## Background
PRIORITY
The present patent application is a continuation-in-part (CIP) of co-pending U.S. patent application Ser. No. 14/854,927 filed Sep. 15, 2015 and entitled “System for Voice Capture via Nasal Vibration Sensing.” The entire contents of the above-identified U.S. patent application are incorporated herein by reference.


TECHNICAL FIELD
The present disclosure relates to electronic communication, and more particularly, to a system for capturing a user's voice and generating sound for the user utilizing nasal resonation.
BACKGROUND
Electronic communication has become an integral part of modern society. For example, people may rely on mobile communications for business and/or personal interaction, to conduct financial transactions, to query for a variety of different data, for location-related assistance, to play games or watch multimedia presentations, etc. The expansion of various wireless networks such as global-area networks (GANs), wide-area networks (WANs) like the Internet, local-area networks (LANs), personal-area networks (PANs), etc., has further facilitated users in being able to perform even more activities on their mobile device in even more locations. Now users may be able to make calls, access the Internet, execute financial transactions, etc. while operating a motor vehicle, riding on public transportation, at work, at school, at home, at a public event, etc.
While the benefits of the above are readily apparent, possibly negative consequences may also exist. There are currently active campaigns against utilizing mobile devices while operating a motor vehicle. The operation of a mobile device when driving may divert the driver's attention away from the road and cause accidents. Moreover, it can be difficult to operate a mobile device at public events due to environmental noise. These problematic situations may be alleviated by the advent of “hands free” peripheral equipment. Hands free peripheral equipment may provide interfaces over which a user may interact with a mobile device that remains stored, in a charger, etc. This interaction may take place over a wired or wireless communication link. Examples of hands free peripheral equipment may include, but are not limited to, speakerphones, headsets, microphones, remote controls, etc. While these devices may be helpful, they are not all-purpose fixes. For example, headsets may facilitate hands-free communication, but may also experience problems in certain noisy situations. Wearing a headset also requires a user to maintain another device that they would not normally wear unless hands-free operations was desired or required, and in some regions wearing a headset (e.g., earpiece) may have negative stylistic implications.

DETAILED DESCRIPTION
The present disclosure pertains to a system for voice capture via nasal vibration sensing. A system worn by a user may be able to sense vibrations through the nose of the user when the user speaks, generate an electronic signal based on the sensed vibration and generate voice data based on the electronic signal. In this manner, the system may capture a user's voice for use in, for example, dictation, telephonic communications, etc., while also screening out external noise (e.g., based on the natural sound dampening properties of the human skull). An example system may include a wearable frame (e.g., an eyeglass frame) on which is mounted at least one sensor and a device. The at least one sensor may sense vibration in the nose of a user and may generate the electronic signal based on the vibration. The device may receive the electronic signal from the at least one sensor and may generate voice data based on the electronic signal. Other features may include, for example, compensation for situations where vibration cannot be sensed, sound generation based on received audio data for use in, for example, telephonic communications, etc.
In at least one embodiment, an example system to capture a voice of a user may comprise at least a frame, at least one sensor mounted to the frame and a device mounted to the frame. The frame may be wearable by a user. The at least one sensor may be to generate an electronic signal based on vibration sensed in a nose of the user when the user talks. The device may be to at least receive the electronic signal from the at least one sensor and process the electronic signal to generate voice data.
The frame may be for eyeglasses. In this example implementation the at least one sensor may be incorporated within at least one nosepiece for the eyeglasses. It may also be possible for two sensors to be embedded in two sides of the nosepiece. For example, the two sensors may be coupled in series and the device is to receive a combined electronic signal generated by the two sensors. Alternatively, the device may be to select to process the electronic signal generated from one of the two sensors.
The at least one sensor may comprise a piezoelectric diaphragm to generate the electronic signal. The device may comprise at least control circuitry to generate the voice data from the electronic signal. The control circuitry may also be to determine whether the voice data includes a local command, and if determined to include a local command, perform at least one activity based on the local command. The device may also comprise at least communication circuitry to transmit the voice data to an external device and at least user interface circuitry to allow the user to interact with the system. In at least one embodiment, the user interface circuitry is to generate sound based on audio data received from the external device via the communication circuitry. Consistent with the present disclosure, an example method for capturing voice data from a user may comprise activating sensing for nasal vibration in a wearable system, sensing nasal vibration with at least one sensor in the wearable system, generating an electronic signal based on the nasal vibration and generating voice data based on the electronic signal.
FIG. 1 illustrates an example system 100 for voice capture via nasal vibration sensing in accordance with at least one embodiment of the present disclosure. While examples of specific implementations (e.g., in eyeglasses) and/or technologies (e.g., piezoelectric sensors, Bluetooth wireless communications, etc.) will be employed herein, these examples are presented merely to provide a readily comprehensible perspective from which the more generalized devices, systems, methods, etc. taught herein may be understood. Other applications, configurations, technologies, etc. may result in implementations that remain consistent with the teachings presented herein.
System 100 may comprise a frame 102 on which at least one sensor 104 (e.g., hereafter, “sensor 104”) and device 106 may be mounted. “Mounting” may include sensor 104 and device 106 being attached to frame 102 via mechanical attachment (e.g., screw, nail or other fastener), adhesive attachment (e.g., a glue, epoxy, etc.) or being incorporated within the structure of frame 102. Frame 102 is disclosed as a pair of eyeglasses only for the sake of explanation. Eyeglasses make an appropriate foundation on which various features consistent with the present disclosure may be implemented. Moreover, since eyeglasses, sunglasses, safety glasses, etc. are already routinely worn by people, it also means that there is little barrier to adoption of the technology. Users are not required to wear or carry additional equipment dedicated only to voice capture. Notwithstanding the foregoing advantages offered by eyeglasses of the types mentioned above, the teachings disclosed herein may alternatively be embodied in different form factors including, for example, any structure that touches, or is at least in proximity to, the nose and may be able to act as a platform for the variety of systems, devices, components, etc. that are described herein.
Sensor 104 may comprise vibration sensing circuitry. In at least one embodiment, the sensing circuitry may comprise, for example, piezoelectric components such as a diaphragm. Piezoelectric diaphragms may convert vibration (e.g., mechanical pressure waves) into electronic signals. Consistent with the present disclosure, the vibration sensing circuitry in sensor 104 may be in contact with, or at least proximate to, the nose of a user wearing frame 102. For example, the bridge of the user's nose is bone, and may resonate when the user speaks. Sensor 104 may be able to detect the vibration caused by the nasal bones resonating with the user's voice, and may convert the sensed vibration into an electronic signal that is then provided to device 106.
Device 106 may be configured to perform activities in system 100 such as, for example, generating voice data from the electronic signal generated by sensor 104, transmitting the voice data to external device 116, receiving audio data from external device 116, generating sound based on the received audio data, identifying and processing local commands, etc. Device 106 may comprise, for example, control circuitry 108, communication circuitry 110, user interface 112 and power circuitry 114. Control circuitry 108 may comprise at least data processing and memory resources. Data processing resources may include, for example, one or more processors situated in separate components, or alternatively one or more processing cores embodied in a component (e.g., in a System-on-a-Chip (SoC) configuration), and any processor-related support circuitry (e.g., bridging interfaces, etc.). Example processors may include, but are not limited to, various x86-based microprocessors available from the Intel Corporation including those in the Pentium®, Xeon®, Itanium®, Celeron®, Atom®, Quark®, Core i-series, product families, Advanced RISC (e.g., Reduced Instruction Set Computing) Machine or “ARM” processors, etc. Examples of support circuitry may include chipsets (e.g., Northbridge, Southbridge, etc. available from the Intel Corporation) to provide an interface through which the data processing resources may interact with other system components that may be operating at different speeds, on different buses, etc. in device 106. Some or all of the functionality commonly associated with the support circuitry may also be included in the same physical package as the processor (e.g., such as in the Sandy Bridge family of processors available from the Intel Corporation).
The data processing resources may be configured to execute various instructions in device 106. Instructions may include program code configured to cause the data processing resources to perform activities related to reading data, writing data, processing data, formulating data, converting data, transforming data, etc. Information (e.g., instructions, data, etc.) may be stored in the memory resources. The memory resources may comprise random access memory (RAM) or read-only memory (ROM) in a fixed or removable format. RAM may include volatile memory configured to hold information during the operation of device 106 such as, for example, static RAM (SRAM) or Dynamic RAM (DRAM). ROM may include non-volatile (NV) memory circuitry configured based on BIOS, UEFI, etc. to provide instructions when device 106 is activated, programmable memories such as electronic programmable ROMs (EPROMS), Flash, etc. Other fixed/removable memory may include, but are not limited to, magnetic memories such as, for example, floppy disks, hard drives, etc., electronic memories such as solid state flash memory (e.g., embedded multimedia card (eMMC), etc.), removable memory cards or sticks (e.g., micro storage device (uSD), USB, etc.), optical memories such as compact disc-based ROM (CD-ROM), Digital Video Disks (DVD), Blu-Ray Disks, etc.
Communication circuitry 110 may manage communications-related operations for device 106, which may include resources configured to support wired and/or wireless communications. Device 106 may comprise multiple sets of communication circuitry 110 (e.g., including separate physical interface circuitry for wired protocols and/or wireless radios). Wired communications may include serial and parallel wired mediums such as, for example, Ethernet, Universal Serial Bus (USB), Firewire, Thunderbolt, Digital Video Interface (DVI), High-Definition Multimedia Interface (HDMI), etc. Wireless communications may include, for example, close-proximity wireless mediums (e.g., radio frequency (RF) such as based on the RF Identification (RFID) or Near Field Communications (NFC) standards, infrared (IR), etc.), short-range wireless mediums (e.g., Bluetooth, WLAN, Wi-Fi, etc.), long range wireless mediums (e.g., cellular wide-area radio communications, satellite-based communications, etc.), electronic communications via sound waves, etc. In one embodiment, communication circuitry 110 may be configured to prevent wireless communications from interfering with each other. In performing this function, communication circuitry 110 may schedule communication activities based on, for example, the relative priority of messages awaiting transmission.
User interface circuitry 112 may include hardware and/or software to allow users to interact with device 106 such as, for example, various input mechanisms (e.g., microphones, switches, buttons, knobs, keyboards, speakers, touch-sensitive surfaces, one or more sensors configured to capture images and/or sense proximity, distance, motion, gestures, orientation, biometric data, etc.) and various output mechanisms (e.g., speakers, displays, lighted/flashing indicators, electromechanical components for vibration, motion, etc.). The hardware in user interface circuitry 112 may be incorporated within device 106 and/or may be coupled to device 106 via a wired or wireless communication medium. Power circuitry 114 may include internal power sources (e.g., battery, fuel cell, etc.) and/or external power sources (e.g., power grid, electromechanical or solar generator, external fuel cell, etc.) and related circuitry configured to supply device 106 with the power needed to operate.
External device 116 may include equipment that is at least able to process the voice data generated by device 106. Examples of external device 116 may include, but are not limited to, a mobile communication device such as a cellular handset or a smartphone based on the Android® OS from the Google Corporation, iOS® or Mac OS® from the Apple Corporation, Windows® OS from the Microsoft Corporation, Linux® OS, Tizen® OS and/or other similar operating systems that may be deemed derivatives of Linux® OS from the Linux Foundation, Firefox® OS from the Mozilla Project, Blackberry® OS from the Blackberry Corporation, Palm® OS from the Hewlett-Packard Corporation, Symbian® OS from the Symbian Foundation, etc., a mobile computing device such as a tablet computer like an iPad® from the Apple Corporation, Surface® from the Microsoft Corporation, Galaxy Tab® from the Samsung Corporation, Kindle® from the Amazon Corporation, etc., an Ultrabook® including a low-power chipset from the Intel Corporation, a netbook, a notebook, a laptop, a palmtop, etc., a wearable device such as a wristwatch form factor computing device like the Galaxy Gear® from Samsung, Apple Watch® from the Apple Corporation, etc., a typically stationary computing device such as a desktop computer, a server, a group of computing devices organized in a high performance computing (HPC) architecture, a smart television or other type of “smart” device, small form factor computing solutions (e.g., for space-limited applications, TV set-top boxes, etc.) like the Next Unit of Computing (NUC) platform from the Intel Corporation, etc. or combinations thereof.
In an example of operation, system 100 may be worn by a user and activated manually by user interaction with user interface circuitry 112, or automatically by the user activating external device 116, activating an application on external device 116, speaking a local command, etc. In speaking a local command, device 106 may be in a power conservation mode and the speaking of a certain sound, word, phrase, etc. may be recognized by device 106 (e.g., in electronic signal form or after converted to voice data) as a local command to activate system 100 (e.g., transition device 106 from the power conservation mode to an active mode). Other local commands may, for example, deactivate system 100, mute system 100 (e.g., temporarily stop sensing operations or transmission operations), increase or decrease speaker volume, etc. Following the activation of system 100, sensor 104 may sense vibration in the nose of the user (e.g., the bony bridge of the user's nose), and may generate an electronic signal based on the vibration. The electronic signal may be received by device 106, which may generate voice data based on the electronic signal. For example, control circuitry 108 may convert the analog electronic signal into digital voice data. The next operation depends on the situation in which system 100 is being utilized. For example, if simple dictation is occurring then control circuitry 108 may store the voice data in memory for later retrieval. If engaged in a telephone call then communication circuitry 110 may transmit the voice data to external device 116 (e.g., a mobile communication device) and may receive audio data from external device 116 pertaining to the other party in the call. User interface circuitry 112 may then generate sound via, for example, speaker 118 so that the user may interact with the other caller. In at least one embodiment, the sound of the user's own voice may be generated through speaker 118 to provide auditory feedback to the user of system 100.
FIG. 2 illustrates an example configuration for sensor 104′ in accordance with at least one embodiment of the present disclosure. FIG. 2 shows sensor 104′ within a nosepiece 200. Nosepiece 200 may comprise, for example, at least sensing circuitry 202 affixed to structural support 204. Sensing circuitry 202 may include, for example, a piezoelectric diaphragm to convert vibration 206 into an electronic signal. Vibration 206 may occur due to cranial bones resonating from a user talking. This effect has dual benefits in that it allows the user's voice to be captured while also screening out external noise based on the human skulls natural ability to dampen external noise. The use of piezoelectric diaphragms is beneficial in that they are able to accurately generate an electronic signal indicative of voice and do not require external power (e.g., the pressure waves may compress a piezoelectric crystal to generate the electronic signal).
While wire 208 is shown in FIG. 2 to convey the electronic signal to device 106, the use of wireless communication is also possible to transmit the electronic signal. A variety of sensor configurations may be implemented consistent with the present disclosure. For example, given that two nosepieces 200 exist in a common pair of glasses, at least one of the two nosepieces 200 may include sensor 104′. In another example implementation, both nosepieces 200 may include sensor 104′. The sensors 104′ in each nosepiece 200 may be wired in series to generate stronger electronic signals. In another embodiment, the sensors 104′ in each nosepiece 200 may be wired individually, and resources in device 106 (e.g., control circuitry 108) may then select the sensor 104′ to employ based on the strength of the electronic signals received from each sensor 104′. In this manner, system 100 may be able to account for the particularities in each user's nasal bones (e.g., breaks, natural deformities such as a deviated septum, etc.) and select the particular sensor 104′ that may provide the strongest and cleanest electronic signal to use in generating voice data.
FIG. 3 illustrates example operations for voice capture via nasal vibration sensing in accordance with at least one embodiment of the present disclosure. Operations in FIG. 3 shown with a dotted outline may be optional based on the particulars of an implementation including, for example, the capabilities of the system (e.g., of the sensors, devices, etc. within the system), the configuration of the system, the use for which the system is intended, etc. In operation 300, nasal vibration sensing may be activated. Activation may be manual (e.g. instigated by a user of the system) or automatic (e.g., triggered by external device activity, local commands, etc.). A determination may be made in operation 302 as to whether nasal vibration is sensed by at least one sensor in the system. If in operation 302 it is determined that nasal vibration is not sensed, then in operation 304 at least one corrective action may occur. Examples of correction action may include generating an audible, visible and/or tactile notification to the user, reinitiating the system as illustrated by the arrow leading back to operation 300, the selection of another sensor in the system (e.g., when the system is eyeglasses, of a sensor in the opposite nosepiece), etc.
If in operation 302 it is determined that nasal vibration is sensed, then in operation 306 voice data may be generated based on an electronic signal generated by the at least one sensor. A determination may be made in operation 308 as to whether the electronic signal and/or voice data included a local command. For example, a set of local commands may be configured in the system, and control circuitry in the system may compare the electronic signal and/or voice data to the set of local commands to determine if a match exists. If in operation 308 it is determined that a local command was received, then in operation 310 at least one activity may be executed based on the sensed local command. Examples of activities that may be performed include, but are not limited to, turning on/off the system, adjusting system volumes, temporarily disabling voice capture and/or voice data transmission, etc. A determination in operation 308 that a local command was not received may be followed by transmitting the voice data to the external device (e.g., a mobile communication device like smartphone) in operation 312. In operation 314, audio data (e.g., voice data corresponding to other participants in a telephone call) may be received from the external device. Sound may be generated based on the received audio data in operation 316, which may be followed by a return to operation 302 to continue nasal vibration sensing.
Sound Capture and Generation Via Nasal Vibration
Consistent with the present disclosure, device 106 may also cause sensor 104 to operate “in reverse” to communicate sound to a user by inducing vibration in the nose (e.g., nasal bone) of the user. Vibration induced in the nasal bone is conveyed through the skull to sound sensing organs in the inner ear (e.g., the cochlea), which interpret the induced vibration as sound. This operation may occur even if the user has some defect, injury, etc. that ordinarily would prevent the user from hearing sound (e.g., a ruptured eardrum). In general, device 106 may have audio data, or may receive audio data, that is used to cause sensor 104 to induce audio vibration in the nose of the user. The communication may be one-way (e.g., wherein the user only listens to the incoming sound) or two-way (e.g., wherein the user both listens to incoming sound and sound is also captured from the user). Different modes for facilitating two-way communication will be discussed herein including, but not limited to, one-channel mode and signal modulation mode.
In at least one embodiment, a system to capture and generate sound may comprise, for example, at least a frame wearable by a user, sensing circuitry mounted to the frame and a device also mounted to the frame. The sensing circuitry may be to sense voice vibration induced in the user's nose by the user's voice, generate an electronic signal based on the sensed voice vibration and induce audio vibration in the nose based on audio data. The device may be to at least control the operation of the sensing circuitry.
In at least one embodiment, the frame may be an eyeglass frame comprising at least one nosepiece to contact the nose, the at least one nosepiece including at least the sensing circuitry. The sensing circuitry may comprise at least one piezoelectric diaphragm to generate the electronic signal and induce the audio vibration. In at least one example implementation, the sensing circuitry may comprise a first sensing circuit to sense the voice vibration and a second sensing circuit to induce the audio vibration.
In at least one embodiment, an example device may comprise at least control circuitry to determine whether the system is initiating or engaged in two-way communication. If the control circuitry determines that the system is not initiating or engaged in two-way communication, the control circuitry may then generate voice data based on the electronic signal or cause the sensing circuitry to induce the audio vibration based on the audio data. If it is determined that the system is initiating or engaged in two-way communication, the control circuitry may operate in single channel mode or signal modulation mode. In single channel mode the control circuitry may cause the sensing circuitry to generate an indication at least when audio data is incoming, cause the sensing circuitry to induce the audio vibration based on the audio data and, when no audio data is incoming, generate the voice data based on the electronic signal. In signal modulation mode the control circuitry may modulate the audio data, cause the sensing circuitry to induce the audio vibration based on the modulated data, receive the electronic signal, filter out the audio vibration from the electronic signal and generate the voice data based on the electronic signal. The device may further comprise at least communication circuitry to at least one of transmit the voice data to an external device or receive the audio data from the external device. Consistent with the present disclosure, an example method for capturing and generating sound may comprise activating a system wearable by a user, determining whether the system is initiating or engaged in two-way communication, controlling, based on the determination, sensing circuitry in the system to at least one of sense voice vibration induced in the user's nose by the user's voice and generate an electronic signal based on the voice vibration, or induce audio vibration in the nose based on audio data.
FIG. 4 illustrates an example configuration for a sensor further operating as a transducer in accordance with at least one embodiment of the present disclosure. In the various embodiments illustrated in FIGS. 1 to 3, sensor 104′ was only relied upon to capture sound (e.g., voice) generated locally by a user. FIG. 4 shows an embodiment wherein sensor 104′ may operate as a transducer (e.g., both to capture local sound and also induce audio vibration in a user's nose) so that the user may hear sound based on audio data. Audio data may include any data stored in, or received by, device 106 for use in causing sensor 104′ to generate audio vibration. Audio data is described in the above examples a being a voice of another party in a telephone call in which the user of system 100 is participating. However, this is merely one example of audio data. Consistent with the present disclosure, system 100 may support one-way or two-way communications. One-way communications may comprise a user of system 100 either capturing voice data (e.g., recording for dictation, recording reminders, etc.) or listening to sound induced by nasal vibration. A user may only listen to sound when, for example, they are listening to music, spoken content such as recorded messages, an audio book, a lecture or other similar presentation. Audio data may be stored in device 106 (e.g., in memory within control circuitry 108) or may be received in device 106 (e.g., via communication circuitry 110). In an example of operation, a user may interact with user interface circuitry 112 in device 106 and/or external device 116 (e.g., with an audio application in external device 116) to select audio data and trigger the playback of audio data. Regardless of whether the audio data is stored within device 106 or streamed from an external source (e.g., from external device 116), control circuitry 108 may process the audio data, if required (e.g., to adjust the volume, frequency, pitch, tone, etc. of the audio data based on, for example, the manner in which sensor 104′ induces the audio vibration), and generate a signal (e.g., driving signal) that causes sensor 104′ to induce the audio vibration in the nose of the user. Two-way communications may involve both capturing sound locally generated by the user and also inducing audio vibration based on audio data. The most typical example of two-way communication is the user of system 100 talking on the phone.
FIG. 4 illustrates that, in addition to capturing vibration 206 generated by the user's voice (hereafter, “voice vibration 206”), sensor 104′ may further be able to induce audio vibration 400 (e.g., based on audio data). Examples of audio vibration are shown at 400A and 400B in FIG. 4. In at least one implementation, a single sensing circuit 202 may both sense voice vibration 206′ and induce audio vibration 400A. This may occur in that the actual sensor (e.g., a piezoelectric diaphragm) may continuously sense voice vibration 206′ in a substantially passive manner until provided with a signal from device 106 that causes to the piezoelectric diaphragm to actuate and induce audio vibration 400A. Thus, transitioning from passively sensing voice vibration 206′ to actively inducing audio vibration 400A may principally be controlled by device 106, which may selectively receive electronic signals generated by passive sensing or generate driving signals to induce audio vibration 400A. In a different implementation, sensor 104′ may include more than one sensing circuit 202. For example, multiple piezoelectric diaphragms may be incorporated in, or may at least be coupled to, one or both nosepieces 200 (e.g., depending on nosepiece and/or diaphragm size, shape, etc.). The plurality of piezoelectric diaphragms may be coupled in series to generate stronger electronic signals when sensing voice vibration 206′ and/or induce stronger audio vibration 400. In at least one embodiment, nosepieces 200 may each include piezoelectric diaphragms to generate audio vibrations 400A and 400B, respectively. Audio vibrations 400A and 400B may be induced to have amplitude or phase differences so that the source for each of the induced audio vibrations may be determined. The source indication may be utilized for, for example, calibration, debugging, etc. In another possible implementation, each of the plurality of piezoelectric diaphragms may be dedicated to only sensing voice vibration 206′ or inducing audio vibration 400. For example, sensing circuitry 202 may be dedicated to only sensing voice vibration 206′, while sensing circuitry 402 in the other nosepiece 200 may be dedicated to only inducing audio vibration 400B. In this instance, second coupling 404 (e.g., an additional wire) may be used to couple sensing circuitry 402 in the other nosepiece 200 to device 106. While illustrated as wire, coupling 404 may also be wireless connection (e.g., via Bluetooth, NFC, etc.).
Regardless of the actual configuration, at least one challenge posed by two-way operation is managing operation of sensor 104′. Voice vibration 206′ caused by the user's voice and audio vibration 400 induced based on incoming audio data could foreseeably occur concurrently, and thus, could interfere with each other. For example, a single piezoelectric diaphragm cannot both sense and generate vibration at the same time. As a result, voice vibration 206′ would be missed when audio vibration 400A is induced. Moreover, in a configuration where sensor 104′ includes a plurality of piezoelectric diaphragms dedicated only to sensing vibration or inducing vibration, a sensing piezoelectric diaphragm may sense both voice vibration 206′ and audio vibration 400B when they occur concurrently. Voice data generated using this captured mix of voice vibration 206′ and audio vibration 400B may be may be garbled, unintelligible, etc., and thus, unusable.
Consistent with the present disclosure, control circuitry 108 in device 106 may facilitate two-way communication by operating in a mode that avoids the above situations. While various operational modes are disclosed herein, these operational modes are offered merely as examples of ways to avoid the above issues, and are not intended to limit the disclosed embodiments to any particular manner of operation. A first example mode of operation is single channel operation. In single channel operation, control circuitry 108 may limit sensor 104′ to only to sensing voice vibration 206′ or generating audio vibration 400. An indication such as, for example, a short tone, a short vibration (e.g., from electromechanical circuitry in user interface circuitry 512, etc. may indicate to the user at least when audio data is incoming. The incoming audio indication may help prevent the user from attempting to talk over audio vibration 400, which would result in the voice of the user not being recorded. In at least one embodiment, another indication may inform the user that all of the incoming audio data has been presented (e.g., via audio vibration 400), allowing the user to proceed with voice capture.
In signal modulation mode, control circuitry 108 may modulate the audio data, or a signal generated from the audio data for driving sensor 104′ to induce audio vibration 400, so that noise including audio vibration 400 may later be filtered out from the capture of voice vibration 206′. Modulation, as referenced herein, generally comprises the modification of at least one property of a waveform. For example, the frequency of the signal driving sensor 104′ may be modified to make it higher or lower than the expected frequency of voice vibration 206′. As a result, while it may be possible to capture both voice vibration 206′ and audio vibration 400 that is occurring at the same time, low-pass or high-pass filtering may later be employed by control circuitry 108 to filter out captured the noise (e.g., audio waveform 400) from the desired waveform (e.g., voice vibration 206′). The waveform may be converted to voice data for storage, transmission, etc.
FIG. 5 illustrates example operations for sound capture and generation via nasal vibration in accordance with at least one embodiment of the present disclosure. The operations illustrated in FIG. 5 relate to different operational modes available in a system. Not all of the operations are required for all of the operational modes. Thus, while the entire operational flow shown in FIG. 5 allows a system to select a particular operational mode from the available operational modes, a subset of these operations may be used in systems that operate utilizing fewer operational modes.
In operation 500 the system may be activated. A determination may then be made in operation 502 as to whether the system is initiating or engaged in two-way communication. If in operation 502 it is determined that the system is not engaged in two way communication, then in operation 504 a further determination may be made as to whether to only capture the voice of the user. A determination in operation 504 that only user voice will be captured may be followed by operations 300 to 312 in FIG. 3 to capture the user's voice via nasal vibration sensing. Operation 312 may be followed by a return to operation 502. Returning to operation 504, a determination that user voice will not be captured may be followed operation 506 wherein incoming audio data may be received from an external device. The dotted outline of operation 506 indicates that the operation may only be performed if necessary (e.g., the audio data may already be present in the system if it is not being downloaded, streamed, etc. from an external device). In operation 508, audio vibration may be induced in the nose (e.g., nasal bone) of the user based on the audio data. Operation 508 may be followed by a return to operation 502.
Returning to operation 502, if a determination is made that the system is initiating or engaged in two-way communication, then in operation 510 a further determination may be made as to whether the system will utilize a single channel operational mode. If in operation 510 it is determined that the system will utilize a single channel operational mode, then in operation 512 a determination may be made as to whether there is incoming audio data (e.g., from another person participating in a phone call). A determination in operation 512 that there is no incoming audio data may be followed by operations 300 to 312 in FIG. 3 to capture the user's voice via nasal vibration sensing. Operation 312 may be followed by a return to operation 502. Returning to operation 512, if it is determined that audio data is incoming, then in operation 514 the system may indicate the incoming audio data to the user (e.g., with a tone, vibration, etc.). Audio data may then be received in operation 516, and in operation 518 audio vibration may be induced in the nose of the user based on the audio data. In optional operation 520 the end of the audio data may be indicated to the user (e.g., with a tone, vibration, etc.) so that the user may be informed that he/she may talk (e.g., that voice capture may resume). Operation 520 may be followed by operations 300 to 312 in FIG. 3 to capture the user's voice via nasal vibration sensing. Operation 312 may be followed by a return to operation 502.
Returning to operation 510, a determination that the system will not utilize the single channel operational mode may be followed by operation 522 wherein a further determination may be made as to whether the system will utilize signal modulation mode. If it is determined in operation 524 that the system will utilize signal modulation mode, then in operation 524 a further determination may be made as to whether there is any incoming audio data. A determination in operation 524 that there is no incoming audio data may be followed by operations 300 to 312 in FIG. 3 to capture the user's voice via nasal vibration sensing. Operation 312 may be followed by a return to operation 502. If in operation 534 it is determined that there is incoming audio data, then in operation 526 the incoming audio data may be received and modulated, or alternatively the signal used to drive sensing circuitry in the system to generate the audio vibration may be modulated. In operation 528 audio vibrations may be induced in the nose of the user using the modulated audio data. Given that the system comprises separate sets of sensing circuitry (e.g., piezoelectric diaphragms) to induce audio vibration and sense voice vibration, respectively, then the user of the system speaking during the generation of the audio vibration may result in both the user's voice and the audio vibration being captured. The electronic signal generated by the sensing circuitry that senses voice vibration may then include combined voice and audio data. The electronic signal that possibly includes both voice and audio data may then be received in operation 530. In operation 532 the modulated audio data may be filtered out from the electronic signal (e.g., by control circuitry in the system) to yield an electronic signal that only includes the voice data. Operation 532 may be followed by operations 306 to 312 in FIG. 3 to process the remaining voice data extracted from the mixed voice and audio vibration signal in operation 532. Operation 312 may be followed by a return to operation 502. Returning to operation 522, if it is determined that signal modulation mode will not be utilized then the communication operations may be complete. Operation 522 may be followed by a return to operation 500 to await the next activation of the system.
