Phonetic Analysis of Speech Corpora

• Gebundenes Buch

Produktbeschreibung

The Phonetic Analysis of Speech Corpora introduces methods of analyzing phonetically-labelled speech corpora, with the goal of testing hypotheses that often arise in experimental phonetics and laboratory phonology. The book begins by discussing some of the techniques in digital speech processing and in structuring and querying annotations from speech corpora. The second half of the book focuses on analysis, including measuring gestural synchronization using electromagnetic articulometry (EMA), the acoustics of vowels, consonant overlap using electropalatography (EPG), spectral analysis of fricatives and obstruents, and the probabilistic classification of acoustic speech data. Each chapter has an extensive set of exercises, with answers to reinforce the techniques introduced. An overview of the necessary software tools, including the R programming language, enables the reader to duplicate the stages of analysis computationally. Clearly laid out, with easy-to-follow computer commands, spectrograms of speech corpora, and a companion website with more illustrations and downloadable speech corpora for testing purposes, this book is a complete resource for the research increasingly conducted in phonetics.

Autorenporträt

Jonathan Harrington is Professor of the Institute of Phonetics and Speech Processing (IPS), University of Munich, Germany. His recent research has primarily focused on modelling the acoustic and perceptual mechanisms of sound change. He is co-editor of Speech Production: Models, Phonetic Processes, and Techniques (with Marija Tabain, 2006) and Techniques in Speech Acoustics (with Steve Cassidy, 1999).

Rezensionen

"The book undoubtedly succeeds entirely in its goal to provide anaccessible and effective practical introduction to using Emu speechdatabase system and Emu-R functions to analyze phonetic data. It iswritten in a clear and accessible language and the topics areintroduced in a coherent and easy to follow manner with thecomplexity of the material gradually increasing from the beginningtowards the end of the book. Even rather complicated concepts aremade easy to understand with an exceptional use of analogy and acommendable restraint from going into too many mathematical andtechnical details...this is a well-written, well-structured,easy-to-follow workbook which boasts an excellent set of practicalexercises and demonstrations and covers a wide range of techniques.Overall, those readers who have a basic background in phonetics andstatistics and are prepared to work their way carefully throughthis book will be greatly rewarded with its informativeness andeffectiveness."
