PhonLinks

Phonetics is a practical science that involves study of vocal tract movement, air flow, sound waves, and perception of sound by the ear. All of these phenomena are well suited to demonstration on the world wide web.

 This page contains links to web sites that have excellent demos of the various aspects of phonetics. For the most part, the list of links follows the order of presentation in Peter Ladefoged's A Course in Phonetics, which is now also supported by its own website (Peter Ladefoged's Vowels and Consonants), and for the fifth edition, its own CD-ROM. There's also a list of more general linguistics information resources at the end of this list.

Many of the topics listed below contain alternate keyword suggestions in square brackets if you want to search the web for more information. If you locate a site that looks like it belongs on this list, please let me know at fitzpatricke@mail.montclair.edu.
