    while the computing device receives the audio that includes the utterance and while the energy level of the audio that includes the utterance remains above the threshold energy level, obtaining, by the computing device, a transcription of the utterance spoken by the user; and

    while the computing device receives the audio that includes the utterance, while the energy level of the audio that includes the utterance remains above the threshold energy level, and based on the transcription of the utterance, overriding, by the computing device, the determination to delay designating an endpoint of the utterance spoken by the user and designating an endpoint of the utterance spoken by the user.
