US Patent 10515623 Non-speech input to speech processing system

A system and method for a wearable device capable of detecting a wake gesture for purposes of capturing and forwarding audio data corresponding to a spoken utterance. The device may wake for purposes of capturing utterance audio data in response to a combination of a wake gesture and wakeword. The wake gesture may enable a wakeword detector. The device may also attempt to detect a wakeword utterance in a noisy environment. In response to determining the noisy environment, the device may receive motion data from a motion sensor; determining the motion data corresponds to a wake gesture, and send the audio data corresponding to an utterance to a remote device for processing. The device may also wake based on a combined confidence of wakeword and wake gesture detection.
