The relation between fundamental frequencies and the resonant frequencies of the vocal tract

Abstract

The study was concerned with the frequency response of the vocal tract. This was undertaken On assumption that the vocal tract is an acoustical system having a series of coupled resonance elements with resonance peaks in the response frequencies. These resonance peaks are given by formants, and these formants were compared, in turn with the natural frequency of the vocal tract (Maximum increase in the intensity when the vocal tract was stimulated with an external source) as found by Nataraja (1972).
