Abstract
A method of adjusting a predefined listening time of a voice assistant device includes receiving an audio input; extracting at least one of a speech component and a non-speech artifact from the audio input; determining a user breathing pattern based on the at least one of the speech component and the non-speech artifact; identifying at least one attribute that impact the user breathing pattern based on at least one non-speech component, captured from an environment and the voice assistant device; determining, after detecting a pause in the audio input, whether a user's intention is to continue a conversation based on an analysis of the user breathing pattern and the at least one attribute; and dynamically adjusting the predefined listening time of the voice assistant device to continue listening for voice commands in the conversation based on a determination that the user's intention is to continue the conversation.
