Abstract

A method for managing interactive dialog between a machine and a user is claimed. In one embodiment, an interaction between the machine and the user is managed in response to a confidence value, wherein the confidence value is dependent upon speech recognition confidence and at least one non-acoustic confidence value. The non-acoustic confidence values can be turn-taking confidence, speech duration confidence, state-completion confidence or mode confidence. In multiple embodiments, the non-acoustic confidence value can be dependent upon a timing position of the possible speech onset. The non-acoustic confidence value can be dependent upon a duration of an audio input. The non-acoustic confidence value can be dependent upon a model of user attention. The non-acoustic confidence value can be dependent upon a history of exit conditions associated with interactions during a course of a session.
