Abstract
A speech recognition system for use in an automobile navigation system performs speech processing for recognizing speech or spoken words that correspond to a name of a place and a word designating a desired operation of the navigation system. When a new audio signal is input during speech recognition processing of a previously input audio signal, by holding a talk switch down for a fixed time period, the processing of the previously input audio signal is canceled, and the new audio signal immediately undergoes speech recognition processing without requiring any continuation of the processing of the previously input audio signal. The speech recognition system also determines whether an input audio signal has been reinputted within a predetermined amount of time from when the audio signal was previously inputted.
