The text sets out in simple and accessible terms the various methods of acoustic analysis of speech, placing them in their historical context, allowing a better understanding of the mathematical and technical solutions adopted today in phonetics and experimental phonology. Without mathematical complications, the operating bases of the many speech analysis software currently available are exposed so that everyone can understand the limits and avoid errors and misinterpretations in their implementation.
The Acoustic Analysis Of Speech presents essential information on modern methods for the acoustic analysis of speech. It assumes only a modest technical background and is intended for the reader who wants to know the basic issues in speech analysis but does not have an extensive background in engineering, physics or mathematics. The book discusses the basic methods for the acoustic analysis of speech in relation to (a) the acoustic theory of speech production and (b) measures of primary interest to speech scientists, speech-language pathologists, linguists, psychologists or others who are interested in the acoustic signal of speech. Readers will gain an understanding of theory, methods and databases pertaining to speech acoustics. The book offers a simple and straightforward explanation of all aspects of acoustic analysis from recording the signal, to analysis methods, to sources of data on phonetic and suprasegmental aspects of speech. Includes reference to acoustic data for several languages in addition to English. The book is written at a general introductory level for course in Speech Science; Speech Acoustics; Experimental Phonetics and Laboratory Instrumentation for Speech and Hearing.

Techniques in Speech Acoustics provides an introduction to the acoustic analysis and characteristics of speech sounds. The first part of the book covers aspects of the source-filter decomposition of speech, spectrographic analysis, the acoustic theory of speech production and acoustic phonetic cues. The second part is based on computational techniques for analysing the acoustic speech signal including digital time and frequency analyses, formant synthesis, and the linear predictive coding of speech. There is also an introductory chapter on the classification of acoustic speech signals which is relevant to aspects of automatic speech and talker recognition. The book intended for use as teaching materials on undergraduate and postgraduate speech acoustics and experimental phonetics courses; also aimed at researchers from phonetics, linguistics, computer science, psychology and engineering who wish to gain an understanding of the basis of speech acoustics and its application to fields such as speech synthesis and automatic speech recognition.
This analysis of speech ranges from clarifying physiological, biological and neurological bases of speech through defining the principles of electrical and computer models of speech production.
This book assembles major writings in speech production and phonetics of the pioneering Gunnar Fant, along with his more recent work on speech prosody. The book reviews the stages of the speech chain, covering production, speech data analysis and speech perception. 19 selected articles are grouped in 6 chapters, including a historical outline plus Speech production and synthesis; The voice source; Speech analysis and features; Speech perception; Prosody.
The accurate determination of the speech spectrum, particularly for short frames, is commonly pursued in diverse areas including speech processing, recognition, and acoustic phonetics. With this book the author makes the subject of spectrum analysis understandable to a wide audience, including those with a solid background in general signal processing and those without such background. In keeping with these goals, this is not a book that replaces or attempts to cover the material found in a general signal processing textbook. Some essential signal processing concepts are presented in the first chapter, but even there the concepts are presented in a generally understandable fashion as far as is possible. Throughout the book, the focus is on applications to speech analysis; mathematical theory is provided for completeness, but these developments are set off in boxes for the benefit of those readers with sufficient background. Other readers may proceed through the main text, where the key results and applications will be presented in general heuristic terms, and illustrated with software routines and practical "show-and-tell" discussions of the results. At some points, the book refers to and uses the implementations in the Praat speech analysis software package, which has the advantages that it is used by many scientists around the world, and it is free and open source software. At other points, special software routines have been developed and made available to complement the book, and these are provided in the Matlab programming language. If the reader has the basic Matlab package, he/she will be able to immediately implement the programs in that platform---no extra "toolboxes" are required.
