ABSTRACT:
A memory and a counter are used to count and store the number of times the same block address extracted by a block detection section is read. A scan speed calculation section calculates a scan speed on the basis of the number of times the same block address is read. A reproduction speed determination section determines a speech reproduction speed from this scan speed. A sampling frequency changing section generates a sampling frequency corresponding to the determined reproduction speed. A D/A converter D/A-converts speech data decoded by a decoding section at the reproduction sampling frequency. The converted data is filtered by a low-pass filter corresponding to the reproduction sampling frequency. The resultant data is output to a loudspeaker.
