Speech Production and Modellings in the vocal tract. The flow-waveform thus created is further modulated by the resonances of the vocal tract. These features form the characteristic properties of phones. For efficient coding, we must model these features with a minimum number of parameters without altering the perceptual impressi

Spectral Envelope and Perceptual Masking Modelsource model of the speech signal. Perceptual (frequency) masking models are evaluation models, which describe the magnitude of the perceptually detrimental effect of errors in different parts of the spectrum. The two models tend to have similar shapes, whereby they are described jointly in this chap

Residual Coding The residual from these two filters is a signal without almost any temporal correlation. In this section we describe modelling and optimisation of the residual quantisation. The most famous approach is algebraic coding, which has also given the name to algebraic code-excited linear prediction (ACEL
