ALTERING AUDIO TO IMPROVE AUTOMATIC SPEECH RECOGNITION
This abstract first appeared for US patent application 20250124920 titled 'ALTERING AUDIO TO IMPROVE AUTOMATIC SPEECH RECOGNITION
Original Abstract Submitted
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.
