Phonetics, Speech and Hearing
- Speech Internet Dictionary - from UCL. Definitions of technical terms used in phonetics, phonology, speech and hearing science and allied disciplines.
- Sound waves - from the University of Manitoba
- Department of Speech, Music and Hearing at the Royal Institute of Technology, Sweden
- Real time spectrogram - from Royal Institute of Technology, Sweden. (online spectrogram includes link to required Snack 16 plug-in)
- Spectrogram reading - (in German) from the Institut für Phonetik und Sprachliche Kommunikation, Universität München
- The vOICe Sonification Applet - from the Philips Research Laboratories, Eindhoven, The Netherlands
- Sound to Graph to Sound with JavOICe - Spectrogram version of preceding site
- Airstream Mechanisms and Phonation Types - Ladefoged's clicks, ejectives, etc. in many languages
- Airstream mechanisms - from Northwestern University
- Types of phonation: creaky, breathy, harsh, falsetto - from the University of Stuttgart
- Gas-altered perceived voice pitch:
- Helium Voice - from Ask Yahoo (linked to sound file with poor audio quality, but someone may ask about the 'Donald Duck' effect of helium)
- Sulfur Hexafluoride Voice - from the University of Maryland
- Bucknell University (PA): Links to pages on lots of linguistics-related topics
- Acoustic cues in differentiating phonemes - from UCL. Isolating acoustic cues in phoneme recognition; descriptions, sound files; good companion to chapter 11 of Fry (see (6)).
- Simplified Vowel Synthesis Interface - from the University of Delaware. Synthesize non-nasalized monopthongal English vowels using the Klatt synthesizer. Set F0, F1, F2, and duration in ms yourself, and see what you come up with. Links to more complex CV synthesis and general synthesis interfaces.
- Zona Land - by Ed Zobel. Excellent interactive tutorials on the physics of waves (with links to other physics topics); I find them to be well-matched companions to D. B. Fry's The Physics of Speech (Cambridge). Example of things you can do at this site: draw two waves yourself then watch how they interfere with each other. VRML plug-in required for some parts. Highly recommended.
- The Physics Classroom: Sound Waves and Music - from Glenbrook South High School. A good physics tutorial site with units on waves and decibels; this has dense and very instructive explanatory texts, along with animated graphics.
- Standing Waves and Sound - from Concordia College. Samples of some audible frequencies (100 to 5,000 Hz), along with other information on waves.
- Understanding decibels - from the Handbook for Acoustic Ecology, Cambridge Street Publishing, 1999. Web version from Simon Fraser University. Technical but clear and potentially useful. With sound files.
- Sound Pressure Levels - from CoolMath.com. Decibel level list
