Abstract: Aspects of the subject technology provide for generation of a self-voice signal by an electronic device that is operating in an active noise cancellation mode. In this way, during a phone call, a video conference, or while listening to audio content, a user of the electronic device may benefit from active cancellation of ambient noise while still being able to hear their own voice when they speak. In various implementations described herein, the concurrent self-voice and automatic noise cancellation features are facilitated by accelerometer-based control of sidetone and/or active noise cancellation operations.

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 relate to a device including a microphone, a filter and a processor. The filter receives an audio signal including ambient noise and a voice of a user of the device from the microphone. At least a portion of ambient noise is filtered from the audio signal. The processor determines a level of the ambient noise in the received audio signal and dynamically adjusts a gain applied to the filtered audio signal based on the level of the ambient noise.

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.
