Abstract:
1. A method comprising: generating a conversation context model based on user utterances and facial recognition data, wherein the conversation context model comprises a model of a speech dialog occurring between a speech dialog system and a speaker; continuously monitoring the speech dialog; receiving a current user utterance from the speaker, wherein the current user utterance is a natural language input not intended to trigger speech processing; comparing, via a processor, the current user utterance to the conversation context model to generate a context similarity score; modifying the context similarity score based on a head orientation of the speaker and the facial recognition data, to yield a modified context similarity score; when the modified context similarity score is above a threshold, incorporating the current user utterance into the conversation context model for use in the speech dialog; and when the modified context similarity score is below the threshold, suppressing the current user utterance such that the current user utterance is not incorporated into the conversation context model and the speech dialog produces speech as though the current user utterance is not in the conversation context model.
