A VEHICLE SPEECH INTERACTIVE SYSTEM

摘要

A vehicle speech interactive system includes a speech acquiring module, a speech identification core module and a speech feedback module. The speech identification core module includes an acoustical model, a pronounce dictionary module, a context free grammar module and a path searching module. A mapping corresponding table is established corresponding to the change of the accent and the like by the acoustic model and the pronounce dictionary according to the statistical algorithm. The natural continuous speech to be identified and regular structure is structured by the context free grammar module. The observation probabilities calculate part with the maximal amount of calculation is approximately simplification.
