An effectivemeth- od is in itiated in th ispaper, in wh ich pitch period of voice is extracted by themeans of displacementmatching in seg- emen.t Th is can effectively prevent from judging two smi ilarwaves in one period of cycle as wt o periods of cycle. It can also prevent the possib ility of getting the period-doubling at the same tmi e. A series of expermi ents have proved that the pitch period extracted by this method is accurate and the systhesized speech of a given people is satisfactory.
