Abstract
Techniques for altering audio being output by an audio-controlled device, or another device, to enable more accurate automatic speech recognition (ASR) by the audio-controlled device. For instance, an audio-controlled device may output audio within an environment using a speaker of the device. While outputting the audio, a microphone of the device may capture sound within the environment and may generate an audio signal based on the captured sound. The device may then analyze the audio signal to identify a predefined non-speech command issued by a user within the environment. In response to identifying the predefined non-speech command, the device may somehow alter the output of the audio for the purpose of reducing the amount of noise within subsequently captured sound.
