MULTI-DICTIONARY SPEECH RECOGNITION

摘要

A method and an in- vehicle system having a speech recognition component are provided for improving speech recognition performance. The speech recognition component may have multiple vocabulary dictionaries, each of which may include phonetics associated with commands. When the in-vehicle system receives speech input, the speech recognition component may determine whether the received speech input includes a speech access command. If the received speech input is determined to include a speech access command, then a dictionary changing component may transition a currently-used dictionary of the speech recognition component to a vocabulary dictionary associated with the determined speech access command. Otherwise, the dictionary changing component may transition the currently-used dictionary to a first vocabulary dictionary. A command included in the received speech input may then be recognized by the speech recognition component using the transitioned currently-used dictionary.
