Abstract
The voice prompt of an interactive system is adjusted based upon a state of a user. An utterance of the user is received, and the state of the user is determined based upon signal processing of the utterance of the user. Once the state of the user is determined, the voice prompt is adjusted by adjusting at least one of a tone of voice of the voice prompt, a content of the voice prompt, a prosody of the voice prompt, and a gender of the voice prompt based upon the determined state of the user.
