film. Additionally, those of skill in the art can appreciate that the controllable devices are not limited to lighting control devices and shade control devices. For example, the controllable devices can be: A/V devices  118  that can include one or more of content sources (audio source, video source), content sinks (stereos with speakers, televisions, and the like), video recorders, audio receivers, speakers, projectors, and the like; Lighting devices  110  that can include one or more of lamps, ballasts, light emitting diode (LED) drivers; HVAC devices  120  that can include one or more of thermostats, occupancy sensors, air conditioning units, heating units, filtration systems, fans, humidifiers, and the like; Shading devices  112  that can include one or more of motorized window treatments, dimmable windows, and the like; Security devices  122  that can include one or more of security cameras, monitors, door locks, and the like; Household appliances  124  that can include one or more of refrigerators, ovens, blenders, microwaves, and the like; Control devices  126  that can include one or more of switches, relays, current limiting devices, and the like; and Industrial devices  128  that can include one or more of motors, pumps, chillers, air compressors, and the like. 
     In addition, control network  100  can comprise one or more control points  106  for receiving user inputs to control each of the one or more controllable devices. Control points  106  can be keypads, touch-panels, remote controls, and thermostats. For the purposes of this discussion, and in fulfillment of the dual purposes of clarity and brevity, control points shall herein after be referred to as keypads  106 . Additionally, keypads  106  can be user interfaces of the controllable devices themselves. Keypads  106  can transmit control commands to and through communication network  102  to control each of the other controllable devices of control network  100 , as well as communicate information to/from such controllable devices. For example, keypads  106  can communicate with each of the controllable devices or with controller  116  either directly or via one or more of gateways  114  and/or repeaters  130  (repeaters  130  can communicate with additions control networks  100   b , and/or communication networks  102   b , and so on). 
     According to further aspects of the embodiments, keypad  106  can comprise feedback indicators to provide feedback to the user. The feedback indicators can include any combination of visual feedback indicators, haptic feedback indicators, and audible feedback indicators. Feedback indication control can be provided by keypad  106  upon receiving a user input, upon requesting feedback, or upon a change in the status of any of the controllable devices  108 - 130 , and PED  104 . 
     Such controllable lighting devices  110  and controllers  116  can be manufactured by Crestron Electronics Inc., of Rockleigh, N.J.

     As described above, sensors  108  can be included in control network  100  according to aspects of the embodiments. Such sensors  108  can include occupancy sensors, and motion sensors, as well as sensors  108  related to fire and smoke detection, bio-hazard sensors, and the like. The one or more sensors  108  can comprise the following devices, each available from Crestron Electronics, Inc. of Rockleigh, N.J.: GLS-OIR-CSM-EX-BATT battery-powered infiNET EX® occupancy sensor. 
     Controller  116  can be connected to the various controllable devices via either or both of a wired and wireless connection. The one or more controllers  116  can be a DIN-AP3MEX DIN Rail 3-Series® Automation Processor with infiNET EX®, or an MC3 3-Series Control System® with infiNET EX®, each of which are available from Crestron Electronics Inc. of Rockleigh N.J. Any one or more of these controllers  116  can provide a substantially complete integrated automation solution. According to aspects of the embodiments, the various controllable devices of the facility or enterprise become integrated and accessible through operation of controller  116 . According to further aspects of the embodiments, controller  116  can be a server, a personal computer (PC), or any other electronic device capable of processing electrical signals. Still further, according to further aspects of the embodiments, controller  116  further comprises a web x-panel project, to allow for PC based setup. According to still further aspects of the embodiments, controller  116  can be a device manufactured by Crestron Electronics, Inc., of Rockleigh, N.J., comprising a PYNG-HUB. As shown in  FIG. 1 , controller  116  and gateway  114  can be arranged as two separate devices, but, as indicated by the dashed line forming a box around  114 ,  116 , they can be arranged to be one device, or contained within a single enclosure. 
     According to still further aspects of the embodiments, each of the devices in  FIG. 1  can be interconnected with other components in either or both of a wired or wireless manner. For example, PED  104  can connect to internet  132  via a cellular communications interface, or can be connected through router/firewall device  136  using conventional Ethernet cables. And, as shown in  FIG. 1 , PED  104  can be connected to LAN  134  via a wired interface (typically a category 5 type cable, i.e., Ethernet cable), or via a wireless interface such as the Wi-Fi connection that is also shown. According to still further aspects of the embodiments, each of the controllable and controlled devices of  FIG. 1 , such as sensors  108 , controller  116 , and gateway device  114 , can use a wireless protocol such as infiNET EX. Other wireless communications protocols can also be used. 
       FIG. 2  is a block diagram of controller  116  for use with control network  100  according to an aspect of the embodiments. Controller  116  can be used to control various controllable devices, such as, for example, those described and discussed above that include, among others, controllable devices  108 ,  110 ,  112 ,  118 ,  120 ,  122 ,  124 ,  126 ,  128 , and  130  (security devices (e.g., door locks), lighting system devices, blinds/drapes, HVAC system devices, and sensors such as motion sensors, among many others). One or more controllers  116  can comprise one or more logic engines for processing control commands. 
     Controller  116  can include at least one central processing unit (CPU)  202 , as well as internal bus  220 , the operation of which is known to those of skill in the art. For example, CPU  202  can represent one or more microprocessors, and the microprocessors may be “general purpose” microprocessors, a combination of general and special purpose microprocessors, or application specific integrated circuits (ASICs). Additionally, or alternatively, the CPU  191  may include one or more reduced instruction set processors (RISC), video processors, or related chip sets. CPU  22  can provide processing capability to execute an, run various applications, and/or provide processing for one or more of the techniques described herein. Applications that can run on controller  116  can include, for example, software for processing control commands, software for managing a calendar, software for controlling other electronic devices via a control network as noted above, among other types of software/applications. 
     Controller  116  can further include main memory  206 , which can be communicably coupled to CPU  202 , and which can store data and executable code, as known to those of skill in the art. Main memory  206  can represent volatile memory such as random access memory (RAM), but may also include nonvolatile memory, such as read-only memory (ROM) or Flash memory. In buffering or caching data related to operations of CPU  202 , main memory  206  can store data associated with applications running on controller  116 . 
     Controller  116  can also further include nonvolatile storage  204 . Nonvolatile storage  204  can represent any suitable, nonvolatile storage medium, such as a hard disk drive (HDD) or nonvolatile memory, such as flash memory. Being well-suited to long-term storage, nonvolatile storage  204  can store data files such as media, software, and preference information. Nonvolatile storage  204  can be removable and interchangeable, thereby allowing portability of stored files, such as project files, created during programming of control network  100 . According to aspects of the embodiments, project files can be used to map user desires into functions; as used thusly, project files are configuration files. These project files describe all the devices control system  100  knows about, what their buttons are configured to do, what types of devices they are, how they operate, and the operating parameters, among other features of each controllable device associated with control network  100 . According to further aspects of the embodiments, project files can also be used to keep track of scheduling data, which users are using the system (e.g., identifiable by PED  104 ). 
     Also shown as part of controller  116  is network interface  208 . Network interface  208  provides interface capability with one or more of several different types of network interfaces, including LR-PAN transceiver  212 , WLAN transceiver  214 , and cellular transceiver  216 . Each of transceivers  212 ,  214 , and  216  can provide wireless connectivity for controller  116  via respective ones of first, second, and third antennas  115 ,  117 , and  119 . Network interface  208  can represent, for example, one or more network interface controllers (NICs) or a network controller. As those of skill in the art can appreciate, the difference between a LAN and PAN can be less certain, and more one of degree; that is, in some cases, PANs are defined as those interconnections of devices that are within a few meters of each other, while other definitions indicated that devices that are within ten meters or so and are interconnected in a manner that can be considered to be within a PAN. Regardless of the exact definition, or, if no exact definition should ever exist, control system  100  can make use of each of a WAN, LAN, and PAN, or sometimes two or all three at one time, depending on the circumstances, as those of skill in the art can now appreciate. 
     According to certain aspects of the embodiments, network interface  208  can include LR-WPAN transceiver  212 . LR-WPAN transceiver  212  can provide capabilities to network with, for example, a Bluetooth® network, a near field communication (NFC) type network, an IEEE 802.15.4 (e.g. ZigBee) network among others. As can be appreciated by those of skill in the art, the networks accessed by LR-WPAN transceiver  212  can, but do not necessarily, represent low power, low bandwidth, or close range wireless connections. LR-WPAN transceiver  212  can permit one electronic device to connect to another local electronic device via an ad-hoc or peer-to-peer connection. However, the connection can be disrupted if the separation between the two electronic devices exceeds the proscribed range capability of PAN interface  212 . As those of skill in the art can appreciate, the networks described by IEEE 802.15.4 are mesh-type networks, and operate with a central router/coordinator; in control network  100 , the function of such central coordination is performed by one or more controller  116  and/or gateway  114 , according to aspects of the embodiments. 
     Network interface  208  can also include WLAN transceiver  214 . WLAN transceiver  214  can represent an interface to a wireless LAN, such as an 802.11 wireless network. The range of WLAN transceiver  214  can generally exceed the range available via LR-WPAN transceiver  212 . Additionally, in many cases, a connection between two electronic devices via WLAN transceiver  214  can involve communication through a network router or other intermediary device (not shown in  FIG. 2 ). WLAN transceivers  214  can also incorporate an ultra-wideband network. 
     According to further aspects of the embodiments in regard to controller  116 , network interfaces  208  can include the capability to connect directly to a WAN via cellular transceiver  216 . Cellular transceiver  216  can permit connection to a cellular data network, such as the enhanced data rates for global system for mobile communications (GSM) Evolution (EDGE) (also known as enhanced general packet radio service (GPRS) (EGPRS), or international mobile telecommunications (IMT) single carrier (IMT-SC) EDGE network, or other third generation/further generation (3G/4G) cellular telecommunication networks (a detailed discussion of which is both not needed to understand the aspects of the embodiments, and beyond the scope of this discussion). When connected via cellular transceiver  216 , controller  116  can remain connected to the internet and, in some embodiments, to one or more other electronic devices, despite changes in location that might otherwise disrupt connectivity via LR-WPAN transceiver  212 , or WLAN transceiver  214 . Also shown in  FIG. 2  as a component of controller  116  is internal bus  220 , which provides signal and data flow to and between all of the internal components of controller  116  in a manner known to those of skill in the art. 
     As known by those of skill in the art, Ethernet connectivity enables integration with IP-controllable devices and allows controller  116  to be part of a larger managed control network. Whether residing on a sensitive, security-conscious corporate LAN  134 , a home network, or accessing Internet  132  through a cable modem, controller  116  can provide secure, reliable interconnectivity with IP-enabled devices, such as touch screens (which can be part of keypad  106 ), computers, mobile devices, video displays, Blu-ray Disc® players, media servers, security systems, lighting, HVAC, and other equipment—both locally and globally. 
     Controller  116  can also include one or more wired input/output (I/O) interface  210  for a wired connection between controller  116  and one or more electronic devices. Wired I/O interface  210  can represent a serial port. A serial port, as those of skill in the art can appreciate, is a serial communication physical interface through which information transfers in or out one bit at a time (as opposed to a parallel port, which transmits several bits (typically in groups of 8 bits wide) substantially simultaneously). While it is known that interfaces such as Ethernet, FireWire, and USB, all send data as a serial stream, the term “serial port” usually identifies hardware more or less compliant to the RS-232 standard, intended to interface with a modem or with a similar communication device. 
     Wired I/O interface  210  can also represent, for example, a Cresnet port. Cresnet provides a network wiring solution for Crestron keypads, lighting controls, thermostats, and other devices that do not require the higher speed of Ethernet. The Cresnet bus offers wiring and configuration, carrying bidirectional communication and 24 VDC power to each device over a simple 4-conductor cable. 
     One or more infrared (IR) interfaces can also be part of wired I/O interface  210 ; the IR interface can enable controller  116  to receive and/or transmit signals with infrared light. The IR interface can comply with an infrared data acquisition (IrDA) specification for data transmission. Alternatively, the IR interface can function exclusively to receive control signals or to output control signals. The IR interface can provide a direct connection with one or more devices such as a centralized AV sources, video displays, and other devices. 
     Controller  116  can also include, but not necessarily, one or more programmable relay ports  218   a - c . Programmable relay ports  218  can be used by controller  116  to control window shades, projection screens, lifts, power controllers, and other contact-closure actuated equipment. Controller  116  can include, as programmable relay port  218 , a “Versiport” relay port that is manufactured by Crestron Electronics Inc., of Rockleigh, N.J. The Versiport relay port can be managed by a DIN- 108  module (also manufactured by Crestron Electronics Inc.), which is a DIN rail-mounted automation control module that provides eight Versiport I/O ports for interfacing with a wide range of third-party devices and systems. Each “Versiport” can be configured via software to function as a digital or analog sensing input, or as a digital trigger output. When configured as a digital input, the Versiport can sense a contact closure or logic level signal from devices such as motion detectors, partition sensors, alarm panels, 12V triggers, and all types of switches and relays. When configured as an analog input, the Versiport can sense changes in a resistance or DC voltage level, working with everything from temperature and light sensors to water level meters to volume control potentiometers. When operating as a digital output, the Versiport provides a logic level closure signal to trigger control and alarm inputs on a variety of external devices. 
     Thus, one or more “Versiport” programmable relay ports  218  can enable the integration of occupancy sensors, power sensors, door switches, or other devices by providing a dry contact closure, low-voltage logic, or 0-10 Volt DC signal. 
     By leveraging remote access of controller  116 , a user can control one or more of the controllable devices and/or environment settings in a facility (home, place of business or manufacture, or enterprise location) from substantially anywhere in the world using PED  104 . Such control can be accomplished by a dynamic domain name system (DNS) service. Those of skill in the art can appreciate that DNS is a hierarchical distributed naming system used for computers, services, or any resource that is connected to the internet or a private network. According to further aspects of the embodiments, controller  116  can be configured to utilize dynamic host communication protocol (DHCP) communications that include a hostname prefixed by a model number. A more detailed discussion of the internal operation of controller  116  is not needed to understand the various aspects of the embodiments described herein, and therefore is beyond the scope of discussion herein. However, such detailed discussion can be found in the aforementioned Applicants&#39; U.S. Non-Provisional Patent Application, as referenced above. 
     According to aspects of the embodiments, controller  116  hosts a project file, such as a Crestron Core 3 project file, also referred to as “Smart Graphics [Project],” which is intended to be used by one or more mobile devices (such as PED  104 ) with a control application (App) such as a Crestron App (located on PED  104 ). As described above, one or more project files can be created during the installation of control network  100 . The Crestron App is designed to receive and render the Smart Graphics project file. The Crestron App is responsible for communicating taps and feedback to the user. Additionally, Smart object App can be created for use with a local Crestron Mobile Pro Project as well as with foreign AV processors. The Crestron Mobile Pro project can contain just a Core 3 Smart Object and nothing else. The Smart Graphics Project file, located on controller  116 , is a collection of items that are meaningful in some way to a control system program, such as Crestron App. This collection of items can include things like “buttons,” “sliders,” or “text” (among other graphical representations). According to further aspects of the embodiments, Smart graphics project file can include “smart object” file, which can be a predefined conglomeration of other objects (buttons, slides, among others). For example, a lighting smart object file can comprise a slider to report/set a light level, and a few buttons to raise/lower and turn on/off the lights. According to further aspects of the embodiments, in control network  100 , smart object file talks directly to a Pyng-HUB, such as controller  116 . As such, smart object files can be used in or by any smart graphics project file, and they&#39;ll communicate with control network  100  and Crestron App, even if the project (i.e., the program currently being executed) is intended to control an external AV processor. 
     Referring back to  FIG. 1 , control network  100  further comprises communication network  102  that provides access with and between devices of control network  100  according to aspects of the embodiments. Communication network  102  can be a PAN, LAN, metropolitan area network, WAN, an alternate network configuration, or some other combination of network types and/or topologies. 
     According to an aspect of the embodiments, communication network  102  can employ both wired and wireless communication protocols. For example, the controllable devices can form communication network  102  with gateway device  114  (operating in a wireless manner) by communicating over a short range communication protocol such as Crestron infiNET EX wireless protocol (e.g., the IEEE 802.15.4 wireless protocol). Or, according to a different aspect of the embodiments, gateway device  114 , operating in a wired manner, can form a LAN with PED  104  communicating via Ethernet protocols using a wire-based Ethernet capability (it can also do so in a wireless manner). According to a further aspect of the embodiments, controller  116  or PED  104  can connect via a WAN such as the world wide web to access data stored on a remote server (not shown in  FIG. 1 ). 
     According to further aspects of the embodiments, communication network  102  can be a public switched telephone network (PSTN). Alternatively, communication network  102  can further include a cable telephony network, an internet protocol (IP) telephony network, a wireless network, a hybrid cable/PSTN network, a hybrid IP/PSTN network, a hybrid wireless/PSTN network, or any other suitable communication network  102  or combination of communication networks. In addition, other network embodiments can be deployed with many variations in the number and type of devices, communication networks, the communication protocols, system topologies, and myriad other details without departing from the spirit and scope of the aspects of the embodiments. 
     Referring now to  FIG. 3 , control network  100  can include one or more gateway devices  114 . According to a further aspect of the embodiments, controller  116  further comprises a built-in gateway  114 . According to still further aspects, control network  100  can comprise an external gateway  114 , such as a CEN-RFGW-EX gateway, available from Crestron Electronics, Inc. 
     According to aspects of the embodiments, gateway  114  of control network  100  provides network devices with an entrance to communication network  102  through controller  116  and can include software and/or hardware components to manage traffic entering and exiting communication network  102  and conversion between the communication protocols used by the network devices and communication network  102 . 
     Gateway  114  can be configured to operate in both a wired a wireless manner and act as the network coordinator, and can further manage network configurations. Additionally, gateway  114  can be configured to communicate with controller  116  via wired I/O interface  210 , such as an Ethernet interface (IEEE 802.3). One such gateway  114  according to an aspect of the embodiments is the CEN-RFGW-EX wireless gateway manufactured by Crestron Electronics, Inc., and which is a two-way radio frequency (RF) gateway\transceiver designed to enable communications and management for a complete infiNET EX wireless network of dimmers, keypads, remote control devices (RCDs), among other types of devices. The CEN-RFGW-EX wireless gateway links the infiNET EX network to a Crestron control system via a wired connection such as Ethernet or Cresnet. infiNET EX dimmers, switches, keypads, thermostats, and other devices, can be linked to controller  116  via a single CEN-RFGW-EX gateway  114 . Additional gateways  114  can be installed to support more devices. Wireless expanders (not shown in  FIG. 1 ) can be added wherever needed to extend control network  100  by filling in gaps between devices. That is, according to aspects of the embodiments, expanders can reinforce the network when operating in accordance with mesh networks principles. 
       FIG. 3  illustrates a block diagram of gateway  114  according to an aspect of the embodiments. Gateway  114  can include one or more transceivers  212 ,  214 , and  216 , which can provide connectivity for gateway  114  when acting in a wireless manner. In addition to the transceivers  212 ,  214 ,  216 , gateway  114  can further include a NWI that comprises one or more network interface cards (NICs), or network controllers (NWCs). In certain embodiments, the network interface can include LR-WPAN transceiver  212 , which can provide capabilities to network with, for example, a Bluetooth® network, NFC network, or a ZigBee/Infinet network, among others. As can be appreciated by those of skill in the art, the networks accessed by LR-WPAN transceiver  212  can, but do not necessarily, represent low power, low bandwidth, or close range wireless connections, such as that used by second antenna  117 . LR-WPAN transceiver  212  can permit one electronic device to connect to another local electronic device via an ad-hoc or peer-to-peer connection. 
     Gateway  114  can further include wired I/O interface  210 , which can represent an interface to a wired Ethernet-based network. Gateway  114  includes WLAN transceiver  214 , which can access an IEEE 802.11x wireless network. The range of the WLAN interface (WLAN transceiver  214 ) can generally exceed the range available via the PAN interface. Additionally, in many cases, a connection between two electronic devices via the LAN interface can involve communication through a network router or other intermediary devices. As discussed above, gateway  114  further comprises LR-WPAN transceiver  212  that can access an IEEE 802.15.4 (e.g. ZigBee/InfiNet) network. As those of skill in the art can appreciate, the networks described by IEEE 802.15.4 are mesh-type networks, and operate with a central router/coordinator; in control network  100 , the function of such central coordination is performed by one or more controller  116  and/or gateway  114 , according to aspects of the embodiments. 
     In a wired configuration, wired I/O interface  210  can be a LAN power-over-Ethernet (PoE) interface that can be fashioned using an 8-wire RJ-45 female connection with two LED indicators. According to a further aspect of the embodiments, a another type of NWI can be Cresnet interface  302   b , which is a 4-pin 3.5 millimeter (mm) detachable terminal block providing an interface for Cresnet proprietary communications on a LAN that includes power-over-Ethernet (PoE). The PoE interface can be configured for receiving both an electric power signal and an information signal from a control network. For example, Cresnet interface  302   b  can be connected through category 5 cable (CAT 5) to a LAN that contains a power supply, multiple control points, and signal generators. Through Crestnet interface/LAN PoE interface  302   b , gateway  114  can interface with control network  100 . For example, gateway  114  (which can be both wired and wireless) can communicate with controller  116 , such as a PRO3 available from Crestron Electronics, Inc. 
     Gateway  114  comprises one or more connectors, indicators and interface buttons, as well as an antenna connection for the supplied antenna. Gateway further comprises LED indicators, such as power on/off LED  304 , network activity indicator LED  306 , and activity indicator LED  308 . Power on/off LED  304  is an indicator that shows that operating power is being supplied to gateway  114  whether from the Cresnet network or a PoE connection. Network LED indicator  306  shows that communication with the Cresnet system is occurring. Activity indicator LED  308  shows that wireless communications are occurring, such as those that involve the elements of the wireless PAN. 
     Gateway  114  further comprises acquire button  310  and setup button  312 . Acquire button  310  and setup button  312  can be recessed push buttons each with an indicator LED. Acquire button  310  can be employed to configure communication with the PAN and setup button  312  can be employed to configure communication with control network  100 . 
     Gateway  114  can be placed in the “Acquire” mode via acquire button  310  or a different means, such as the pushing of certain buttons in a certain order. The associated LED can indicate that gateway  114  is in the “Acquire” mode. Once gateway  114  has been placed in the “Acquire” mode, the joining device can be brought into range and can be placed in the “Acquire” mode to be acquired by gateway  114  through a certain sequence. Such sequence involves the pushing of buttons in a certain, specific order, a detailed discussion of which has been omitted in fulfilment of the dual purposes of clarity and brevity. By pushing acquire button  310  a second time (within a predetermined time period), gateway  114  can exit the “Acquire” mode as indicated by the LED-illuminated acquire button  310 . 
     As discussed above, control network  100  can further comprise PED  104 . PED  104  can be a smart phone, tablet, remote control, personal digital assistant (PDA), or any other electronic device configured for presenting a user interface, such as a graphical user interface (GUI) and receiving user inputs, such as in the form of selections from a graphic user interface. 
       FIG. 4  illustrates a block diagram of a personal electronic device  104  for use with control system  100  according to aspects of the embodiment. PED  104  can include at least one central processing unit (CPU)  402 . For example, CPU  402  can represent one or more microprocessors, and the microprocessors can be “general purpose” microprocessors, a combination of general and special purpose microprocessors, or ASICs. Additionally, or alternatively, CPU  402  can include one or more reduced instruction set (RISC), advanced RISC machine (ARM), or complex instruction set (CISC) processors, video processors, or related chip sets. CPU  402  can provide processing capability to execute an operating system (OS), run various applications, and/or provide processing for one or more of the techniques described herein. Applications that can run on PED  104  can include, for example, software for managing and playing AV content, software for managing a calendar, software for controlling telephone capabilities, software for controlling other electronic devices via a control network as noted above, as well as software for controlling various other functions and interconnected devices. 
     PED  104  further comprises main memory  414 , which can be communicably coupled to CPU  402 , and which may store data and executable code. Main memory  414  can represent volatile memory such as RAM, but can also include nonvolatile memory, such as ROM or flash memory. In buffering or caching data related to operations of CPU  402 , main memory  414  can store data associated with applications running on PED  104 . 
     PED  104  can also include nonvolatile storage  412 . Nonvolatile storage  412  can represent any suitable nonvolatile storage medium, such as a HDD or nonvolatile memory, such as flash memory. Being well-suited to long-term storage, nonvolatile storage  412  may store data files such as media, software and preference information. Nonvolatile storage  412  can be removable and interchangeable, thereby allowing portability of stored files such as project files created during programming of control network  100 . Those of skill in the art can appreciate that data associated with controlling certain other electronic devices, such as a project file for a control application, can be saved in nonvolatile storage  412 . 
     Display  410  can display images and data for PED  104 . As those of skill in the art can appreciate, display  410  is optional. If included in PED  104 , however, display  410  can use any type of display technology, such as, but not limited to, a liquid crystal display (LCD), a light emitting diode (LED) based display, an organic light emitting diode (OLED) based display, a cathode ray tube (CRT) display, or an analog or digital television, among other types. According to other aspects of the embodiments, display  410  can function as a touch screen display through which a user can interact with PED  104 . 
     PED  104  can further include user interface  408 . User interface  408  can include indicator lights and user input structures, but can also include a GUI on display  410 . As those of skill in the art can appreciate, user interface  408  can operate via CPU  402 , using memory from main memory  414  and long-term storage in nonvolatile storage  412 , among using other types of memory (such as an HDD, not shown in  FIG. 4 ). According to aspects of the embodiments, if display  410  is not included in PED  104 , indicator lights, sound devices, buttons, and other various input/output (I/O) devices can allow a user to interface with PED  104 . If, however, display  410  is included in PED  104  and uses a GUI, user interface  408  can provide interaction with interface elements on display  410  via certain user input structures, user input peripherals such as a keyboard or mouse, or a touch sensitive implementation of display  410 . 
     As can be appreciated by those of skill in the art, one or more applications can be opened and accessible to a user via user interface  408  and displayed on display  410  of PED  104 . One or more of the opened applications can be run on CPU  402  in conjunction with main memory  414 , nonvolatile storage  412 , display  410 , and user interface  408 . Instructions stored in main memory  414 , nonvolatile storage  412 , or CPU  402  (CPU  402  can have its own internal storage, of many different types), of PED  104  can enable a user to install control network  100 . As such, those of skill in the art can appreciate that the instructions for carrying out such techniques on PED  104  can represent a standalone application, a function of the OS on PED  104 , or a function of the hardware of CPU  402 , main memory  414 , nonvolatile storage  412 , or other hardware of PED  104 . 
     One such application that can be opened and accessible to the user is a configuration application for installing control network  100  according to an aspect of the embodiments. The configuration application can be downloaded from an application marketplace such as from the Google Play application marketplace or the Apple iTunes® application marketplace, among other market places available through the internet, or other networks. 
     As briefly described above, the project file provides the instructions allowing the control application to communicate with the target control network (control network  100 , according to aspects of the embodiments). Further, the project file comprises the menu pages of the control application corresponding to the locations of controllable devices. For example, the control application can display one or more menu pages identified by page identities for controlling the one or more controllable devices on control network  100  according to the project file. The menu pages comprise selectable elements corresponding to control functions as defined in the project file. 
     The configuration application displays a series of menu pages comprising selectable elements and graphical elements. As will be described in greater detail below, the one or more of the selectable elements can correspond to initialization functions of the configuration application. PED  104  can transmit signals to control network  100  according to the initialization functions selected by the user. Additionally, control network  100  can communicate with PED  104 , such as by providing feedback signals to PED  104 . According to an aspect of the embodiments, PED  104  can communicate with controller  116  running a logic engine via communication network  102 . Gateway  114 , according to further aspects of the embodiments, can be used to relay commands and return status information to and from sensors  108  and from the various controllable devices  110 ,  112 ,  118 ,  120 ,  122 ,  124 ,  126 ,  128 , and  130   
     According to various aspects of the embodiments, PED  104  can include location sensing circuitry  406 . Location sensing circuitry  406  can comprise global positioning system (GPS) circuitry, but can also represent one or more algorithms and databases, stored in nonvolatile storage  412  or main memory  414  and executed by CPU  402 , which may be used to infer the location of PED  104  based on various observed factors. For example, location sensing circuitry  406  can represent an algorithm and database used to approximate geographic location based on the detection of local 802.11x (Wi-Fi) networks or nearby cellular phone towers. 
     PED  104  can also include wired input/output (I/O) interface  210  for a wired interconnection between a first electronic device and a second electronic device. Wired I/O interface  210  can represent, for example, a universal serial bus (USB) port, an IEEE 1394 port, or a FireWire® port. However, wired I/O interface  210  can also represent a proprietary connection. Additionally, wired I/O interface  210  interface can permit a connection to user input peripheral devices, such as a keyboard or a mouse. In addition to wired input/output (I/O) interface  210 , PED  104  further comprises infrared (IR) interface  430  that can enable PED  104  to receive and/or transmit signals with infrared light. By way of example, IR interface  430  can comply with an infrared IRDA specification for data transmission. 
     One or more network interfaces  208  can also be provided in PED  104 . One or more of such network interfaces  208  can provide additional connectivity for PED  104 . Network interfaces  208  can represent, for example, one or more network interface cards (NIC) or a network controller. In certain embodiments, the network interface  208  can include LR-WPAN transceiver  212 . LR-WPAN transceiver  212  can provide capabilities to network with, for example, a Bluetooth® network, an NFC network, or a ZigBee/CresNet network. As should be appreciated, the networks accessed by LR-WPAN transceiver  212  can, but do not necessarily, represent low-power, low-bandwidth, or close range wireless connections. However, as those of skill in the art can appreciate, the connection in a PAN can be disrupted if the separation between the two electronic devices exceeds the operational range capability of LR-WPAN transceiver  212 . LR-WPAN transceiver  212  can permit one electronic device to connect to another local electronic device via an ad-hoc, or peer-to-peer connection, such as that defined by the wireless PAN protocol IEEE 802.15.n, communications network  102 . 
     LR-WPAN transceiver  212  can also incorporate IEEE 802.15.4 (e.g. ZigBee) network, or an ultra-wideband network. As those of skill in the art can appreciate, the networks described by IEEE 802.15.4 are mesh-type networks, and operate with a central router/coordinator; in control network  100 , the function of such central coordination is performed by either or both of controller  116  and/or gateway  114 , according to aspects of the embodiments. 
     Network interface  208  can also include WLAN transceiver  214 . WLAN transceiver  214  can represent an interface to a wireless LAN, such as an IEEE 802.11x wireless network (Wi-Fi). The wireless operating range capability of LAN interface  426  can generally exceed the wireless operating range capability available via LR-WPAN transceiver  212 . Additionally, in many cases, a connection between two electronic devices via WLAN transceiver  214  can involve communication through a network router or other intermediary devices. In PED  104  WLAN transceiver  214  interfaces with first antenna  115 , WLAN transceiver  212  interfaces with second antenna  117 , and cellular transceiver  216  interfaces with third antenna  119  according to aspects of the embodiments. Communications network  134  is a wired or wireless LAN, such as that defined by IEEE 802.11.n (Wi-Fi), or 802.3 (Ethernet). 
     According to further aspects of the embodiments, network interfaces  208  of PED  104  can further include the capability to connect directly to a WWAN via cellular transceiver  216 , and third antenna  119  according to aspects of the embodiments. Cellular transceiver  216  can permit a connection to a cellular data network, such as an EDGE network, or another 3G/4G network, among others. When connected via cellular transceiver  216 , PED  104  can remain connected to the internet and, in some embodiments, to other electronic devices, despite changes in location that might otherwise disrupt connectivity via LR-WPAN transceiver  212 , or WLAN transceiver  214 . As will be discussed in greater detail below, wired I/O interface  210  and network interfaces  208  can represent both low- and high-bandwidth communication channels for transferring user data using the simplified data transfer techniques discussed herein. 
     PED  104  can also include near field communication (NFC) interface  416 . NFC interface  416  can allow for extremely close range communications at relatively low data rates (e.g., about 464 kilo-bits/second (kb/s)), and can comply with such standards as International Standards Organization (ISO)  18092  or ISO 21521, or it can allow for close range communications at relatively high data rates (e.g., about 560 mega-bits/second (Mb/s)), and can comply with the TransferJet® protocol. NFC interface  416  can have a range of between about 2 to about 4 centimeters (cm) (or between about 0.78″ to about 1.57″). The close range communication with NFC interface  416  can take place via magnetic field induction, allowing NFC interface  416  to communicate with other NFC interfaces, or to retrieve information from tags having radio frequency identification (RFID) circuitry. As discussed in greater detail below, NFC interface  416  can provide a manner of initiating or facilitating a transfer of user data from one electronic device to another electronic device. 
     PED  104  can also include camera  420 . With camera  420 , PED  104  can obtain digital images or videos. In combination with optical character recognition (OCR) software, barcode-reading software, or matrix-code-reading software running on PED  104 , camera  420  can be used to input data from printed materials having text or barcode information. Such data can include information indicating how to control another device from a matrix barcode that can be printed on the other device, as described in greater detail below. 
     According to further aspects of the embodiments, PED  104  can also include one or more accelerometers  418  that can sense the movement or orientation of PED  104 . Accelerometers  418  can provide input or feedback regarding the position of PED  104  to certain applications running on CPU  402 . According to further aspects of the embodiments, accelerometer  418  can be provided by devices made using microelectromechanical system (MEMS) technology. MEMS devices, which can be defined as die-level components of first-level packaging, can include pressure sensors, accelerometers, gyroscopes, microphones, digital mirror displays, microfluidic devices, among other devices. 
     According to aspects of the embodiments, control network  100  can be configured to be installed by untrained users executing a configuration application on PED  104 . According to further aspects of the embodiments, the control system and associated configuration application are referred to as Pyng, which are software programs created and manufactured by Crestron Electronics, Inc., of Rockleigh, N.J. 
     One such application that can be opened and accessible to the user is a configuration application for installing control network  100  according to an aspect of the embodiments. The configuration application can be downloaded from an application marketplace such as from the Google Play application marketplace, or the Apple iTunes® application marketplace, among other application market places available through the internet, or other networks. A detailed discussion of the configuration application is both not needed to appreciate the various aspects of the embodiments, and can be found in the U.S. Non-provisional Patent Application referenced above; as such, a detailed discussion has been omitted in fulfillment of the dual purposes of clarity and brevity. 
     Attention is now directed towards  FIG. 5 , which illustrates wall mount keypad (keypad)  106  that can be used in control network  100  as part of an acoustic sensory network (ASN) according to aspects of the embodiments. Keypad  106  includes display/touch panel  502  (an interactive display that can be a liquid crystal display (LCD) or light emitting diode display (LED), or combination thereof), microphone(s)  504 , optional audio processing board  505  (which comprises pre-amplifier  506 , analog-to-digital converter (ADC) 508, and 60 Hertz (Hz) notch filter according to an aspect of the embodiments), processor  512 , IEEE 811.15.4 LR-WPAN transceiver (transceiver)  212 , WLAN transceiver  214 , cellular transceiver  216  (and their respective antennas,  115 ,  117 , and  119 ), internal bus  516 , antenna  117 , LAN/Ethernet connector  518 , and voice recognition (VR) system-on-a-chip (SoC) circuit (VR SoC circuit)  520 . As those of skill in the art can appreciate, other components have been omitted from  FIG. 5  in fulfillment of the dual purposes of clarity and brevity, as they would not aid in understanding the various aspects of the embodiments. According to further aspects of the embodiments, the devices, software, algorithms, and other components of the ASN are described in reference to keypad  106  and controller  116 , but can be distributed in one or more of any of the devices of network  100 , e.g., gateway  114 . In addition, one or more of the components of the ASN can be separated from keypad  106 , such as microphones  504 , audio processing board  505 , and VR SoC circuit  520 , according to aspects of the embodiments. For example, either or both of audio processing board  505  (and its components) or VR SoC circuit  520  can be included in controller  116  or gateway  114 . However, in fulfillment of the dual purposes of clarity and brevity, and according to aspects of the embodiments, the following description of the devices, software, algorithms, and other components of the ASN shall be made in reference to keypad  106  and controller  116 . 
     The ASN according to aspects of the embodiments includes audio processing components to interpret spoken words as commands to control the controllable devices, including those of lights and related devices, in such a manner as to overcome the problems of the prior art as previously described. That is, the ASN can include one or more microphones  504   a,b , VR SoC circuit  520 , or, in the alternative, optional audio processing board  505 , to capture, process, and implement audible commands. As those of skill in the art can appreciate, VR SoC circuit  520  contains the necessary components to convert the audio signals received by each mic  504   a,b , into digital form, provide filtering before and/or after conversion to digital form, perform additional processing (as described in greater detail below), and can, according to aspects of the embodiments, include software to identify the word (or words) that were spoken to produce the digital words. Such processing can be referred to as acoustic finger printing, or voice recognition. Further, VR SoC circuit  520  can also provide a time stamp to the received audio signal, which can be further used in processing in a manner to be described below, or the time stamp can be provided by other circuitry, such as, for example, controller  116 . Optionally, substantially similar processing can occur in audio processing board  505 ; however, in fulfillment of the dual purposes of clarity and brevity, discussion shall only be made in regard to VR SoC circuit  520 . 
     According to still further aspects of the embodiments, either or both of VR SoC  520  and audio processing board  505  can be implemented in one or more of the dimmers, wall mounted touch panels, remote control devices, and the like, all of which can be considered to be part of control network  100  and the ASN according to aspects of the embodiments. 
     In cases where it is implemented, audio processing board  505  accepts as an input the analog audible signal (audible signal) received from each of microphones  504   a,b , applies a pre-amplification to the signal to scale it, then converts the same to a digital audible signal using ADC  508 . The “raw” output of ADC  508  can then be filtered by notch filter  510  to remove as much 60 Hz “hum” as possible, and the filtered digital audible signal (digital audible signal) can then be sent to processor  512  for further processing. 
     Attention is also directed to  FIG. 10 , which illustrates several audio processing blocks that can occur within either or both of audio processing board  505  and VR SoC circuit  520  according to aspects of the embodiments. In fulfillment of the dual purposes of clarity and brevity, however, reference will be made as to the processing blocks as occurring within VR SoC circuit  520 , although that need not necessarily be the case; one or more of the processing blocks shown is within VR SoC circuit  520  can also be implemented in one or more separate devices, such as ASICs, or even the processors of keypad  106 , controller  116 , and keypad  104 , among other devices of network  100 . 
     Referring now to  FIGS. 5 and 10 , microphones  504   a,b  receive audio commands spoken by a user or occupant of the home or enterprise location, along with other extraneous audio signals, the latter of which can be collectively referred to as audio noise; thus, the combined analog audio signal consists of an audio command and audio noise, and is represented as the analog audio signal from microphone  504   a , or AASa, and similarly from mic  504   b , AASb. Within VR SoC circuit  520 , both of the analog microphone output signals encounter analog processing circuit  1002   a,b  respectively. Analog processing circuit can include, among other circuitry, 60 Hz notch filters, one or more of a low pass filter, high pass filter and a bandpass filter, pre- and post-amplifiers, and an analog-to-digital converter (ADC). The output of analog processing circuits  1002   a,b  can be referred to as digital audio signal “a” and “b,” respectively, DASa, DASb. Although some noise has been removed, DASa,b both still contain ambient, background noise that can include one or more noise signals generated by fans, motors, audio sources, and non-command words, among others. 
     According to further aspects of the embodiments, upon conversion from an analog to digital form, each of DASa,b can have a time-date stamp applied to it. According to aspects of the embodiments, the application of a time-date stamp can be applied to the received digital audio signal by time-date stamp generator  1004 . As those of skill in the art can appreciate, any processing steps that occur at processor  512  of keypad  106  (or any other similarly situated control or controllable device of control network  100 ) can also occur in one or both of gateway  114  and controller  116 . The time-date stamp applied by time-date stamp generator  1004  can be used one or more different ways. For example, because each microphone&#39;s output can be time-stamped, it can be determined which microphone was closest to the source of the audio command (once processing occurs to decipher the command, discussed below). Further, because in subsequent processing the two microphones&#39; outputs are combined, a single average time stamp value can be generated and applied to the combined audio command output from the respective keypad  106 ; this average time stamp can then be used and compared to other time stamps generated by other keypads  106  to further ascertain which keypad first received the audio command. 
     There are several mechanisms through which time stamps can be generated and applied according to aspects of the embodiments. As those of skill in the art can appreciate, a certain degree of accuracy is required in generating the time stamp in order to make the time stamp useful in determining the order of arrival of audio signals. The speed of sound, Vs, is about 1126 feet-per-second (fps) at sea level, under certain predefined conditions. The speed varies with temperature, humidity, and altitude, as those of skill in the art can appreciate, but the generally accepted “norm” value of Vs of 1126 fps can be used for the purposes of this discussion. Using this value yields a travel time of about 888.1 microseconds-per-foot (μs/ft). Most clock speeds of the processors and other digital circuitry will operate at much higher frequencies than 1100 Hz; however, it is not the absolute clock frequency that is important (though below a certain value, as those of skill in the art can appreciate, time stamping would not be effective), but that the clock speeds be substantially identical at each keypad  106 , and be substantially in synchronization with each other, at least by several orders of magnitude in regard to the expected differences in time between when a first keypad marks the audio sound and a second keypad marks the same audio sound. According to aspects of the embodiments, there are several network communication protocols that can be used to generate time stamps of sufficient accuracy; one such system uses ZigBee, as described in papers entitled “Time Synchronization for ZigBee Networks,” Cox, D. et al., IEEE 0-7803-8808, September 2005, and “Non-invasive Time Synchronization for ZigBee Wireless Sensor Networks,” Ferrari, P., et al., IEEE 978-1-4244-2275, March, 2008, the entire contents of both of which are incorporated herein by reference. Time-date stamp generator  1004  uses either or both the protocols described above, among others not mentioned, and generates the time-date stamp that is then added to digital word represented the amplitude output from each respective microphone; in this manner, the digital word now resembles a packet of data familiar to those of skill in the art of digital data transmission using protocols such as the Open Source Initiative (OSI) model and internet protocols, among others. 
     According to still further aspects of the embodiments, application of the time-date stamp can occur in one or both of controller  116  or gateway  114  after the audible command has been received from each of the keypads, assigned an identifier header (or footer), and transmitted following digitization. Thus, the digitized audible commands can be sent in real time to controller  116  or gateway  114 . Considering the substantially instantaneous rate of communication from each keypad to the controller  116  (for purposes of this discussion, the use of controller  116  alone will be considered by means of a non-limiting example), such delay in time-date stamping can be negligible. According to further aspects of the embodiments, test communications can be sent to each keypad in order to ascertain a trip delay, and such delay time can be subtracted from each received audible command digital word after it has been received and time-date stamped, and prior to processing, as described below in regard to  FIG. 8 , and method  800 . 
     Following the application of the time-date stamp by time-date stamp generator  1004 , acoustic echo cancellation (AEC) algorithms can be applied through use of AEC processors  1006   a,b  to the respective digitals signals, DASa,b. The implementation and use of AEC processing is known to those of skill in the art, and therefore, in fulfillment of the dual purposes of clarity and brevity, a detailed discussion thereof need not be repeated herein. However, one known goal of use of AEC is to reduce extraneous media sounds from the digital audio signals. As those of skill in the art can appreciate, AEC can use an audio signal as a reference, and then cancels this reference signal from the microphone input. The reference signal can be provided to each AEC circuit from one or both of controller  116  and gateway  114 . Such reference signal can be the audio portion of any video that might be playing in each respective room of the corresponding keypad  106 , or audio signal that it being provided to amplifiers and speakers in each corresponding room. The AEC circuit uses a Least Mean Square (LMS) algorithm to create an adaptive filter used to eliminate the reference and acoustic echoes associate with it. In addition, non-linear adaptive filtering can also be used to further suppress this signal. According to aspects of the embodiments, this processing can occur in keypad  106 , and the reference signal will then be provided to each keypad  106  from the media system to the respective keypad  106  either through the IEEE 802.15.4 radio connection (LR-WPAN transceiver  212  and second antenna  117 ), IEEE 802.11 radio connection (WLAN transceiver  214  and first antenna  115 ), cellular transceiver  216  (and third antenna  119 ), or via the IEEE 802.3 LAN connection (wired I/O interface  210 ). According to further aspects of the embodiments, AEC blocks  1006   a,b  can also include reverb reduction and/or active noise cancellation, the operation of which are known to those of skill in the art. 
     Following AEC in AEC blocks  1006   a,b , the digital audio signal can be further processed and/or enhanced according to several further aspects of the embodiments. Each DAS from the respective microphones  504   a,b  in a first keypad  104   a  can have direction of arrival (DOA) processing performed in conjunction with directionally adapted beamforming (DABF); this processing can occur in DOA block  1008 , which, as shown in  FIG. 10 , comprises at least two inputs, the respective DASs from each microphone  504   a,b  in first keypad  104   a . The output of DOA block  1008  is another digital packet of data that includes the DOA processed digital audio signals and a relative angle that each microphone  504   a,b  received its analog audio signal. The DABF block  1010  receives that output from DOA block  1008  and uses the directional information (the relative angle) and further reduces the noise in the portion of the digital packet that represents the digitized and further processed audio signals. In this manner, the output of VR SoC circuit  520  has now substantially minimized or reduced the noise that accompanied the spoken command, so that the signal-to-noise ratio (SNR) has been improved of the spoken audio command. 
     A detailed discussion of the processing that occurs in either or both of DOA block  1008  and DABF block  1010  is not necessary to the understanding of the aspects of the embodiments; however, such processing is described in the following documents, the entire contents of each of which are incorporated herein in their entirety. Such documents include “A New DOA Estimation Method Using a Circular Microphone Array,” Karbasi, A., et al., School of Comp. and Commun. Sciences, Ecole Polytechnique Fed&#39;erale de Lausanne CH-1015 Lausanne, Switzerland, and Common Platform Software Research Labs., NEC Corporation Kawasaki 211-8666, Japan, 2007; “Direction of Arrival Estimation Using the Parameterized Spatial Correlation Matrix,” Dmochowski, J., et al., IEEE Transactions On Audio, Speech, and Language Processing, Vol. 15, No. 4, May 2007; and “Microphone Arrays: A Tutorial,” McCowan, I., derived from “Robust Speech Recognition using Microphone Arrays,” McCowan, I., PhD Thesis, Queensland University of Technology, Australia, 2001. 
     In addition, the following websites provide further information as to implementation of direction of arrival and directionally adaptive beamforming circuitry and processing: https://www.xmos.com/support/boards?product=35564, and http://www.vocal.com/voice/, both of which were current and available as of the date of filing of this U.S. Non-provisional Patent Application, and the entire contents of each of which are incorporated herein in their entirety. 
     According to aspects of the embodiments, DOA and DABF processing can be implemented at each keypad  106  in regard to the one or more microphones  504  in the respective keypad  106 , or, DOA and DABF processing can occur at a central location, such as in controller  116  and CPU  202  (or in gateway  114 , among other “central locations”). Or, according to still further aspects of the embodiments, DOA processing can occur at each keypad, and DABF processing can occur at the central location such as controller  116  and CPU  202 . Further, while it has been discussed and described that keypad  106  can have two microphones  504 , according to further aspects of the embodiments, keypads  106  can have one, three, or even more microphones  605 . Further still, one or more such microphones  504  can be stand alone units, i.e., one or more or a plurality of just microphones can be installed in one or more of the rooms/hallways of the home or enterprise location without keypad  106  in order to provide a larger area to listen for commands, and obtain more detailed spatial information about the location of the source of the audible command, as well as increasing the likelihood of accurately determining the room to which the command is being directed towards. 
     Following the processes described above, the digital audible signal can be processed by a speech recognition algorithm in order to attempt to discern the command that is contained in the digital audible signal. Such processing can be performed in each keypad  106 . According to further aspects of the embodiments, however, such processing shall be discussed from the perspective of occurring in controller  116 , within CPU  202 , in fulfillment of the dual purposes of clarity and brevity. However, those of skill in the art can appreciate that such any of this processing, as well as additional processing described and discussed above and below, can be distributed throughout a network such as network  100 , and could occur, for example, in one or more of gateway  114 . 
     For example, one such command could be “lights off,” as the person is leaving a bathroom. In a first scenario, it will be presumed that no extraneous noise exists, and that the command can only be heard by the keypad/processor in the room to which it is directed. Then, using a speech recognition algorithm in the respective keypad  106 , processor  512  could relatively easily act on the command, and turn off the lights in the bathroom. Such “turning off” command can be acted upon even if the same command was received by an adjoining bedroom because of the relatively high percentage of certainty of the true nature of the command contained in the digital audible signal. As those of skill in the art can appreciate, speech recognition capabilities can be located throughout a residential or commercial facility to facilitate control of devices in the residence/office/enterprise location. However, as has been discussed above, extraneous noise does exist and it cannot be said with any degree of certainty that processor  512  of keypad  106  in the bathroom would act on such command, or that the lights of the bedroom next door would not also be turned off, much to the surprise of the occupant therein. 
     Therefore, according to further aspects of the embodiments, further processing of the received audio command can also determine the amplitude of the received digital audible signal at each respective keypad  106 ; such amplitude can be used by CPU  202  in controller  116  (or another processor, such as processor  512 , though discussion will be directed to such processing occurring within CPU  202  from hereon in), to compare the amplitude of a plurality of received digital audible signals DAS N . Relative amplitude between all of the received signals can be used to assist in determining which of the received signals was received first, as amplitude falls off with distance, as time increases as well. Therefore, if one of the received audio signals has a larger amplitude than the other, then the microphone associated with the (digital) audible signal with the larger amplitude can be considered to be the device to which the command is directed towards, or at least it can be considered as a factor to take into account.  FIGS. 6 and 7 , which are described in greater detail below, illustrate the principles of operation of the time-date stamp and amplitude determination. 
     According to further aspects of the embodiments, either or both of additional processing and additional circuitry can be used that reduces the likelihood of misinterpreting the received digital audio signal. The first item to be considered is the use of two microphones  504   a,b  in each keypad  106 , as shown in  FIG. 5 . The outputs of mics  504   a,b  are both directed to VR SoC circuit  520 , or audio processing board  505 ; as discussed above, only use of the former will be described herein in fulfillment of the dual purposes of clarity and brevity. When two (or more) mics  504   a,b  are used, the effects of noise on the intended audio signal can be reduced. Some sources of noise can include other people speaking, fans in bedrooms or bathrooms, ceiling speakers, televisions, cell-phones, and the like. 
     Those of skill in the art can appreciate that a detailed discussion of the technology and processing required to implement noise reduction with the use of two or more mics  504  is not needed to understand the aspects of the embodiments. Nonetheless, the following is provided for completeness. Regardless of how far away the source of the audio signal, i.e., the voice command, one signal from a respective mic  504  will be stronger than the other. The two sound waves can be compared following filtering, digitization, and other processing. The non-voice signal, or the one with the lower amplitude can be subtracted from the other, meaning the voice or audible command signal is now cleaner, with less noise. 
     According to aspects of the embodiment, the ASN can be part of a larger control system, such as control network  100 . While the ASN can be part of control network  100 , or the ASN can operate autonomously, reference from hereon in shall be made to only the ASN. As shown in  FIG. 5 , microphone  502  can incorporated into existing devices such as keypads  500  and motion detectors, or can be stand-alone independent devices with communications capabilities such as IEEE 811.14 PAN transceiver  514 . Accordingly, each device can have local voice recognition capabilities (i.e., through the use of a “mini” processor that is co-located with the standalone microphone), of can be part of a centralized voice recognition system wherein voice recognition processing occurs at a remote server (such as gateway  114  or controller  116 ) or a combination of the two. 
     Attention is now directed towards  FIG. 6 , which illustrates the scientific principles upon which time-date stamping and amplitude determination are based. In  FIG. 6 , the source is shown as generating a sound; in this case, a “light-off” command directed towards room  1 . The sound waves, as indicated, travel in the direction of arrow A, towards first and second microphones  504   a   1  and  504   b   1  of keypad  106   a  in room  1 , and third and fourth microphones  504   a   2  and  504   b   2  of keypad  106   b  in room  2 . The sound waves arrive at first and second microphones  504   a   1 ,b 1  of keypad  106   a  in room  1  at times T 1′  and T 1″ , respectively, with amplitudes of A 1′  and A 1″ , respectively, wherein first microphone  504   a   1  is a distance d 1′  from the sound source, and second microphone  504   b   1  is a distance dr from the sound source. Similarly, the sound waves arrive at third and fourth microphones  504   a   2 ,b 2  of keypad  106   b  in room  2  at times T 2′  and T 2″ , respectively, with amplitudes of A 2′  and A 2″ , respectively, wherein third microphone  504   a   2  is a distance d 2′  from the sound source, and fourth microphone  504   b   2  is a distance d 2″  from the sound source. The calculations for determining the time in view of the velocity of sound are known to those of skill in the art, and therefore have been omitted herein in fulfillment of the dual purposes of clarity and brevity. 
     Accordingly, as the amplitude of the sound waves generally decreases with time and distance, the sound waves arriving at second microphone  504   b   1  should be somewhat smaller in amplitude, and arrive at a later time than those that arrive at first microphone  504   a   1 . And, the sound waves at third microphone  504   a   2  should be smaller and arrive at a later time than those of second microphone  504   b   1 , and so on for the fourth, and other microphones, depending on their spatial location with respect to the source of the sound. However, as those of skill in the art can appreciate, sometimes sound waves reflect off objects, causing larger amplitudes at farther distances, or become attenuated for a variety of reasons that might be different from one location to the other, even if the locations within a setting are within relatively short distances (meters, or yards), depending on the construction of the home or enterprise location. Thus, according to further aspects of the embodiments, amplitude or even time stamping might not be sufficiently dispositive in some cases in regard to the determination of which room the audible command is being directed towards, but in those circumstances they can be useful factors to take into account. 
       FIG. 7  illustrates a plan view of a floor of a house in which the system and method for determining which controllable device an audible command is directed to can be used according to aspects of the embodiments. Such a setting as discussed above can be as realized in  FIG. 7 , wherein room  1  is “Jordyn&#39;s Room” and room  2  is “Nolan&#39;s Room.” Someone has just left room  1 , at position ( 1 ), carrying bags in each hand, and cannot hit the light switch to turn off the lights on the way out. So, the person uses an audible command “Lights off,” as they pass position ( 2 ). However, both of microphone  504   a   1 ,b 1  (Jordyn&#39;s room, room  1 ) in keypad  106   a , and both of microphones  504   a   2 ,b 2  (Nolan&#39;s room, room  2 ) in keypad  106   b , receive the audible command, and there can be confusion as to which lights to turn off. There could be someone still in Nolan&#39;s room, and to turn off those lights could be dangerous, or at least inconvenient. Since the first pair of microphones  504   a   1 ,b 1  received the command earlier (through comparison of the time-date stamp), the controllable device associated with the first pair of microphones  504   a   1 ,b 1  of keypad  106   a  will be directed to respond to the audible command. This processing decision can also be made, or verified, by comparing amplitudes of the first and second digital signals—amplitude A 1  will be greater, albeit by a small amount, than amplitude A 2 , and as such whichever processor processes the received digital signals, it will ascertain that the command was directed to Jordyn&#39;s room, room  1 , because the amplitude of the received signal is greater at Jordyn&#39;s room than at Nolan&#39;s room. According to aspects of the embodiments, the user would prefer that the lights in Jordyn&#39;s room be turned off well before they get to position ( 3 )—the bottom of the stairs. 
     According to further aspects of the embodiments, the ASN can further include proximity sensors as a further means for discerning the presence or location of a user, which can assist in determining which room the command to the controllable device is directed towards. For example, in  FIG. 7 , there are shown a plurality of proximity sensors  702   a - d , one each for Jordyn&#39;s room, Nolan&#39;s room, Raegyn&#39;s room, and the bathroom, as well, as  702   e  for the hallway. According to further aspects of the embodiments, proximity sensors can be the same or different as occupancy sensors; that is, an occupancy sensor can be a passive detection device; motion, heat, among other types. Proximity sensors can be active—using near field communications (NFC), Bluetooth, Wi-Fi, or other low- or medium-power communications protocols, that transmit signals to which a device, such as PED  104 , can respond to, thereby tracking movement and position of the user, without the user&#39;s input. For example, in  FIG. 7 , the user, when at position ( 2 ), has left Jordyn&#39;s room and is now at the top of the stairs. While each of proximity sensors  702   a - e  can, most likely, detect the presence of the user, each will have a different power level received signal from PED  104  that the user is carrying with them. Of course, as those of skill in the art can appreciate, this means that the user has to have loaded onto their PED  104  a configuration application that contains a portion of the program dedicated to the particular low- or medium-power communications protocol being used by the ASN. Thus, a central processor, such as central processor  116  or gateway  114  will receive data from each of proximity sensors  702  and will be able to check the signal strength level from each of proximity sensors  702   a - e . The processor will therefore know that (a) the user has just left Jordyn&#39;s room, (b) is now headed down the stairs, and (c) that a command has just been issued by the user to turn off lights. A review of the light status of each of the rooms on that floor will determine that the lights were left on in Jordyn&#39;s room, and a command can now be generated and transmitted to turn them off. 
     While any one of the above proscribed processes can effectively turn off the light in the room as intended by the audible command—speech recognition algorithms, amplitude comparisons, time-date stamp comparisons, those of skill in the art can appreciate that additional problems can, from time to time, arise in the system and can potentially be the cause in erroneous operation. In some cases, any two of the three processes can be combined, or all three can be used. In addition, as immediately described below, additional processes can be implemented to construct an ASN that can operate substantially effectively, substantially all of the time. 
     As described above, according to aspects of the embodiments, one or more processors can obtain received digital audible signals (e.g., DAS 1  and DAS 2 ), and can process each of DAS 1  and DAS 2  using speech recognition algorithms to determine the nature of the command, if any, contained in DAS 1  and DAS 2 . If the command can be ascertained with a degree of certainty that meets or exceeds a predetermined degree of certainty (those of skill in the art can appreciate that currently available speech recognition algorithms can assign a value of certainty in regard to recognition of the speech of the received digital audio signals), then the controllable device to which the received digital audible signal is directed can be instructed to act on the command. Sometimes, however, such received digital audible signals are not recognizable by the speech recognition algorithms. In these cases, additional processing can be necessary to ascertain the device to which the received DAS is directed. In this latter case, a time-date stamp can be applied to each received DAS, and then those time-date stamps can be compared to make a determination as to which DAS occurred first. The controllable device associated with the microphone that received the first DAS can then be directed to act on the command. In addition to comparing time-date stamps, the amplitude of the received DAS can also be compared; the controllable device associated with the microphone that received the DAS with the larger amplitude can be considered to be the one to which the command was directed. Amplitude comparisons, time-date stamp comparison, and speech recognition can be used independently of each other, or in various combinations with each other. Other processes can also be used, as described below. 
     According to further aspects of the embodiments, to reduce false positives, the ASN can include speech recognition algorithm (SRA) that recognizes and distinguish audible commands from silence. The SRA can learn, over time, the ambient noise levels of the room in which a respective microphone is located. According to an embodiment, these ambient levels become characterized as “silence” in the sense that they do not convey useful command and control information, or can be actually very low noise/sound level situations. According to further aspects of the embodiments, the SRA can then determine a state of silence (or absence of a command), a state that a command has been issued, and then silence again. 
     To reduce collocation errors, the SRA of the ASN recognizes zone commands. For example, the SRA of the ASN can recognize commands such as “Master Bathroom Off” and “Guest Room On,” among others. In order to reduce errors in the acoustic sensory network, a user can speak such commands in a learning mode to that the SRA can learn to recognize the different vocal traits of the user or users. According to further aspects of the embodiments, any number of users can input “practice” commands that can then be learned by the SRA. However, as those of skill in the art can appreciate, the SRA and acoustic sensory network is not necessarily limited to such “learned” commands, nor does it even require such learned commands in order to recognize zone commands. However, by knowing the different zones beforehand, the SRA and acoustic sensor network can increase its efficiency in recognizing and responding to received DASs. 
     According to still further aspects of the embodiments, to reduce false positives and collocation problems, occupancy indicators can be utilized to determine location and deduce likely commands. For example, once an occupancy sensor determines occupancy in a room and automatically triggers the lights to turn on, the acoustic sensor network can then deduce that an “Off” command is likely to follow in that room. Similarly, other types of occupancy indicators can be combined, such as AV equipment operation, among others. Further, if a command is received by two or more co-located microphones, the occupancy sensors of each of the rooms can be checked, and if one still indicates an occupied room with the lights on, then it is likely the “Off” command was not directed towards it. However, additional processing can be implemented that takes into account time of day, day of the week, additional commands received within specified periods of time (e.g., correcting commands; a first “Off” command followed by a second “Off” command seconds later), among other processes. 
     According to further aspects of the embodiments, additional processing steps can be used to implement additional features. For example, to reduce privacy concerns, the ASN, at start-up, can temporarily employ a remote server to learn the operating environment of the keypad. Once a noise signature of the environment is deduced, the device may use a local processor to filter out background noise and recognize commands. 
     According to further aspects of the embodiments, the ASN, which is part of control network  100  (or which can be a stand-alone network), can reduce background noise to make determination of commands via SRAs more effective. In order to reduce background noise, the ASN can request that certain noise producing devices be turned off in an area where a command is likely to be heard. For example, after detecting lack of occupancy in a bedroom, the ASN can reduce the volume of any audio/video devices that may still be operating, and also reduce heating or air conditioning to the room; this can lower the ambient background noise, and make detection and determination of any commands easier. 
     According to further aspects of the embodiments, the ASN can reduce or eliminate collocation problems. As described above, collation problems are those that related to two or more microphone devices  504  that are relatively close to one another on two separate keypads  106  for different rooms; see, e.g., keypads  106   a ,  106   b , in  FIG. 7  for Jordyn and Nolan&#39;s room. One manner of reducing or substantially eliminating collocation issues, especially in systems that do not utilize zone commands, is to check for occupancy in different rooms/areas. After detecting occupancy in an area or room, the ASN can then disable microphones  504  known to be in adjacent zones (areas/rooms). According to further aspects of the embodiments the ASN can also use occupancy sensor data that shows no-occupancy as a means for reducing or substantially eliminating collocation issues. In this latter case, occupancy sensors from all adjoining rooms are checked against each other; if a room fails to show occupancy, then commands for that room that room would turn off lights are ignored. As those of skill in the art can appreciate, there are numerous variations on how to use occupancy sensor data by the ASN in processing commands to control controllable devices such as lights. 
     According to still further aspects of the embodiments, the SRA of the ASN can recognize characteristic sounds and deduce likely commands to be received in the vicinity. For example, a flushed toilet and running water are likely indicators that a bathroom microphone will receive a “lights off” command. A further example can be a garage door closing, among others. 
     According to still further aspects of the embodiments, the ASN can use voice or speech recognition to identify speakers, learn preferences, and set defaults accordingly. For example, the SAR algorithm of the ASN can recognize that certain individual users prefer certain temperature, humidity, AV, shade, and/or light settings, and set devices at those settings when detecting the user is present. When multiple users are present, the ASN can determine an optimal setting by taking into account each user&#39;s preference. According to still further aspects of the embodiments, when multiple users are present, the ASN can determine an optimum setting by taking into account each user&#39;s preference. 
     Attention is now directed towards  FIG. 8  that illustrates a flow chart of method  800  for determining which controllable device out of a plurality of controllable devices an audible command is directed towards according to aspects of the embodiments. 
     As described herein, an encoding process is discussed in reference to  FIG. 8  and method  800 . The encoding process is not meant to limit the aspects of the embodiments, or to suggest that the aspects of the embodiments should be implemented following the encoding process. The purpose of the following encoding process is to facilitate the understanding of one or more aspects of the embodiments and to provide the reader with one or many possible implementations of the processed discussed herein.  FIG. 8  illustrates a flowchart of various steps performed during the encoding process. The steps of  FIG. 8  are not intended to completely describe the encoding process but only to illustrate some of the aspects discussed above. The encoding process can be further embodied in one or more programs that reside in one or more memory locations of one or more devices, such as, for example, VR SoC circuit  520 , controller  116  and gateway  114 , among other devices. However, in fulfillment of the dual purposes of clarity and brevity, discussion shall be made of method  800  as embodied in audible command processing and determination (ACPD) program  222  (shown in  FIG. 2 ) that resides in memory  206  and can include one or more of AEC, DOA, and DABF processing, as well as SRAs. 
     Method  800  begins with optional method step  802 . Each of the operations of method steps  802 - 810  has been described in greater detail above in regard to  FIGS. 1-7 ; therefore, in fulfillment of the dual purposes of clarity and brevity, a detailed discussion of the same operations and system devices has been omitted from the discussion below of  FIG. 8  and method  800 . In method step  802 , the ASN can be used to learn a user&#39;s speech characteristics in the manner as described above. In addition, method  800  can also acquire information regarding the zones or rooms of a building, office, home, or enterprise location. The latter information can be used to assist in determining which zone or room an audible command is directed towards as described in greater detail below. Method  800  can use the zone/room information to determine the intended “target” of the command by matching control devices to the rooms and zones, and verifying the presence and operational status of the proximity and occupancy sensors, and their locations with regard to each of the rooms and zones. 
     In method step  804 , method  800  receives audio information in the form of an analog signal at one or more microphones  504  at one or more keypads  106  according to aspects of the embodiments. As described in greater detail above, the analog signals are digitized, time and date stamped, can be further processed to substantially eliminate or reduce noise (using AEC, DOA, DABF), and prepared for further processing. The audio signal is now in the form of digital data, or packets, and can be represented as AF n (t), where n ranges from 1 to the total number of keypads  106  that report an audible signal. In decision step  806  of method  800 , each of the received plurality digitized audio signals AF n (t) is analyzed by a speech recognition algorithm (SRA) in ACPD program  222  in order to determine which keypad  106  and controllable devices the audio command signal is directed towards. According to one non-limiting aspect of the embodiments, for example, method  800  (and certain modules of ACPD program  222 ) can be directed to the control of lighting devise; therefore, each command is therefore understandable in the sense that is directed to turning lights on or off, or up or down in intensity, but the question is generally which room or zone is the command directed towards? As those of skill in the art can appreciate, however, the example of method  800  is not limited to lighting devices only, but can be used in controlling a plurality of different devices as has been described herein. With modifications that have been described herein method  800  can be used to control audio-video, HVAC, shading, security, and many other types of devices and/or systems, alone or in combination with each other. These can be embodied in one larger version of ACPD program  222 , or can be embodied in multiple modules of ACPD program  222  as the case may be. 
     If the output of the SRA is of a certainty that exceeds a predetermined threshold of certainty, then method  800  can direct the command to the appropriate device (“Yes” step from decision step  806 ). If the output of the SRA is such that the controllable device of the audio signal cannot be discerned (“No” path from decision step  806 ), then method  800  proceeds to decision step  808 . In decision step  808 , method  800  compares the date-time stamp and magnitude of each of the received AF n (t) signals, presuming there is more than one (if there is only one, then method  800  applies the command to the controllable device to which the control device received the audible signal AF n (t)). According to aspects of the embodiments, the magnitude of the earliest signal should be greater than the magnitude of later arriving signals. Thus, by way of example, if there are two audible signals, AF 1 (t 1 ) and AF 2 (t 2 ), t 1  should be less than t 2 , and the magnitude of AF 1 (t 1 ) should be greater than the magnitude of AF 2 (t 2 ). If this is the case (“Yes” path from decision step  808 ), method  800  proceeds to step  807  and applies the command to the controllable devices associated with the first keypad  106 . The controllable devices of the control device that reports the earliest time-date stamp and greatest magnitude of AF n (t) are the controllable devices to which the command contained in the received AF n (t) signal will be directed towards. In this manner, method  800  takes into account the fact that the speed of sound in a home or office of enterprise location is essentially and substantially constant, and thus the control device that reports the earliest or greatest magnitude audible signal is the one that the command is directed to. If these equalities do not hold true (“No” path from decision step  808 ), then method  800  and ACPD program  222  are directed to decision step  810  for further processing and determinations according to aspects of the embodiments. 
     As those of skill in the art can no doubt now appreciate in view of the discussion above, there are situations and cases where the proscribed process steps  802 - 808  of method  800  might not be enough to discern which controllable device to direct the command to. Thus, in method step  810 , additional parameters/processing/factors can be taken into consideration. As each of these has been described in greater detail above, they will be only briefly discussed again at this point in fulfillment of the dual purposes of clarity and brevity. 
     In method decision step  810 , additional processing can be performed to determine which room or zone or controllable device the received audible signal is directed towards. One, some, or all of the following processing steps/parameters can be taken into account and/or performed, in any particular order, or none can and decision step  800  can terminate with step  808 , as described above. 
     According to still further aspects of the embodiments, a further step that can be taken in decision step  810  alone or in conjunction with one or more of the other processing steps can be to make use of proximity sensors to determine which controllable device the audible signal (command) is directed to. That is, the system and method according to aspects of the embodiments, can use the knowledge of the presence, of lack of presence of a user as determined by one or more proximity sensors can be used to determine which controllable device the command is directed to. This can be accomplished through the use of low/medium power communications protocols such as Bluetooth, NFC, Wi-Fi, among others. According to aspects of the embodiments, a transmitted signal interrogates an electronic device such as PED  104 ; appropriate software located therein received such a transmission, and responds in kind to the proximity sensor. A plurality of proximity sensors can send such location interrogation transmissions. Upon processing all of the responses from each proximity sensor, and determination can be made as to location based on the strength and/or time stamp of the signal transmitted by PED  104  and received by each of the proximity sensors. 
     According to still further aspects of the embodiments, a further step that can be taken in method step  810  alone or in conjunction with one or more of the other processing steps can be to make use of background and/or ambient noise in a passive measure. That is, the system and method according to aspects of the embodiments can use microphones  504  to periodically measure the background of ambient noise levels from time to time and one or more processors, wherever located, can store such readings. These noise levels can then be subtracted from future readings in order to facilitate the presence of commands. As those of skill in the art can appreciate, while such a determination may not in and of itself tell method  800  which controllable device the command is directed to, it can assist in helping to determine when a command has been issued, and in conjunction with other processing steps and/or parameter determinations can be used to determine the nature of the command (e.g., which controllable device in which zone/room the command is directed towards). 
     According to still further aspects of the embodiments, a further step that can be taken in method step  810  alone or in conjunction with one or more of the other processing steps can be to make active use of the occupancy sensor data. That is, the system and method according to aspects of the embodiments can determine the presence or not of a person or persons in a room, and further determine when such person or persons leave the room. Then it can be expected that any ensuing command could be directed towards that room or zone that was just vacated. 
     According to still further aspects of the embodiments, a further step that can be taken in method step  810  alone or in conjunction with one or more of the other processing steps can be to make active use of the output of the occupancy and proximity sensors. That is, the system and method according to aspects of the embodiments can turn off or reduce in volume any “noise” producing devices when occupancy and/or proximity sensors suggest that a room or zone is unoccupied. By reducing the ambient noise level—in this case, noise referring to any audible sound that is not a command (e.g., music, video audio)—the commands, or any commands that might be issued, will become easier to discern, and respond to. 
     According to still further aspects of the embodiments, a further step that can be taken in method step  810 , alone or in conjunction with one or more of the other processing steps, can be to make active use of the output of the occupancy and proximity sensors in another, different manner than that just described. That is, the system and method according to aspects of the embodiments can turn off or disable one or more microphones  504  in one or more rooms or zones when occupancy and/or proximity sensors suggest that a room or zone is unoccupied. By eliminating one or more outputs from microphones  504  in which a command is not expected, the system and method according to aspects of the embodiments will be able to detect with greater accuracy the controllable device that the command is being directed towards. 
     According to still further aspects of the embodiments, a further step that can be taken in method step  810  alone or in conjunction with one or more of the other processing steps can be to make active use of background and/or ambient noises; that is, when certain background or ambient noises occur, the system and method according to aspects of the embodiments can predict future operations based on those noises. Such predictive behavior can be learned over time. By way of non-limiting examples, when a user closes a garage door, for example, a command to turn off the lights in the garage can be expected. Similarly, when a toilet flushes, or running water is turned off in the bathroom sink, the command to turn off the lights in the bathroom can be expected. 
     Once one, some, or all of the above additional processing for ascertaining the correct room to which the received audible command is directed towards are performed, method  800  (ACPD program  222 ) can determine whether, within a certain predefined degree of certainty as to which room the command is directed. If method  800  can make the determination (“Yes” path from decision step  810 ), method  800  proceeds to method step  807  wherein the command is applied to the specified controllable device of the specified room or controlled zone. If, however, after all of the processing of method  800  as embodied as ACPD program  222 , a determination still cannot be made, then no response is provided, and the command is ignored. The user or users can be informed of this by some type of audible, visual, or haptic feedback, or any combination thereof (including all of the feedback methods). 
       FIG. 9  illustrates processing and memory components/circuitry of one or more of the personal electronic device  104  of  FIG. 4 , gateway device  114  of  FIG. 3 , controller  116  of  FIG. 2 , and any other devices that uses one or more processors as described herein that uses software and/or applications to perform various functions and actions as described herein according to aspects of the embodiments. 
       FIG. 9  illustrates processing and memory components/circuitry (generally referred to as a “computer” or personal computer (PC)) of one or more of the personal electronic device  104  of  FIG. 4 , gateway device  114  of  FIG. 3 , controller  116  of  FIG. 2 , and any other devices that uses one or more processors as described herein that uses or runs or implements software and/or applications, such as the configuration application, project files, or control applications, to perform various functions and actions as described herein according to aspects of the embodiments, suitable for use to implement method  800  for determining which controllable device an audible command is directed towards according to an embodiment. 
     PC  900  comprises, among other items, integrated display/touch-screen  902  (though not used in every application of PC  900 ), internal data/command bus (bus)  904 , processor board/PC internal memory (internal memory)  932 , and one or more processors  908  with processor internal memory  906  (which can be typically read only memory (ROM) and/or RAM). Those of ordinary skill in the art can appreciate that in modern PC systems, parallel processing is becoming increasingly prevalent, and whereas a single processor would have been used in the past to implement many or at least several functions, it is more common currently to have a single dedicated processor for certain functions (e.g., digital signal processors) and therefore could be several processors, acting in serial and/or parallel, as required by the specific application. PC  900  further comprises multiple input/output ports, such as universal serial bus ports  910 , Ethernet ports  911 , and video graphics array (VGA) ports/high definition multimedia interface (HDMI) ports  922 , among other types. Further, PC  900  includes externally accessible drives such as compact disk (CD)/digital video disk (DVD) read/write (RW) (CD/DVD/RW) drive  912 , and floppy diskette drive  914  (though less used currently, many PCs still include this device). 
     Internal memory  932  itself can comprise hard disk drive (HDD)  916  (these can include conventional magnetic storage media, but, as is becoming increasingly more prevalent, can include flash drive memory  934 , among other types), read-only memory (ROM)  918  (these can include electrically erasable (EE) programmable ROM (EEPROMs), ultra-violet erasable PROMs (UVPROMs), among other types), and RAM  920 . Usable with USB port  910  is flash drive memory  934 , and usable with CD/DVD/RW drive  912  are CD/DVD disks  936  (which can be both read and write-able). Usable with floppy diskette drive  914  are floppy diskettes  938 . External memory storage  924  can be used to store data and programs external to box  901  of PC  900 , and can itself comprise another hard disk drive  916   a , flash drive memory  934 , among other types of memory storage. External memory storage  924  is connectable to PC  900  via USB cable  956 . Each of the memory storage devices, or the memory storage media ( 906 ,  916 ,  918 ,  920 ,  924 ,  934 ,  936 , and  938 , among others), can contain parts or components, or in its entirety, executable software programming code or application (application, or “App”), such as ACPD program  222 , which can implement part or all of the portions of method  800  described herein. 
     Bus  904  provides a data/command pathway for items such as: the transfer and storage of data/commands between processor  908 , integrated display  902 , USB port  910 , Ethernet port  911 , VGA/HDMI port  922 , CD/DVD/RW drive  912 , floppy diskette drive  914 , and internal memory  932 . Through bus  904 , data can be accessed that is stored in internal memory  932 . Processor  908  can send information for visual display to either or both of integrated and external displays, and the user can send commands to system operating programs/software/Apps  940  that might reside in processor internal memory  906  of processor  908 , or any of the other memory devices ( 936 ,  938 ,  916 ,  918 , and  920 ). 
     PC  900 , and either processor internal memory  906  or internal memory  932 , can be used to implement method  800  for determining which controllable device an audible command is directed towards according to an embodiment. Hardware, firmware, software or a combination thereof can be used to perform the various steps and operations described herein. According to an embodiment, App  940  for carrying out the above discussed steps can be stored and distributed on multi-media storage devices such as devices  916 ,  918 ,  920 ,  934 ,  936  and/or  938  (described above) or other form of media capable of portably storing information. Storage media  934 ,  936  and/or  938  can be inserted into, and read by devices such as USB port  910 , CD/DVD/RW drive  912 , and disk drives  914 , respectively. 
     As also will be appreciated by one skilled in the art, the various functional aspects of the embodiments may be embodied in a wireless communication device, a telecommunication network, or as a method or in a computer program product. Accordingly, the embodiments may take the form of an entirely hardware embodiment or an embodiment combining hardware and software aspects. Further, the embodiments may take the form of a computer program product stored on a computer-readable storage medium having computer-readable instructions embodied in the medium. Any suitable computer-readable medium may be utilized, including hard disks, CD-ROMs, digital versatile discs (DVDs), optical storage devices, or magnetic storage devices such a floppy disk or magnetic tape. Other non-limiting examples of computer-readable media include flash-type memories or other known types of memories. 
     Further, those of ordinary skill in the art in the field of the embodiments can appreciate that such functionality can be designed into various types of circuitry, including, but not limited to field programmable gate array structures (FPGAs), application specific integrated circuitry (ASICs), microprocessor based systems, among other types. A detailed discussion of the various types of physical circuit implementations does not substantively aid in an understanding of the embodiments, and as such has been omitted for the dual purposes of brevity and clarity. However, as well known to those of ordinary skill in the art, the systems and methods discussed herein can be implemented as discussed, and can further include programmable devices. 
     Such programmable devices and/or other types of circuitry as previously discussed can include a processing unit, a system memory, and a system bus that couples various system components including the system memory to the processing unit. The system bus can be any of several types of bus structures including a memory bus or memory controller, a peripheral bus, and a local bus using any of a variety of bus architectures. Furthermore, various types of computer readable media can be used to store programmable instructions. Computer readable media can be any available media that can be accessed by the processing unit. By way of example, and not limitation, computer readable media can comprise computer storage media and communication media. Computer storage media includes volatile and nonvolatile as well as removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Computer storage media includes, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CDROM, digital versatile disks (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and which can be accessed by the processing unit. Communication media can embody computer readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave or other transport mechanism and can include any suitable information delivery media. 
     The system memory can include computer storage media in the form of volatile and/or nonvolatile memory such as ROM and/or RAM. A basic input/output system (BIOS), containing the basic routines that help to transfer information between elements connected to and between the processor, such as during start-up, can be stored in memory. The memory can also contain data and/or program modules that are immediately accessible to and/or presently being operated on by the processing unit. By way of non-limiting example, the memory can also include an operating system, application programs, other program modules, and program data. 
     The processor can also include other removable/non-removable and volatile/nonvolatile computer storage media. For example, the processor can access a hard disk drive that reads-from or writes-to non-removable, nonvolatile magnetic media, a magnetic disk drive that reads from or writes to a removable, nonvolatile magnetic disk, and/or an optical disk drive that reads from or writes to a removable, nonvolatile optical disk, such as a CD-ROM or other optical media. Other removable/non-removable, volatile/nonvolatile computer storage media that can be used in the operating environment include, but are not limited to, magnetic tape cassettes, flash memory cards, digital versatile disks, digital video tape, solid state RAM, solid state ROM and the like. A hard disk drive can be connected to the system bus through a non-removable memory interface such as an interface, and a magnetic disk drive or optical disk drive can be connected to the system bus by a removable memory interface, such as an interface. 
     The embodiments discussed herein can also be embodied as computer-readable codes on a computer-readable medium. The computer-readable medium can include a computer-readable recording medium and a computer-readable transmission medium. The computer-readable recording medium is any data storage device that can store data which can be thereafter read by a computer system. Examples of the computer-readable recording medium include ROM, RAM, CD-ROMs and generally optical data storage devices, magnetic tapes, flash drives, and floppy disks. The computer-readable recording medium can also be distributed over network coupled computer systems so that the computer-readable code is stored and executed in a distributed fashion. The computer-readable transmission medium can transmit carrier waves or signals (e.g., wired or wireless data transmission through the Internet). Also, functional programs, codes, and code segments to, when implemented in suitable electronic hardware, accomplish or support exercising certain elements of the appended claims can be readily construed by programmers skilled in the art to which the embodiments pertain.
