Effects of Linguistic and Indexical Sources of Variation on Speech Processing
My primary research interest is the role of variation in spoken language processing. One branch of my work in this area, supported by the National Science Foundation (BCS 1056409), explores the interaction between phonetic reduction, dialect variation, and linguistic sources of variation, including lexical competition and semantic context, in speech production and perception. The other branch examines the effects of experience with linguistic variation on cross-dialect speech perception and processing. Many of my experiments involve speech samples from The Nationwide Speech Project Corpus.
Perception of Socio-Indexical Information Across the Lifespan
In collaboration with Dr. Laura Wagner in the Department of Psychology at Ohio State, I have extended my earlier work on perceptual dialect classification to children as young as four years old. Our research uses explicit classification, language attitudes, and cross-dialect intelligibility tasks to explore when children perceive and interpret information in the acoustic speech signal to make judgments about social categories, such as region of origin, and how the perception of regional dialect variation changes over the course of the lifespan. The results of this project are available on the ORDDR Project website. (Partially supported by a Seed Grant from the Ohio State Center for Cognitive and Brain Sciences).
Prosodic Variation in American English
In collaboration with Dr. Rajka Smiljanic in the Department of Linguistics at the University of Texas, I am working on an examination of regional prosodic variation in American English, including intonation and temporal organization. (Partially supported by a Coca-Cola Critical Difference for Women Faculty Grant).
The Prosody of Focus in Un(der)-described Languages
In collaboration with Dr. Judith Tonhauser in the Department of Linguistics at Ohio State, I am exploring the prosody of focus in Paraguayan Guarani, Moroccan Arabic, and K'iche' Mayan. Paraguayan Guarani, Morocccan Arabic, and K'iche' Mayan are typologically diverse with respect to their prosodic structure and therefore provide the opportunity to extend the description and theoretical treatment of focus and the prosody-meaning interface to non-Germanic languages.

Research Opportunities for Undergraduates
|Undergraduate research assistants are always welcome in Cynthia Clopper's Speech Perception Lab. Students can earn credit in 4998(H) (Undergraduate Research) for work in the lab. Paid positions are also sometimes available. Students do not need to be a linguistics major to work in the lab, but some coursework in linguistics or a related field (speech and hearing science, psychology, cognitive science) is preferred. If you are interested in working on any of the projects described above, please contact Cynthia Clopper to discuss research opportunities.|

When I'm not doing research, I enjoy traveling. My most recent travel adventures have taken me to Glasgow, Aix-en-Provence, and Maine.
I'm also a college basketball junkie. I follow Duke basketball with a passion, but I'll watch pretty much any game at the college level.
