Determination of vowel zones in speech
Abstract
An automatic, vowel determination method using a set of parameters which are functions of the frequency distribution of the signal energy is presented. The classification algorithm makes sequential decisions based on comparison with threshold values obtained experimentally. The voice signal filtered at 4.4 kHz is sampled at 10 kHz and quantized at 12 bits per sample. The experimental results assure 95% recognition of the vowel sounds.
