Abstract

The development and preliminary testing of a system for tracking the first three formant frequencies of voiced speech is described. The technique involves both a frequency-domain analysis and a time-domain analysis. As speech is input to the system, a rough frequency-domain analysis is performed with a bank of fixed bandpass filters. Following this spectral analysis, an accurate time-domain analysis is performed utilizing a measure of the axis-crossing intervals of the filtered speech. In addition to the axis-crossing interval measure, the amplitude of the filtered speech signal is used in the analysis.
