Research Interests

As a sociophonetician, my research concerns variation in speech-sound production and perception (both linguistic and social). I have investigated prosodic features of stance (how intonation conveys attitudes/opinions), a vowel merger in Pacific Northwest English (where "bag, egg, vague" can rhyme), and the social effects of the speech intelligibility of deaf people who use cochlear implants (how well their speech is understood and how that affects social perceptions of them).
