My primary research interest is the French schwa (also known as the e-muet or the e-caduc.) This is the <e> that can be deleted in everyday speech in French (ie. un cerisier ~ un c'risier ; une fête ~ une fêt' ; rappeler ~ rapp'ler). My research employs large amounts of data to work toward a purely phonological redefinition of the e-muet. I am interested in this phenomenon from four distinct points of view.
Sociolinguistics -- Since language is a primarily social phenomenon, what social factors condition the realization of schwa and how do they do so? Geographical factors are well-documented predictors of schwa realization, but what other social factors are? Are deletion and epenthesis sociolinguistically affected in the same way? And how do these sociolinguistic factors interface with phonological factors?
Deletion -- Under what contexts and situations can this vowel be deleted? How does the deletion of this vowel affect the syllables near it? Why is it this vowel in particular that can be deleted: what makes it 'weak'?
Epenthesis -- When can we add this vowel in everyday speech? Only for hesitation? What about the trends of primarily upper-class, female speakers in Paris that seem to add this vowel before a pause (ie. Bonjour-uh!)? How does the addition of this vowel in speech interact with the deletion of other consonants (ie. un arbre vs. un arbr' vs. un arb')?
L2 Learners -- Finally, how do learners of French learn when this vowel can be deleted and can be epenthesized? More specifically, are they able to effectively conceptualize and form a representation of a 'moving target' in the speech signal or in the language classroom? Is schwa realization 'sociophonologically' conditioned for learners as it appears to be in the speech of native speakers?
I am also interested in the use of large-scale corpora for both their research and pedagogical implications. Part of my dissertation research focuses on the cleaning and further specification data in the PFC corpus. More specifically, what can large amounts of data tell us about phonological variation? Corpora are also valuable pedagogical tools. How can language teachers incorporate large-scale oral corpora into their syllabi, specifically to improve and instruct pronunciation and practical phonetics? Future research projects will include fieldwork to modernize the corpus as well as add survey points of under-documented varieties of French.
This research program investigates a subset of data from Prof. McBride's research program on the phonetics of nasal vowels in native speakers of French as well as learners of French. We are interested in a previously undocumented phenomenon: the deletion of the nasal vowel in the possessive adjective son (ie. son appartement ~ sn'appartement.) What exactly are the phonetics of this elidable vowel as well as the phonological contexts which may condition the zero realization of this vowel?
Prof. Renwick has conducted extensive research on the marginal contrast in the mid-vowel systems of regional varieties of Italian. Our work together is looking at how we can formalize her findings in a maximum entropy grammar making use of scaled constraints as a means of incorporating the phonetic factors that largely influence a speaker's realization of /e/ and /o/. We are also applying her initial methodology to the mid-vowel system of Parisian French and formalizing these results with the hopes of exploring similarities between these equally complex vowel systems.
