Abstract:
This paper presents a data-driven approach to the modelling of voice source waveforms. The voice source is a signal that is estimated by inverse-filtering speech signals with an estimate of the vocal tract fil-ter. It is used in speech analysis, synthesis, recognition and coding to decompose a speech signal into its source and vocal tract filter com-ponents. Existing approaches parameterize the voice source signal with physically- or mathematically-motivated models. Though the models are well-defined, estimation of their parameters is not well understood and few are capable of reproducing the large variety of voice source waveforms. Here we present a data-driven approach to classify types of voice source waveforms based upon their mel-frequency cepstrum coefficients with Gaussian mixture modelling. A set of ‘prototype ’ waveform classes is derived from a weighted average of voice source cycles from real data. An unknown speech signal is then decomposed into its prototype components and resyn-thesized. Results indicate that with sixteen voice source classes, low resynthesis errors can be achieved.
