# Phonetics and Signal Processing

• Sean A. Fulop
Chapter
Part of the Signals and Communication Technology book series (SCT)

## Abstract

The purpose of this chapter is twofold, so it is divided into two large sections. The first section provides a very quick overview of phonetics, not only for the benefit of scientists who have limited knowledge of the subject, but also to fix some concepts and notation for the rest of the book. The second section provides a quick introduction to the fundamentals of digital signal processing that will be relied upon to discuss the spectrum analysis techniques presented in later chapters. While the most complicated mathematical derivations and digressions have been set within gray boxes, and can thus be skimmed over by less mathematically inclined readers, this section does include a fair amount of mathematics in the main text. I found this to be necessary to accomplish my main goal, which is to present the fundamentals of signal processing to the uninitiated in a simplified format that will facilitate learning of those concepts which are essential to understanding the methods presented in later chapters. Readers whose background is too deficient in mathematics to permit understanding the equations will, I hope, still be able to learn many important concepts by focusing on the discussions, examples, and figures.

## Keywords

Discrete Fourier Transform Instantaneous Frequency Window Function Vocal Tract Real Signal
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
