Newly revised and expanded, Acoustic and Auditory Phonetics provides readers with an accessible yet rigorous introduction to phonetics and speech sciences. The first chapters introduce basic acoustics, audition, signal processing, and the acoustic theory of speech production. The book then surveys the major classes of sounds, describing them acoustically, auditorily, and perceptually. This second edition includes a new chapter on speech perception and additional sections on digital filtering and cross-linguistic vowel and consonant perception. The successful first edition received high praise, and the enhancements to the second edition make it an even more valuable resource for students.
