5. The method of claim 1 , wherein suppressing the further output of the text-to-speech engine comprises at least temporarily ceasing an audio output of the text-to-speech engine.
1. A computer-implemented method comprising: receiving, by a computing device that includes (i) a text-to-speech engine, (ii) an automated speech recognizer, and (iii) a barge-in detection model that is trained to output an indication of whether given audio data comprises synthesized speech, an audio signal corresponding to a user's utterance that is spoken while the computing device is outputting synthesized speech; processing, using the barge-in detection model that is trained to output an indication of whether given audio data comprises synthesized speech, particular audio data that comprises data corresponding to the audio signal and data corresponding to the synthesized speech; in response to receiving an indication from the barge-in model that the particular audio data comprises synthesized speech, suppressing a further output of the text-to-speech engine; and outputting, by the automated speech recognizer, a transcription of the user's utterance without the synthesized speech.
