Claim:
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 comparing the speech dialog to the conversation context model, to yield a context similarity score; modifying the context similarity score based on a head orientation of the speaker, to yield a modified context similarity score; when the modified context similarity score is above a threshold, incorporating a current user utterance into the conversation context model for use in the speech dialog; and when the modified context similarity score is one of equaling the threshold and 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.
