I am a PhD student at McGill Linguistics, affiliated with the Centre for Brain, Language, and Music and the Speech Learning Lab with Prof. Meghan Clayards. I am interested in how language experience shapes speech perception and production, and whether the two modalities are linked at the phonological level or the acoustic-phonetic level. I use behavioral data and computational modeling to reveal when and how speech learning occurs. I also worked on speech prosody and second language acquisition. With Prof. Zhen-Hua Ling, I modeled L2 prosody in the ToBI scheme using neural networks. I investigated how dialect experience affects English stop acquisition between Mandarin and Wu children collaborating with Prof. Jian Hu. I also worked with Prof. Ziyu Xiong and Prof. Aijun Li in terms of L2 speech corpora studies.

Research

I seek for behavioral and computational evidence to answer questions regarding language and speech.

The Link Between Speech Perception and Production

Successful communication requires a symmetric relationship between speech perception and production. We attempt to reveal how the two modalities synchronize during speech learning.

Prosodic Event Detection for L2 Speech

In linguistics, prosody refers to properties of syllables and larger units of speech, including linguistic functions such as intonation, stress, and rhythm. We relied on statistacal learning algorithms to find L2 prosody patterns.

Dialect Effect on Language Learning

Chinese, also known as Sinitic, is a branch of the Sino-Tibetan language family consisting of hundreds of local varieties, many of which are not mutually intelligible. We are interested in how Chinese dialect affects English learning.
