Victor Soto


I am a fourth year PhD student in Computer Science at Columbia University working with Professor Julia Hirschberg. My research interests include Speech Processing and Machine Learning. In the past, I have worked on rescoring strategies for improved Speech Recognition and Keyword Search for Low Resource Languages. Currently I am starting to work on NLP and Speech Processing tools for code-switched corpora. You can find my CV here.
