My research interests include natural language processing and speech recognition. I am currently working on hedge detection in the Supreme Court corpus, where we are trying to find reliable acoustic correlates of hedging and uncertainty. Ultimately, I am aiming to explore the relationship between hedging and the power structure of a conversation, as well as the various other social outcomes of dialogue. Previously, I have worked on the sociolinguistics of /tr/ affrication in Canadian speech, the phonetics of singing and various ASR training paradigms.
