About me

top of page «
I am a research scientist at Haskins Laboratories at Yale University. I am a phonetician and a fieldworker who works on speech production, language documentation, and corpus phonetics. My phonetic research focuses mainly on suprasegmental contrasts (tone, length, phonation, stress, prosody). This includes all aspects of tone production, but I have particular interests in the production and perception of tonal cues, in how prosody and tone interact, and in the relation between voice quality (phonation) and tone. In addition to my phonetic work, I am interested in linguistic description, morphophonology, and applying computational methods to process speech in corpora.

I investigate these topics in different Oto-Manguean languages, which are all indigenous languages spoken in Mexico (and incidentally, Oto-Manguean is the largest language family in the Americas). These languages interest me partly because they have the most complex tonal systems found anywhere in the world (with up to 12 tones on a single unit), they have complex segmental inventories, and they have complex grammatical processes involving these things as well. Some of the patterns found in these languages push the limits of what we believe is possible in any human language. If we are to take seriously the idea that linguistic theories are theories of language and not languages, then we have to test such theories on a diversity of languages. Since 2004, I have done fieldwork on San Martín Itunyoso Triqui, a Trique language spoken in the Mixteca region of Oaxaca, Mexico. In Fall 2009, I began collaborating on fieldwork on the Ixcatec language, a moribund language in Oaxaca, Mexico with only a few remaining speakers. In Fall 2010, I began collaborating on fieldwork on Yoloxóchitl Mixtec, a little-described language in San Luis Acatlán, Guerrero, Mexico. This latter project is funded by the National Science Foundation with linguist Jonathan Amith (Gettysburg College) as the principle investigator and Rey Castillo (CIESAS) as collaborators.

I am funded through two NSF grants. The first grant (DiCanio, PI), Understanding Prosody and Tone Interactions through Documentation of Two Endangered Languages involves the investigation of the prosody-tone interface in Itunyoso Triqui and Yoloxóchitl Mixtec, the development of computational tools for speech segmentation in each language, and text documentation. The second grant (Whalen, Xu (PIs)), A Common Prosody Platform for Testing Theories and Models of Speech Prosody involves creating and testing models of prosody with pitch data from a diverse set of languages. This includes intonational data from English and Greek as well as lexical tone data from Mandarin and Itunyoso Triqui.
