PROBLEM TO BE SOLVED: To provide a voice processor which transmits high quality voice, sets at transmission rate in accordance with required voice quality and has a flexible and wide utilization range. SOLUTION: A pitch synthesis filter 4 corrects pitch pulse signals which appear before and after peak pulse signals as the output signals of a multiplier 3. A phase synthesis filter 5 corrects the phase of the output signals of the filter 4. A minimum phase synthesis filter 6 corrects the phase so that the amplitudes of the output signals of the filter 5 become minimum and generates and transmits highly precise voice signals, thereby transmitting high quality voices.
