Offering the most current coverage available, A COURSE IN PHONETICS, 7e remains the authoritative text for the study of phonetics. Combining Peter Ladefoged's student-friendly writing style with Keith Johnson's comprehensive presentation, the Seventh Edition introduces concepts of speech production, describes speech in acoustic terms, and teaches practical phonetic skills including IPA transcription. Expanded sections on acoustic phonetics and speech motor control bring instructors up to date and help students use tools for digital inspection and manipulation of speech. Numerous updates include MRI images of vocal tracts. In addition, the thoroughly revised companion website includes interactive exercises, instant spectrograms for every chapter, over 4,000 audio files of nearly 100 languages, and maps keyed to sounds of languages where they are spoken.
