Abstract:
Techniques for altering audio being output by a voice-controlled device, or another device, to enable more accurate automatic speech recognition (ASR) by the voice-controlled device. For instance, a voice-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 speech of a user within the signal, with the speech indicating that the user is going to provide a subsequent command to the device. Thereafter, the device may alter the output of the audio (e.g., attenuate the audio, pause the audio, switch from stereo to mono, etc.) to facilitate speech recognition of the user's subsequent command.

Claim (Index 1):
An apparatus comprising:\n one or more processors; and computer-readable media storing computer-executable instructions that, when executed on the one or more processors, cause the one or more processors to:\n cause a speaker to output first audio; \n receive an input audio signal generated by a microphone based at least in part on sound captured by the microphone; \n detect a predefined utterance within the input audio signal, the predefined utterance indicating that a voice command is going to be provided; \n alter, based at least in part on detecting the predefined utterance, output of the first audio by the speaker for a first period of time; \n send, to one or more remote computing resources and based at least in part on detecting the predefined utterance, the input audio signal for identifying the voice command in the input audio signal; and \n cause the speaker to at least one of:\n output the first audio for a second period of time that is after the first period of time; or \n output second audio for the second period of time, wherein the second audio is different than the first audio.
