AN AUTOMATIC SPEECH FORMANT TRACKING FILTER,

Abstract

As a solution to formant frequency measurement in real time, a continuously tuned, automatic tracking filter system is proposed which locates these spectral maxima of speech signals through an application of automatic frequency control techniques. The experimental circuitry is described, stability and performance characteristics are given for this feedback control system and several figures are shown to demonstrate the ability of the system to track speech formants. The problem of constructing a complete speech analysis system utilizing tracking filters is discussed. (Author)
