Speech production can be modeled mathematically to derive useful signal processing algorithms

Evidence

The acoustic production of speech signals can be approximated and modelled mathematically fairly easily (Fant, 1970). Based on such modelling, it is possible to derive signal processing algorithms that are found to be very useful in speech technology, like in speech synthesis and coding (Rabiner and Schafer, 1978). It also helps us to understand speech mechanisms. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 597
