I am a CS Master's student at Columbia with a concentration in NLP, and work as a research assistant in the speech lab. My current research involves studying deception. The goal of this research is to identify acoustic, prosodic, and lexical features of speech linked with deceptive behavior. Ultimately, we hope to develop a framework for automatically detecting deception in speech. I previously worked on TTS for low resource languages - scraping text data from blogs, training voices, and evaluating the naturalness of synthetic voices using crowdsourcing platforms.
