GRAMMAR ADAPTATION THROUGH COOPERATIVE CLIENT AND SERVER BASED SPEECH RECOGNITION

摘要

A system (200) and method (300) for grammar adaptation is provided. The method can include attempting a first recognition of a spoken utterance (304) using a first speech grammar (204), consulting (308) a second speech grammar (224) based on a recognition failure, and receiving a correct recognition result (310) and a portion of a speech grammar for updating (312) the first speech grammar. The first speech grammar can be incrementally updated, or expanded, to broaden grammar coverage for adapting to a user's vocabulary and grammar over time.
