Khia A Johnson

I'm a PhD candidate in linguistics at the University of British Columbia with Dr. Molly Babel. I study phonetic variation in bilingual speech production and comprehension, with an eye towards big picture questions about processing and representation. My dissertation research focuses on how similar segments are represented in Cantonese-English bilingual speech. I'm also interested in socially conditioned variation, especially as it relates to non-native accents and multilingual identities. I think it's important to connect research outcomes to practical applications in areas like technology and education. I am part of the UBC Public Scholars Network.

current projects

cantonese-english bilingual speech corpus

I'm developing a conversational corpus of Cantonese-English bilingual speech with sufficient audio quality for phonetics research, as part of my dissertation research. It be made publicly available in the future. I talked about the project on April 26, 2019 as part of the PhDs Go Public series at the Vancouver Public Library. I'll be presenting a pilot study on cross-language influence in sibilant production in Cantonese-English bilingual speech at the ASA meeting in San Diego, CA on December 3, 2019.

perceptual learning

I work on a few different perceptual learning projects in the Speech-in-Context lab—testing the paradigm online, and exploring cross-language transfer in different permutations. I'll be presenting a web replication study at the ASA meeting in San Diego, CA on December 3, 2019.

probabilistic reduction in spanish-english bilingual speech

I presented this work at the International Congress of Phonetic Sciences in Melbourne, Australia on August 8, 2019. You can find the full paper here.
