Chitralekha Gupta

I am a fourth year PhD student in NUS Graduate School for Integrative Science and Engineering associated with the Department of Computer Science at National University of Singapore. I am working with A/Prof. Wang Ye and Prof. Li Haizhou as my advisors.

My research interests are speech and music signal processing, music information retrieval, and applications of music in education and health therapy. I am currently working on automatic evaluation techniques for speech and singing voice signals.
