Chapter 2 - Phonetic and Phonological Background for Sibilant Analysis

Summary

Chapter 2 explains the phonetic and phonological background of sibilant analysis.It first establishes a definition of the phoneme and then continues to describe the sounds involved based on an articulatory point of view. These are then connected to acoustic theories of speech production that illustrate how prototypical articulatory gestures create the resulting sound waves that are perceived as phonemes. It specifically explains how source filter theory and turbulence are important to the production of sibilants. It then illustrates how the acoustic output created can be quantified and classified based on characteristics such as spectral mean, skewness, and kurtosis of the speech signal.

The chapter then moves on to suprasegmental theories and fundamentals of /str/-retraction research. It explains how exemplar models of the mental lexicon are suitable to describe the sound change at hand. It then briefly illustrates the uniqueness of triple-consonant clusters in English. As important processes in this sound change, coarticulation and assimilation are then differentiated.
