Abstract: This relates to providing an indication of the suitability of an acoustic environment for performing speech recognition. One process can include receiving an audio input and determining a speech recognition suitability based on the audio input. The speech recognition suitability can include a numerical, textual, graphical, or other representation of the suitability of an acoustic environment for performing speech recognition. The process can further include displaying a visual representation of the speech recognition suitability to indicate the likelihood that a spoken user input will be interpreted correctly. This allows a user to determine whether to proceed with the performance of a speech recognition process, or to move to a different location having a better acoustic environment before performing the speech recognition process.

Abstract: A device can be worn by a user and can include a microphone to analyze music and other sound in the surrounding environment. In one embodiment, the device can translate audio into a haptic and/or light of the sound's or music's bassline, in real-time. In one embodiment, no music is recorded by the device. The haptic or vibrational representation of the music can be generated by a motor. In some examples, the light representation of the music can be generated via a red/green/blue light emitting diode.

Abstract: Example embodiments relating to the adjustment of a microphone attached to a headset are provided. The adjustable headset detects a microphone attached to the headset at a first position and receives one or more speech signal inputs from a user. The headset calculates a feedback parameter which includes a confidence parameter, a vocabulary assistance parameter, and a node exit attempt parameter. The headset determines a pass state in an instance in which the feedback parameter satisfies a feedback threshold, to maintain the microphone at the first position. The headset determines a fail state in an instance in which the feedback parameter fails to satisfy a feedback threshold, to cause a stepper motor to move the microphone from the first position to a second position relative the user.

Abstract: Example techniques may involve performing aspects of a spectral calibration using an applied spatial calibration. An example implementation may include receiving data representing spatial filters that correspond to respective playback configurations. The implementation may also involve causing the audio drivers to output calibration audio that is divided into a repeating set of frames, the set of frames including a respective frame for each playback configuration. Causing the audio drivers to output the calibration audio may involve causing an audio stage to apply, during each frame, the spatial filter corresponding to the respective playback configuration. The implementation may also include receiving data representing spectral filters that correspond to respective playback configurations, the spectral filters based on the calibration audio output by the audio drivers.

Abstract: The present invention makes it possible to reduce noise from a driving unit with a two-channel microphone configuration. An audio processing apparatus has a first microphone whose main acquisition target is sound from outside of the apparatus, a second microphone whose main acquisition target is driving noise from the driving unit, and a noise removing unit that generates two-channel audio data in which driving noise made by the driving unit of the apparatus has been reduced based on the difference between time-series audio data acquired by the first microphone and time-series audio data acquired by the second microphone. This noise removing unit has two adaptive filter units that respectively perform filter processing on time-series audio data from the first microphone and time-series audio data from the second microphone, and generates stereo two-channel audio data.

Abstract: In one embodiment, a gain redistribution application restructures gains associated with multiple microphones included in a head-worn audio system to minimize near field noise. In response to a sound generated by a sound source, the microphones generate input signals. The gain redistribution application performs mixing operations on the input signals to generate an output signal that mitigates near field noise associated with the same side of the head as the sound source. Subsequently, the gain redistribution application transmits the output signal to a speaker that targets the same side of the head as the sound source. Advantageously, by reducing the gain associated with an input signal received via a microphone located on the same side of the head as the sound source, the gain redistribution application reduces near field noise transmitted to the user during operation in a more comprehensive fashion relative to conventional designs.
