Abstract

See full text

A speech dialog system is described that adjusts a voice activity detection threshold during a speech dialog prompt to reflect a context-based probability of user barge in speech occurring. For example, the context-based probability may be based on the location of one or more transition relevance places in the speech dialog prompt.
