Abstract
A method of automatically delineating turns in a multi-turn dialogue between a user and a conversational computing interface. Audio data encoding speech of the user in the multi-turn dialogue is received. The audio data is analyzed to recognize, in the speech of the user, an utterance followed by a silence. The utterance is recognized as a last utterance in a turn of the multi-turn dialogue responsive to the silence exceeding a context-dependent duration dynamically updated based on a conversation history of the multi-turn dialogue and features of the received audio, wherein the conversation history includes one or more previous turns of the multi-turn dialogue taken by the user and one or more previous turns of the multi-turn dialogue taken by the conversational computing interface.
