Web Resources

• The International Phonetic Alphabet (IPA) – the Omniglot website has a section that describes the full range of symbols. 
• Haskins Laboratories – associated with Yale University, Haskins has been at the forefront of language research for decades, including speech perception and prosody, reading and literacy, and brain bases of language. Check out their demonstrations, including a remake of early speech synthesis. 
• The National Center for Voice and Speech (NCVS) – a multi-site collaboration aimed at sharing research and educational information about speech and the voice, and to enhance clinical services for those with voice problems. There are several tutorials, including one on spectrograms.
• If you’re interested in phonetic analysis, spectrograms, or editing sound files, there are some free programs you can try out. A more general purpose program is Audacity. If you are somewhat comfortable with downloading and installing software, and consulting a user manual or FAQs to get started, two more specific programs you can look into are Praat and Wave Surfer.
• An online web experiment illustrating categorical perception. (Java plug-ins will need to be up to date.)
