Victor Soto

 

I am a second year PhD student in Computer Science at Columbia University working with Professor Julia Hirschberg. My research interests include Speech Processing and Machine Learning. Currently I am working on rescoring strategies for improved Speech Recognition and Keyword Search for Low Resource Languages. You can find my CV here.
