Introduction

Abstract

Many different models have been postulated for quantitatively describing certain factors involved in the speech process. It can be stated with certainty that no single model has been developed which can account for all of the observed characteristics in human speech (nor would one probably desire such a model because of its inevitable complexity). A basic criterion of modeling is to find mathematical relations which can be used to represent a limited physical situation with a minimum of complexity and a maximum of accuracy. One of the most successful models of acoustical speech behavior is the linear speech production model developed by Fant [1960]. This model will be referred to throughout as the speech production model.
