1. A method, comprising:
obtaining an audio signal with a microphone of a device, the audio signal including a voice component and an ambient noise component;
generating, with a sidetone filter of the device based on the audio signal, a sidetone signal including the voice component and a residual portion of the ambient noise component, wherein the residual portion is a remaining portion of the ambient noise component that has been processed based at least in part on an accelerometer signal from an accelerometer; and
generating, with an active noise cancellation filter of the device, a noise cancellation signal configured to suppress the residual portion of the ambient noise component of the sidetone signal.
