Abstract
A speech recognition apparatus and method for use in a car navigation system performs speech processing for recognizing speech or spoken words referring to a specified region. An input audio signal or vocalized speech undergoes speech processing to determine and recognize the region specified in the speech. Data corresponding to the specified region is converted to coordinate position data for the region, and a map of the vicinity of the converted coordinate position data is displayed. When a new audio signal is input during speech recognition processing of a previously-input audio signal, the processing of the previously-input audio signal is interrupted and the new audio signal undergoes speech recognition processing. Accordingly, a high-efficiency operation of the car navigation system may be performed without interfering with the driving of the car. The speech recognition and apparatus also determines whether an input audio signal has been re-input within a predetermined amount of time from when the audio signal was previously input.
