Abstract: Methods and systems are provided for controlling bone conduction, in which a bone conduction element may be used to output acoustic signals when it is in contact with a user. A bone conduction sensor may also be made in contact with the user, and used to obtain feedback relating to the outputting of the acoustic signals via the bone conduction element. The outputting of the acoustic signals may then be adaptively controlled based on processing of the feedback. The adaptive controlling may comprise adjusting components and/or functions related to or used in the outputting of the acoustic signals. For example, the adaptive controlling may comprise adjusting gain, frequency response, and/or equalization associated with a drive amplifier driving the bone conduction element.

Abstract: Methods and systems are provided for enhanced stereo audio recordings in electronic devices. Stereophonic recording performance in an electronic device, using a first microphone and a second microphone in the electronic device, may be assessed; and processing of signals generated by the first microphone and the second microphone may be configured based on the assessed stereophonic recording performance. The configuring may comprises adaptively modifying the processing to enhance stereophonic recording performance, to match or approximate an ideal performance. The assessing of the stereophonic recording in the electronic device may be based on a type of each of the first microphone and the second microphone, and/or based on a spacing therebetween. The processing may be adaptively modified to simulate directional reception of signals by the first microphone and the second microphone when the microphones are omnidirectional.

Abstract: Methods and systems are provided for adaptively managing a plurality of microphones and speakers in an electronic device. A mode of operation of the electronic device may be determined, and operation of at least one speaker may be managed, based on the determined mode of operation. The managing may comprise adaptively switching or modifying functions of the at least one speaker. For example, the at least one speaker may be configured to act as microphone or as vibration detector. Input obtained using the at least one speaker may be utilized in optimizing audio related functions, such as noise reduction and/or acoustic echo canceling.

Abstract: Methods and systems are provided for use of microphones with VSensors for wearable devices. VSensors may be used to detect and/or capture vibrations in bones. The captured bone vibrations may then be used to improve audio related operations. For example, bone vibrations may correspond to user audio input (e.g., speech), and as such the captured bone vibrations may be used in enhancing noise reduction functions in the wearable devices, by enabling distinguishing user audio input, as captured by microphone(s), from ambient noise. This may obviate the need to move the wearable device closer to the user's mouth (such that embedded microphones would be closer). The captured bone vibrations may also be analyzed to determine if they correspond to user control input (e.g., by means of finger tapping), such as by comparing them against predefined patterns.

Abstract: In a mobile device, a bone conduction or vibration sensor is used to detect the user's speech and the resulting output is used as the source for a low power Voice Trigger (VT) circuit that can activate the Automatic Speech Recognition (ASR) of the host device. This invention is applicable to mobile devices such as wearable computers with head mounted displays, mobile phones and wireless headsets and headphones which use speech recognition for the entering of input commands and control. The speech sensor can be a bone conduction microphone used to detect sound vibrations in the skull, or a vibration sensor, used to detect sound pressure vibrations from the user's speech. This VT circuit can be independent of any audio components of the host device and can therefore be designed to consume ultra-low power. Hence, this VT circuit can be active when the host device is in a sleeping state and can be used to wake the host device on detection of speech from the user.
