A voice synthesizing system can make necessary calculation amount satisfactorily small and can make necessary file size small. The system includes a compressed pitch segment database storing compressed voice waveform segments, a pitch developing portion reading out the voice waveform segment from the database and decompressing the compressed data for reproducing an original voice waveform segment when the voice waveform segment necessary for voice waveform synthesis is demanded, and a cache processing portion temporarily storing the voice waveform segment already used in voice waveform synthesis, and when voice waveform segment necessary for voice waveform synthesis is demanded, returning demanded voice waveform segment to a demander when demanded voice waveform segment is already stored, and obtaining the voice waveform segment from the database via the pitch developing portion to hold the obtained voice waveform segment and return to the demander when demanded voice waveform segment is not stored.
