Key Features Keith Johnson, a leading phonetician, has revised the material on acoustic phonetics to incorporate developments in technology and research and offer students more opportunities to apply new knowledge. Acoustic analysis is introduced in early chapters with spectrograms of English and non-English speech sounds so that students can use their high levels of computer literacy to perform analysis from the start. Images of MRIs and X-ray data have been added, providing students with more visual images of the articulatory organs (tongue, velum, etc.) and the airflow when humans produce sounds. The Sixth Edition features an extensively revised final chapter on linguistic phonetics to help students understand the relationship between phonetics and phonology, the principles of the IPA, and phonetics of the community vs. phonetics of the individual. The accompanying CD-ROM is updated to include new chapter exercises to coincide with those in the book, new sound files, and a more streamlined navigation and appearance. All of the sound files have also been converted to a more widely used format. The CD included with and keyed to the text has over 4,000 recordings of Englishes and other languages, maps of language areas, exercises and tables in the text, and so on. Demonstrations of the phonetic performance exercises are provided, and most exercises can be downloaded and printed. Also includes recordings of British and American English for transcription exercises; speech samples for Southern (U.S.) and Northern (U.S.) cities; and recordings of London, Edinburgh, Dublin, New Zealand, and other forms of English. Extras on the CD include map indexes and recordings of the IPA chart sounds and many other languages. This text offers a broad overview of phonetics for students with no prior knowledge. A COURSE IN PHONETICS is a comprehensive, straightforward account of the major aspects of the phonetics of English and the major features of the sounds of the world's languag
