PROBLEM TO BE SOLVED: To provide a speech data selecting apparatus or the like for use in obtaining natural synthesized speech at high speed with simple configuration. SOLUTION: When data representing a routine message are supplied, a sound piece editing part 8 retrieves sound piece data of a sound piece where the sound piece in the routine message is matched with the reading from a sound piece database 10, and converts the sound piece data so as to be matched with the speed indicated by the utterance speed data. At the same time, the sound piece editing part 8 predicts rhythm of the routine message, and specifies one by one among retrieved sound piece data, which is best matched with each sound piece in the routine message, on the basis of an evaluation equation. The variables of the evaluation equation are the results of the first recursion in frequencies of pitch components and time difference of utterance speed between the rhythm prediction results and sound piece data. Then, the data representing a synthesized speech are generated by combining the specified sound piece data, and waveform data which is supplied by a sound processing unit 4 as a substitute due to failure to be specified.
