An innovative text that covers both synthesis and recognition of speech, by an acknowledged expert. It is written for undergraduate and graduate students of computer science, electronics and information technology, and will be a very useful reference for practising engineers who need to specialise in speech technology. Worked examples, problems, chapter objectives and summaries and a full bibliography are included. The material is highly topical including speech synthesis from stored human speech, speech synthesis by rule and speech recognition of whole words, plus a complete chapter on digital coding of speech and a full discussion of the basic principles, mechanisms and models involved. This book should be of interest to second and third year undergraduates in computer science and electrical/electronic engineering; undergraduates and postgraduate students of information technology; engineering and computing professionals.
