PROBLEM TO BE SOLVED: To provide a speaking speed converting device which changes the speed of speech, without changing the properties of the pitch, timbre, etc., other than the speed of signal, including the speech in particular, and without causing the tone quality to deteriorate. SOLUTION: The speaking speed converting device has a speech-classifying means 41 of inputting speech waveform data and a speech code, based on linear prediction and classifying the input signal by the properties, and a speed adjusting means 42 of selecting either or both of speech conversion processing by using the speech waveform and speech conversion processing that uses the speech code, based upon classification and changing the speaking speed of the input signal by the selected methods.
