This paper describes a novel speech analysis application which was implemented using a Motorola M68HC11 microcontroller system. This microcontroller-based platform was designed to function as a pitch extractor for voiced speech in real time. In this context, pitch extraction is the identification of

A high-performance method for pitch extraction is proposed for the purposes of real-time sequential speech processing that can be used in such applications as speech rate conversion systems. According to this method, autocorrelation functions of the input speech waveforms are calculated for one anal
