Abstract: Implementations of the subject technology provide systems and methods for providing distributed audio processing for audio devices. Distributed audio processing may include encoding signals from multiple microphones and/or sensors, such as at a headphone or an earbud, and decoding and processing the signals on host, source, or companion device. Distributed audio processing may also include deactivating one or more digital signal processors and/or neural networks based on an operational mode of an audio device or based on a processing capability of a companion device.

Abstract: A device implementing an automatic speech recognition triggering system includes at least one processor configured to receive first and second audio signals respectively corresponding to first and second microphones of a device. The at least one processor is further configured to generate, based on at least one of the first or second audio signals, a third audio signal corresponding to a voice beam directed to an expected position of a mouth of a user. The at least one processor is further configured to determine whether wind noise is present in at least one of the first, second, or third audio signals. The at least one processor is further configured to, based on determining whether wind noise is present, an audio signal from among the second or third audio signals, for a determination of whether at least one of the first or second audio signals corresponds to the user.

Abstract: A signal processing method to determine whether or not a detected key-phrase is spoken by a wearer of a headphone. The method receives an accelerometer signal from an accelerometer in a headphone and receives a microphone signal from at least one microphone in the headphone. The method detects a key-phrase using the microphone signal and generates a voice activity detection (VAD) signal based on the accelerometer signal. The method determines whether the VAD signal indicates that the detected key-phrase is spoken by a wearer of the headphone. Responsive to determining that the VAD signal indicates that the detected key-phrase is spoken by the wearer of the headphone, triggering a virtual personal assistant (VPA).

Abstract: An earphone has a housing and a corresponding user-contact surface configured to urge against a user's anatomy. The housing defines an acoustic chamber and an acoustic port opening from the acoustic chamber. The user-contact surface is complementarily configured relative to the user's anatomy. When the earphone is donned, the user-contact surface forms an acoustic seal between the user-contact surface and the user's anatomy, acoustically coupling the acoustic chamber with the user's ear canal. An acoustic driver is positioned in the housing and acoustically coupled with the acoustic chamber. A microphone transducer acoustically couples with the acoustic port. A processing component is configured to detect a presence or an absence of anti-resonance in a spectral envelope observed by the microphone transducer.
