I am a now-retired professor of linguistics, specializing in phonetics, the science of the speech sounds used in languages.  I have been at UCLA since 1981, and I was the director of the UCLA Phonetics Lab from 1991 to 2022. I served as department chair from July 2018 through June 2022, and in 2019 completed a 4-year term as President of the International Phonetic Association (IPA). 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

For many years my work has mostly concerned the voice source. Currently, I am part of Abeer Alwan's continuing NSF-funded project "Variance and Invariance in Voice Quality: Implications for machine and human speaker identification" (Information and Intelligent Systems award #1704167). A previous grant in this project funded initial collection of a speech database for comparing voices, and the current grant funded transcription and preparation for public distribution. Currently the database is available here (be sure to find the readme file and the speaker-info spreadsheet at the end of the folder). It is also available from the LDC, at  Using the database, we have begun to characterize individual voices in ways that can predict voice confusability. I am also investigating acoustic correlates of falsetto and creaky voice.


Past projects have included:

  1. Our earlier NSF-funded project "Linguistic uses of phonation across languages" (with Christina Esposito, Jody Kreiman, Abeer Alwan, and several students/former students) ended its funding period a while ago, though we continue to write up our results. This project concerned 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
  2. 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 last being Bruno et al. 2007, on children's ability to use anticipatory coarticulatory information. 
  3. 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. See below for publications from this project, the last 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.
  4. 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 last being Cho & Keating 2009 comparing effects of prominence and boundaries.

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 Culver City ECD (part of the California Dance Coop Los Angeles). As a volunteer, I help maintain the Children's Book World's Book Recycling Center.
