Abstract

Processor for the detection of the pitch of a speech wave for use in connection with a vocoder system. It comprises means for detecting the major peaks of the speech wave, means for converting said major peaks into marker pulses defining therebetween pitch periods and a processor unit for treating the marker pulses. The program of treatment is the following: (i) omission of a marker pulse separated from the preceding marker pulse by an interval shorter than the preceding period by more than a tolerance amount with prohibition to omit two consecutive marker pulses; (ii) selection of the preceding period if the actual period is larger or shorter than the said preceding period by more than a tolerance amount with prohibition to select two times in succession the preceding period; (iii) division by two of the value of the pitch if it is larger than a lower limit, say 15ms or 8ms for respectively a male and a female voice.
