Anna Choi

I’m currently a 4th-year Ph.D. candidate in Information Science at Cornell University, working with [Professor Allison Koenecke](https://koenecke.infosci.cornell.edu/). I started out my Ph.D. journey in the Linguistics Department, where I mostly worked with Professor Mats Rooth and Professor Sam Tilsen, and then transferred at the end of my 2nd year to Information Science. I still keep ties with the Linguistics by working for a minor degree. I’m currently affiliated with University of Pennsylvania as a Visiting Scholar at Linguistic Data Consortium, working with [Professor Sunghye Cho](https://www.sunghyecho.com/home).

I work in the intersection between AI Ethics and Automatic Speech Recognition. I have two main research interests: **(1) Auditing Speech-to-Text algorithms** and **(2) Using voice as biometrics in AI for Healthcare**. I work with diverse speech datasets to test for algorithmic fairness in ASR models and critique evaluation methods, both in terms of the technical aspect and the social and legal aspect. Because I work with speech data from population with health impairments, I analyze their acoustic features in an attempt to utilize voice as a biometric. I focus on diagnosis of their state in terms of severity, especially focusing on neurodegenerative disorders such as Alzheimer’s Disease, Schizophrenia, and Aphasia, among many others.
