     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to a portable electronic device and, more particularly, to a multi-function portable electronic device. 
     Description of the Related Art 
     Today, cellular phones primarily require manual interaction by a user to invoke functions or to enter data, etc. However, cellular phones can also support limited voice activation. For example, a user can press a predetermined button, then speak a name of a person in the address book of the cellular phone. If the cellular phone recognizes the spoken name, then the person can be automatically called using the phone number provided in the address book. Cellular phones can also be use inside automobiles in a similar fashion. Some automobiles also support hands-free cellular operation by providing an embedded speaker and microphone internal to the vehicle. Bluetooth car kits are also available to add-on a speaker and microphone for hands-free operation. In any case, with cellular phones, voice commands are also conventionally limited to recognizing names of contacts within an address book and require manual user interaction with the cellular phone or automobile (e.g., button press) prior to any voice command. 
     Specialized computer programs also exist which can execute on a personal computer and wirelessly interact with a Bluetooth-enabled cellular phone. For example, a user interface displayed on a personal computer can allow a user to dial, answer, hang up and hold calls with respect to a cellular phone. Users can also be alerted at the personal computer of incoming calls or SMS messages. When a call is received at the cellular phone, media playback in progress at the personal computer can be paused.

The AC power, when available, is also used to charge battery  224 . 
       FIG.  3    is a block diagram of voice-to-command analyzer  300  according to one embodiment of the invention. Voice-to-command analyzer  300  is, for example, one implementation of voice-to-command analyzer  216  illustrated in  FIG.  2   . Voice-to-command analyzer  300  receives a voice input from a microphone (e.g., microphone  218 ). Voice-to-command analyzer  300  also receives data pertaining to available commands. For example, the available commands can be stored and accessed in a data store, such as data store  220  illustrated in  FIG.  2   . In addition, voice-to-command analyzer  300  can receive device state information. The device state information can provide voice-to-command analyzer  300  with information concerning the state of the electronic device (e.g., device  200 ). The device state information can, for example, pertain to a state, condition, event or the like, which can pertain to hardware or software. 
     As an example, one state associated with the electronic device having voice-to-command analyzer  300  is a context of a graphical user interface (GUI) utilized by the electronic device. The context of the GUI can then provide state information to the voice-to-command analyzer  300 . In one embodiment, depending upon the context of the GUI, different available commands can be utilized and provided to the voice-to-command analyzer  300 . In general, as the device state changes, different available commands can be presented to voice-to-command analyzer  300 . As a result, the available commands being provided to voice-to-command analyzer  300  can be restricted to those that are appropriate given the current state of the electronic device. Eventually, the voice-to-command analyzer  300  can recognize a command from the voice input. The recognized command is one of the available commands presented to voice-to-command analyzer  300 . Of course, the voice input may not correlate to any of the available commands, in which case voice-to-command analyzer  300  would not output a recognized command. 
       FIG.  4    is a flow diagram of voice command process  400  according to one embodiment of the invention. Voice command process  400  is, for example, performed by an electronic device, such as device  100  illustrated in  FIG.  1    or device  200  illustrated in  FIG.  2   . 
     Voice command process  400  monitors  402  an operational state of a portable electronic device. For example, the operational state may correspond to a functional mode, usage or program being utilized by the portable electronic device. As another example, the operational state can pertain to a state of a graphical user interface being provided on a display associated with the portable electronic device. 
     The voice command process  400  also receives  404  an audio input. Here, the portable electronic device includes electrical components that enable the portable electronic device to receive  404  an audio input. Typically, the audio input is a voice input provided by a user of the portable electronic device. 
     Next, a set of commands that are authorized for usage with the portable electronic device while in the operational state can be determined  406 . Then, the voice command process  400  can determines  408  whether the audio input pertains to at least one of the commands within the set of commands. Since the determination  408  is limited, in one embodiment, to those commands within the set of commands that are authorized for usage while in the operational state, the determination  408  can be rapidly performed without excessive computational capability and without excessive power consumption. Thereafter, the at least one of the commands within the set of commands that has been determined  408  to pertain to the audio input can be executed  410 . Consequently, voice command process  400  receives an audio input from a user, determines which of the limited set of available commands the user is requesting by the audio input, and then executes the appropriate command. Accordingly, an electronic device using voice command process  400  is able to command or control the operation of the electronic device using voice, namely, the electronic device is voice activated. 
       FIG.  5    is a flow diagram of voice command process  500  according to another embodiment of the invention. Voice command process  500  is, for example, performed by an electronic device, such as device  100  illustrated in  FIG.  1    or device  200  illustrated in  FIG.  2   . 
     The voice command process  500  activates  502  a microphone. The device is also operated  504  in a low power mode if appropriate. For example, if the device is substantially idle and no user input is being received, the electronic device can be placed in a low power mode to conserve battery energy. Decision  506  determines whether an audio pickup has been received. The device can receive an audio pickup even while in the low power mode. When decision  506  determines that an audio pickup has not been received, voice command process  500  awaits to receive an audio pickup. Once the decision  506  determines that an audio pickup has been received, the audio pickup is analyzed  508 . When analyzing the audio pickup, the processing can be made efficient and more robust by taking into consideration context with which the audio pickup has been received. The context can pertain to the electronic device, such as a state of the electronic device. In other words, the audio pickup can be analyzed  508  in a context-sensitive manner. 
     Next, decision  510  determines whether a voice command has been recognized. When decision  510  determines that a voice command has not recognized, voice command process  500  returns to repeat decision  506  to subsequently process another audio pickup. On the other hand, when decision  510  determines that a voice command has been recognized, the electronic device is operated  512  in a normal power mode. Here, if the electronic device was in a low power mode, the electronic device is returned to a normal power mode so that the recognized voice command can be quickly and efficiently processed. 
     In this embodiment, the recognized command can pertain to a macro. Decision  514  determines whether the recognized command is a macro. When the recognized command is not a macro, the recognized command is executed  516 . On the other hand, when decision  514  determines that the command is a macro, the associated macro is retrieved  518 . The associated macro is then executed  520 . Decision  522  then determines whether there is any more operations (e.g., commands) within the associated macro that is to be executed. When decision  522  determines that there are more operations to be executed, voice command process  500  returns to repeat block  520  so that additional operations of the associated macro can be executed. Once decision  522  determines that there are no more operations within the macro to be executed, as well as directly following the block  516 , voice command process  500  returns to repeat block  502  and subsequent operations so that a subsequent audio pickup can be processed in a similar manner. 
       FIG.  6    is a flow diagram of a voice command recognition process  600  according to one embodiment of the invention. The voice command recognition process  600  can, for example, pertain to processing associated with the decision  510  illustrated in  FIG.  5   . In other words, the voice command recognition process operates to determine whether the audio pickup pertains to one of the available commands supported by an electronic device. In particular, the voice command recognition process  600  can determine  602  a device context. Those commands available given the device context can then be identified  604 . The audio pickup can be correlated  606  to the identified commands. Thereafter, the voice command recognition process  600  determines  608  whether the audio pickup corresponds to one of the identified commands based on the correlation data. 
     One aspect of the invention pertains restricting available commands based on device context. The device context, in one embodiment, pertains to the state of a graphical user interface (GUI).  FIGS.  7 A- 7 C  illustrate exemplary graphical user interfaces that can be presented on a display device according to certain embodiment of the invention. These exemplary graphical user interfaces are just a few of the many embodiments that can utilize state of GUI to restrict or limit available voice commands to be recognized. 
       FIG.  7 A  illustrates exemplary menu  700  suitable for use on a display device associated with an electronic device according to one embodiment of the invention. While menu  700  is being displayed, a user can provide an audio input that pertains to a voice command. When menu  700  is displayed, the available voice commands that can received can be restricted. The menu  700  can be used to navigate to an appropriate media item or a group of media items to be played by the electronic device. While menu  700  is being displayed, a user can request to play a particular media item. For example, the user might provide an audio input, namely, a voice command, by announcing the phrase “play irreplaceable”. Here, the electronic device would recognize that the first portion “play” is a command that is supported and the second term “irreplaceable” is the name of a song available to be played at the electronic device. As another example, the user could provide an audio input, namely, a voice command, by announcing the phrase “play 06”, which could be the user requesting to play a playlist denoted as “summer &#39;06” and available at the media device. As still another example, the user could provide an audio input, namely, a voice command, by announcing one of the menu items of the menu  700  (or perhaps even a nested menu) which could effect a selection of such item. For example, the menu items could be categories, classifications, groupings, media items, device settings, device functions, and the like. The menu  700  can represent one menu of a series of nested or hierarchical menus, which can also be navigated or traversed by voice commands. 
       FIG.  7 B  illustrates display region  720  of a display device associated with an electronic device according to one embodiment of the invention. Display region  720  includes meeting reminder notification  722 . Meeting reminder notification  722  can be displayed on at least a portion of display region  720 . In this example, meeting reminder notification  722  informs the user that a meeting to which they are scheduled starts in “15 minutes” at building “IL1, Room 1.” In this context, the available commands available to the user can pertain to permitted interaction with the electronic device in response to the meeting reminder. For example, the acceptable commands can be “clear” or “close” which requests that the electronic device close meeting reminder notification  722 . Another example is the command “tell” which can respond to the meeting attendees with a message. For example, “tell everyone I will be 10 minutes late” which will be understood by the electronic device as a request to send a text message or email to all attendees of the meeting that the user will be ten (10) minutes late to the meeting. 
       FIG.  7 C  is an illustration of exemplary camera window  740  of a display device associated with an electronic device according to one embodiment of the invention. Camera window  740  can be presented on a display device associated with the electronic device. Camera window  740  is displayed on the display device when the electronic device has been placed in a camera mode. While in the camera mode, the available commands can be specific to likely camera operations. For example, in the camera mode, likely camera operations include taking pictures, deleting pictures, saving pictures, etc. Available commands in the camera mode can also include macros. As an example, a macro can be triggered when an audio input is a command requesting that a current picture be taken. As an example, a macro can cause the picture to be taken, cause the picture to be saved in memory, and cause the picture to be uploaded. Although the electronic device is voice-activated, in some embodiments, the electronic device also supports the use of non-voice-activated techniques to provide user input. For example, camera window  740  can include soft buttons  742 - 746  for which the user can provide user input. Soft buttons  742 - 746  can be activated using a keypad.

     According to one aspect of the invention, a portable electronic device can interact with a media system. The interaction can be provided via a direct connection, a wired connection to a network, or a wireless connection to a network. 
       FIG.  10    illustrates process  1000  involving interaction between a portable electronic device and a media system according to one embodiment of the invention. In this embodiment, the context of the interaction is such that the media system is playing media using media data provided by the portable electronic device, while also answering a telephone call at the portable electronic device. 
     Process  1000  is a representative process that can be utilized between a portable electronic device and a media system according to one embodiment of the invention. At step  1 , media to be played on the media system can be selected. A play command and the media data can then be sent to the media system (step  2 ). At the media system, the play command and the media data can be received and then the play command executed (step  3 ). Hence, media corresponding to the media data is output (step  4 ). Here, in this embodiment, the media data for the media to be played is provided by the portable electronic device to the media system. In another embodiment, the media data could be resident on the media system and when the play command is executed, the media could be output from the media data resident on a media system. 
     At some time later, assuming that the media is still being output, an incoming call can be detected (step  5 ). When an incoming call is detected (step  5 ), a ringtone command can be sent to the media system (step  6 ). The media system can subsequently receive and execute the ringtone command (step  7 ) when the ringtone command is executed, a ringtone is output (step  8 ). At the portable electronic device, when the ringtone is output (step  8 ), the user of the portable electronic device understands that there is an incoming call that can be answered. It should be understood that the ringtone could also be output directly at the portable electronic device. However, one advantage of outputting the ringtone by the media system is that the media being output by the media system can also continue to be output in a manner such that the ringtone can still be heard. For example, when outputting the ringtone, the output of the media (step  4 ) could have its volume lowered. In any case, at step  9 , it is determined whether the user desires to answer the call. In this embodiment, it is assumed that the user will signal the portable electronic device using a voice command. Alternatively, the user can signal the portable electronic device to answer the call through a physical selection (e.g., button press). Hence, when the user has signaled to answer the call by a voice command, an answer call command will be executed (step  10 ). Since the call is being answered, a pause media command can be sent to the media system (step  11 ). The media system then receives and executes the pause media command (step  12 ). In doing so, media output is paused (step  13 ). Then, the user participates in the call and at some time later determines to end the call (step  14 ). Again, the determination to end the call can be done in a voice-activated manner. Alternatively, the end of the call can be initiated through a physical selection (e.g., button press). In any case, when the determination is made to end the call (step  14 ), the call is ended (step  15 ). A resume media command can then be sent to the media system (step  16 ). At the media system, the resume media command can be received and executed (step  17 ). The media output is then resumed (step  18 ). 
       FIGS.  11 A and  11 B  are flow diagrams of process  1100  according to one embodiment of the invention. Process  1100  concerns media playback and voice call handling. In one example, process  1100  can be performed by a portable electronic device supporting wireless voice communications and media playback. In another example, process  1100  can be performed by a portable electronic device supporting wireless voice communications and a media system providing media playback. 
     Process  1100  can begin with decision  1102  that determines whether a call is incoming. When decision  1102  determines that a call is not incoming, process  1100  waits for an incoming call. On the other hand, when decision  1102  determines that a call is incoming, decision  1104  determines whether media playback is active. When decision  1104  determines that media playback is not active a ringtone can be output  1106 . Alternatively, when decision  1104  determines that media playback is active, the volume of the media output can be limited  1108 . Also, a ringtone mixed with the media output can be output  1110 . Following block  1106  or block  1110 , a microphone can be activated  1112 . 
     Next, decision  1114  determines whether a voice command has been received. When decision  1114  determines that a voice command has not been received, decision  1116  determines whether a time-out has occurred. The time-out refers to a predetermined period of time during which the user of the electronic device can answer the incoming call. During this period of time, the microphone is activated so that a voice command can be received. When decision  1116  determines that a time-out has not yet occurred, process  1100  returns to repeat decision  1114  to continue to determine whether a voice command has been received. When decision  1114  determines that a voice command has been received, decision  1118  can determine whether a “who is it” command has been received. The “who is it” command is one type of voice command that can be received. When decision  1118  determines that a “who is it” command has been received, then caller information can be presented  1120 . Presentation  1120  of caller information can be performed using a display device and/or by audio output. Following block  1120 , process  1100  returns to repeat decision  1114  and subsequent blocks. 
     On the other hand, when decision  1118  determines that the voice command received is not a “who is it” command, decision  1122  determines whether the voice command is an answer call command. When decision  1122  determines that the voice command is not an answer call command, decision  1124  determines whether a call is to be manually answered. When decision  1124  determines that the call is not to be manually answered, then process  1100  returns to repeat decision  1114 . Alternatively, when decision  1122  determines that the voice command received is an answer call command, as well as following decision  1124  when the call is to be manually answered, the media playback is paused  1126 . By pausing the media playback, the user of the electronic device is able to participate in the call without being disturbed by the media playback. In another embodiment, the media playback can continue with its volume substantially limited such that it is does not materially interfere with the ability of the user to participate in the call. The incoming call is also answered  1128 . Audio input/output for the call can then be processed  1130 . 
     As the call continues, audio pertaining to the call will be incoming and outgoing so as to carry out the conversation or communications associated with the call. Decision  1132  can determine during the call whether a voice command has been received. Here, during the call, the electronic device can render certain commands as being available to be voice-activated by a user. When decision  1132  determines that a voice command has been received, decision  1134  determines whether the voice command is an end call command. The end call command is one type of voice command that can be received. When decision  1134  determines that the voice command that has been received is not an end call command, then optionally other commands can be processed  1136 . Alternatively, when decision  1132  determines that a voice command has not been received, as well as following block  1136 , decision  1138  determines whether a call is to end. Here, the call can be ended by a manual operation with respect to the electronic device. In other words, decision  1138  is a manual operation that is distinct from a voice command. When decision  1138  determines that the call is not to end, process  1100  returns to repeat block  1130  and subsequent blocks. Alternatively, when decision  1138  determines that the call is to end manually, or when decision  1134  determines that the received voice command is an end call command, then the call is closed  1140 . Further, the microphone is deactivated  1142 . In addition, playback of the media can be resumed  1144 . Also, when decision  1116  determines that a time-out has occurred, the microphone can also be deactivated  1148 . Following block  1148  or block  1144 , the media output can be returned  1146  to its prior volume level. Following block  1146 , process  1100  can end. 
     The media playback and voice call handling discussed above in  FIGS.  10 ,  11 A and  11 B  are examples of control of a media system by way of voice commands provided at a portable electronic device (or an associated accessory device). More generally, according to one embodiment of the invention, a media system can be controlled in any of a number of ways by voice commands provided at a portable electronic device (or an associated accessory device). For example, a user of the portable electronic device can provide voice comments that cause the media system to perform a channel change, a mute operation, media source change, track change, playback operation, stop playback, volume adjustment, etc. 
     The electronic device as described herein can be a wireless communication device (e.g., portable telephone) capable of communication over a network. The wireless communication device can also include other applications such as a media playback application or a media recording application. 
     The electronic device as described herein can be a media device (e.g., media player) capable of playing (including displaying) media items. The media items can pertain to audio items (e.g., audio files or songs), videos (e.g., movies) or images (e.g., photos). The media device can also include other applications such as a wireless communication application. 
     In one embodiment, the electronic device is a portable electronic device. In one implementation, the portable electronic device is a handheld electronic device. Often, portable electronic devices are handheld electronic devices that can be easily held by and within a single hand of a user. The portable electronic device can also pertain to a wearable electronic device or a miniature electronic device. However, the invention can apply to electronic devices whether portable or not. 
       FIG.  12    is a block diagram of media player  1200  according to one embodiment of the invention. Media player  1200  can include the circuitry of device  100  in  FIG.  1   , device  200  in  FIG.  2   , device  900  in  FIGS.  9 A- 9 C , device  952  in  FIG.  9 D , or can perform the operations described with reference to  FIG.  4 - 6 ,  10  or  11 A and  11 B , and/or can present a display screen as in  FIGS.  7 A- 7 C  or  FIGS.  8 A- 8 D . 
     Media player  1200  can include processor  1202  that pertains to a microprocessor or controller for controlling the overall operation of media player  1200 . Media player  1200  can store media data pertaining to media items in file system  1204  and cache  1206 . File system  1204  is, typically, a storage disk or a plurality of disks. File system  1204  typically provides high capacity storage capability for media player  1200 . File system  1204  can store not only media data but also non-media data. However, since the access time to file system  1204  is relatively slow, media player  1200  can also include cache  1206 . Cache  1206  is, for example, Random-Access Memory (RAM) provided by semiconductor memory. The relative access time to cache  1206  can be substantially shorter than for file system  1204 . However, cache  1206  does not have the large storage capacity of file system  1204 . Further, file system  1204 , when active, consumes more power than does cache  1206 . The power consumption is often a concern when media player  1200  is a portable media player that is powered by battery  1207 . Media player  1200  can also include RAM  1220  and Read-Only Memory (ROM)  1222 . ROM  1222  can store programs, utilities or processes to be executed in a non-volatile manner. RAM  1220  provides volatile data storage, such as for cache  1206 . 
     Media player  1200  can also include user input device  1208  that allows a user of media player  1200  to interact with media player  1200 . For example, user input device  1208  can take a variety of forms, such as a button, keypad, dial, etc. (physical or soft implementations) each of which can be programmed to individually or in combination perform any of a suite of functions. In one implementation, user input device  1208  can be provided by a dial that physically rotates. In another implementation, user input device  1208  can be implemented as a touchpad (i.e., a touch-sensitive surface). In still another implementation, user input device  1208  can be implemented as a combination of one or more physical buttons as well as a touchpad. Still further, media player  1200  can include display  1210  (screen display) that can be controlled by processor  1202  to display information to the user. Data bus  1211  can facilitate data transfer between at least file system  1204 , cache  1206 , processor  1202 , and CODEC  1212 . 
     Media player  1200  can also provide status monitoring of battery  1207 . In this regard, media player  1200  can include battery monitor  1213 . Battery monitor  1213  can be operatively coupled to battery  1207  to monitor conditions. Battery monitor  1213  can, for example, communicate battery status (or conditions) with processor  1202 . 
     In one embodiment, media player  1200  can serve to store a plurality of media items (e.g., songs, videos, TV shows, podcasts, etc.) in file system  1204 . When a user desires to have media player  1200  play a particular media item, a list of available media items can be displayed on display  1210 . Then, using user input device  1208  (or voice commands), a user can select one of the available media items. Processor  1202 , upon receiving a selection of a particular media item, can supply the media data (e.g., audio file) for the particular media item to coder/decoder (CODEC)  1212 . CODEC  1212  can then produce analog output signals for speaker  1214 . Speaker  1214  can be a speaker internal to media player  1200  or external to media player  1200 . For example, headphones or earphones that connect to media player  1200  could be considered an external speaker. Speaker  1214  can not only be used to output audio sounds pertaining to the media item being played, but also to output audio notifications pertaining to battery status. Notifications of battery status can also be output to display  1210 . 
     In one embodiment, media player  1200  is a portable computing device that can support processing media, such as audio and/or video. For example, media player  1200  can be a music player (e.g., MP3 player), a video player, a game player, and the like. These devices are generally battery operated and highly portable so as to allow a user to listen to music, play games or video, record video or take pictures wherever the user travels. 
     In one implementation, media player  1200  is a handheld device sized for placement into a pocket or hand of the user. By being handheld, media player  1200  is relatively small and easily handled and utilized by its user. By being pocket sized, the user does not have to directly carry the device and therefore the device can be taken almost anywhere the user travels (e.g., the user is not limited by carrying a large, bulky and often heavy device, as in a portable computer). Furthermore, in one implementation, the device may be operated by the user&#39;s hands; no reference surface such as a desktop is needed. 
     Media player  1200  can also include network/bus interface  1216  that couples to data link  1218 . Data link  1218  can allow media player  1200  to couple to a host computer. Datalink  1218  can be provided over a wired connection or a wireless connection. In the case of a wireless connection, network/bus interface  1216  can include a wireless transceiver. 
     To support wireless communications, media player  1200  can also include wireless communications module  1224 . Wireless communication module  1224  can be considered to provide voice communications (e.g., calls via a cellular network), whereas network/bus interface  1216  can be considered to provide data communications. A user of media player  1200  can thus make and receive voice calls using the wireless communications module in media player  1200 . Wireless communications module  1224  can also couple to data bus  1211  to couple to processor  1202  and other resources. Media player  1200  can also include microphone  1226  for pick up of the user&#39;s voice. 
     The invention is suitable for use with battery-powered electronic devices. However, the invention is particularly well suited for handheld electronic devices, such as a handheld media device. One example of a handheld media device is a portable media player (e.g., music player or MP3 player). Another example of a handheld media device is a mobile telephone (e.g., cell phone) or Personal Digital Assistant (PDA). 
     Portable media devices can store and play audio sounds pertaining to media assets (media items), such as music, audiobooks, meeting recordings, and other speech or voice recordings. Portable media devices, such as media players, are small and highly portable and have limited processing resources. Often, portable media devices are handheld media devices which can be easily held by and within a single hand of a user. 
     One example of a media player is the iPod® media player, which is available from Apple Inc. of Cupertino, CA Often, a media player acquires its media assets from a host computer that serves to enable a user to manage media assets. As an example, the host computer can execute a media management application to utilize and manage media assets. One example of a media management application is iTunes®, produced by Apple Inc. 
     “Media items,” as used herein, is digital data that pertains to at least one of audio, video, or images. Media items are also referred to as digital media assets. The digital data for media items can be referred to as media data or media content. Some examples of specific forms of media items include, but are not limited to, songs, albums, audiobooks, playlists, movies, music videos, photos, computer games, podcasts, audio and/or video presentations, news reports, and sports updates. Video media items include movies, music videos, video presentations, and any other media items having a video characteristic.

     The various aspects, embodiments, implementations or features of the invention can be used separately or in any combination. 
     The invention is preferably implemented by software, hardware or a combination of hardware and software. The invention can also be embodied as computer readable code on a computer readable medium. The computer readable medium is any data storage device that can store data which can thereafter be read by a computer system. Examples of the computer readable medium include read-only memory, random-access memory, CD-ROMs, DVDs, magnetic tape, optical data storage devices, and carrier waves. The computer readable 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 advantages of the invention are numerous. Different aspects, embodiments or implementations may, but need not, yield one or more of the following advantages. One advantage of the invention is that an electronic device can be user controlled through voice commands. Another advantage of the invention is that available voice commands can be context sensitive for robust and power efficient operation. Yet another advantage of the invention is that an electronic device can intelligently interact with a nearby media system to provide multiple functions (e.g., media playback and wireless voice communications). 
     The many features and advantages of the present invention are apparent from the written description. Further, since numerous modifications and changes will readily occur to those skilled in the art, the invention should not be limited to the exact construction and operation as illustrated and described. Hence, all suitable modifications and equivalents may be resorted to as falling within the scope of the invention.
