I am a professor of linguistics, specializing in phonetics, the science of the speech sounds used in languages.  I have been at UCLA since 1981, and since 1991 I have been the director of the UCLA Phonetics Lab.  On this page you can find out about my current research projects, and also about Mss in Preparation, Publications in Books and Journals, Conference and Working Papers, Talks and Conference Presentations, my CV (including courses taught and former Ph.D. students), and some Personal information.

Research Interests

Most of my current work concerns the voice source. Our NSF-funded project "Linguistic uses of phonation across languages" (with Christina Esposito, Jody Kreiman, Abeer Alwan, and several students/former students) has ended its funding period, though we continue to write up our results. This project concerns the production and perception of phonation types in several languages, with the goal of characterizing the multi-dimensional phonetic space for linguistic voice quality. All speech recordings, analysis results, and software tools from this project (VoiceSauce for acoustic analysis, EggWorks for EGG analysis) can be found on the project website. As an offshoot of this project, I am also interested in the segmental phonetics of Hmong. 

 

Currently, I am part of Abeer Alwan's two NSF-funded projects "A New Voice Source Model: From Glottal Areas to Better Speech Synthesis", which involves high-speech imaging of the glottis, source model development, and perceptual validation; and - new in 2014 - "Variance and Invariance of Voice Quality", which will characterize individual voices in a way that can predict voice confusability. In the future, I will work on applying our methods of voice quality analysis to prosodic structure. I am also investigating acoustic correlates of falsetto and creaky voice.



Past projects have included:

  1. Phonological and speech perception deficits of dyslexic children, with Frank Manis and Mark Seidenberg. We showed that it's the children with more general language difficulties who perceive speech less categorically.  Some of the materials (scripts, files) for experiments conducted in this project are posted here.  See below for publications from this project, the most recent being Bruno et al. 2007, on children's ability to use anticipatory coarticulatory information. 
  2. Optical phonetics (visual speech perception), with Lynne Bernstein at the House Ear Institue and others.  In this project I was especially concerned with the visual perception of optical prosody. Information about the project facilities and some demos are posted at the House Ear Institute website. See below for publications from this project, the most recent being Scarborough et al. 2009, on production and perception of movements of the head, eyebrows, lips, and chin with linguistic prominence. Jiang et al. 2002 demonstrated moderate to strong within-speaker correlations from movements of the face (recorded by motion-capture) to articulatory movements (recorded by EMA), meaning that even movements of the tongue are somewhat "visible" on the face.
  3. How the Prosodic Hierarchy affects consonant articulation (hypothesis: consonants show fortition initially in every domain; this effect is cumulative up the hierarchy).  This was shown to be at least partly so for four languages: English, French, Korean, Taiwanese. Sample data from French and Korean are given on the Phonetics Lab's webpage. See below for publications from this project, the most recent being Cho & Keating 2009 comparing effects of prominence and boundaries.

Courses Taught

Answer to question: Do I have teaching materials on the web?  There are three answers.  First, all undergraduate courses I teach (and some grad courses) have a course website (on CCLE Moodle), and some but not all of the materials I post there are publicly listed and available (some require login with a password).  Second, all materials I prepare on the use of the facilities of the phonetics lab eventually make their way onto that part of the lab's website, which I also maintain: click here. Third, I maintain the lab's Teaching page, which is full of, basically, my ideas.

Personal stuff

I am married to Bruce Hayes, also of the UCLA Linguistics Department. For fun, I used to play viola da gamba; I haven't done that for some years now, but I still keep my membership in the Viola da Gamba Society of America. Now instead I sing Sacred Harp shape-note music with the Westside branch of FaSoLa-L.A., and have my personal Sacred Harp page. I also enjoy English country dancing with the California Dance Coop Los Angeles. As a volunteer, I maintain the Children's Book World's Book Recycling Center.
