Abstract
A set of three custom-designed LSI circuits implements harmonic-sieve pitch extraction as can be used in vocoders. The set consists of a segmentation buffer for 256 speech samples, a discrete Fourier transform processor and a 16-bit micro-computer. In the application of a DFT vocoder, a pitch value can be extracted every 10 ms.
