Abstract: Aspects of the subject technology relate to a device including a microphone and a processor. The processor receives an audio signal corresponding to the microphone. The processor detects one or more of an ambient sound or a voice of a user of the device in the received audio signal. The processor applies a first gain to the ambient sound when the ambient sound is detected in the received audio signal and apply a second gain different than the first gain to the voice of the user of the device when the voice of the user of the device is detected in the received audio signal.

Abstract: Aspects of the subject technology provide for, while attenuating noise from a physical environment at a first device, for example, by active noise cancellation, outputting, by the first device, an audio signal for detection by a user. Aspects of the subject technology also provide, by the first device and to a second device, an indication of an estimated noise level of the attenuated noise at the first device for storage in association with an indication of whether the audio signal was detected by the user.

Abstract: Aspects of the subject technology provide for automatic adaptive noise cancellation, which may be provided with a substantially flat frequency response. In one or more implementations, a noise cancellation signal is combined with a pass-through audio signal with a ratio that is controlled based on a mixing curve. The mixing curve may be one of multiple mixing curves that are defined for multiple respective operational states of an electronic device.
