PROBLEM TO BE SOLVED: To provide a speaking speed conversion apparatus and the like for obtaining synthesized voices which are easy to hear even if environment changes. SOLUTION: When supplied with data representing a fixed form message, a sound piece edition section 8 retrieves the sound piece data of the sound piece matching in reading with the sound pieces within the fixed form message from a sound piece database 10, determines an utterance speed and has the sound piece data converted by a speaking speed conversion section 11 so as to match the speed with the determined speed. The utterance speed is determined based on the speed of a moving body detected by a speed detecting section 12. On the other hand, the sound piece edition section 8 performs the rhythm prediction of the fixed form message and the like and specifies the data most appropriately matching with the respective sound pieces within the fixed form message from the retrieved sound piece data piece by piece. The data indicating the synthesized voices is formed by coupling the specified sound piece data or in turn the waveform data supplied to an acoustic processing section 4 because the specification is not possible to each other.
