Abstract :
An algorithm is proposed for extracting the pitch of voiced speech. The method is based on approximating a given segment of the speech waveform in a least-squares sense by a finite Fourier series. In the approximation the fundamental frequency of the Fourier series, as well as its coefficients, is considered variable.
