Pitch detection is an essential technique in the various speech processing systems. The pitch period is useful for applications such as the speaker recognition, the speech synthesis and so on. A new frequency-time domain method in order to obtain a fundamental frequency of speech is presented in this paper. The paper also describes the results of the computer simulations and a real time pitch period detector using a conventional Digital Signal Processor. The algorithm uses the Discrete Running Fourier Series (DRFS) for emphasis of the peaks of the speech signal corresponding to the pitch and a new simple rule for the determination of the pitch period.
