SPEECH RECOGNITION APPARATUS AND METHOD

If an adaptation is made taking into consideration the noise produced in a specific operating mode of a device in a case where the noise environment changes, a decline in recognition rate is expected during operation of the device in a mode for which no adaptation is made. Accordingly, the present operating mode of the device is detected, the name of data for speech recognition corresponding to the operating mode of the device is retrieved from a table that describes data for speech recognition, the retrieved data for speech recognition corresponding to the operating mode of the device is set and speech recognition processing is executed based upon the set data.
