Abstract:
A method for speaker adaptation of selected car commands in an in-vehicle speech command system for operating vehicle accessories by voice in moving and non-moving vehicles, comprising the steps of:(A) receiving from a speaker a spoken utterance having speaker-dependent speech characteristics corresponding to one of a set of known car commands for operating one of said vehicle accessories; (B) processing said spoken car command utterance according to a recognition parameter; (C) identifying an N-best set of known car commands matching said spoken car command utterance; (D) identifying whether said spoken car command utterance presents a training mode input by evaluating the state of said vehicle accessories during which said spoken car command utterance is spoken; (E) outputting said N-best command set to said speaker only if said training mode input is identified; (F) receiving speaker input selecting a correct car command from said N-best command set; and (G) adjusting said recognition parameter so that said speech command system adapts to said speaker by recognizing as said correct car command said spoken car command utterance having said speech characteristics.
