Dr. Stephen Winters’ work focuses on the perception of speech, primarily from an exemplar theory-based point of view. Recently, he has worked with students on the perception of the “source” features of speech, including intonation, tone and voice quality. He has also collaborated with students on the development of exemplar-based computational models of lexical tone and intonation perception.

The Phonetics Lab is the center of research on the perception and production of speech sounds at the University of Calgary. It houses a wide variety of technologies for the production of high quality audio and video, for running experiments, and storing data. Visit the Phonetics Lab website for more information.

The Phonetics/Phonology Reading Group

The phonetics/phonology reading group meets weekly to discuss recently published work and ongoing research in phonetics and phonology. Previous topics of discussion have included prosody, phonation, acoustic phonetics, and automatic speech recognition, among others.
