Since Malmberg's classic Manual of Phonetics published in 1968 there has been no definitive up-to-date account of the phonetic sciences. The Handbook of Phonetic Sciences is unique in that it brings together, in the same volume, chapters on the biological foundations of speech and hearing such as brain functions underlying speech, organic variation of the vocal apparatus, auditory neural processing, articulatory processes together with chapters on theoretical and applied areas.
