Usual pitch extractors are designed for the use of vocoder and have relatively large time constant. But it is thought necessary to convert pitch frequency into analog voltage with small time constant for the sake of the analysis or the recognition of speech. The pitch extractor having small time const. (10m sec. ) was designed and built, namely, pitch is detected from three formant envelopes, and the discriminator changes it into voltage after SSB modulation and amplitude clipping.
