I am a researcher in the Speech and Dialog Research Group at Microsoft Research, working at Microsoft’s Silicon Valley Campus. My interests include speech recognition and understanding, language modeling, speaker recognition, language and dialect recognition, machine translation, historical linguistics, and software tools for computational linguistics. I am also an External Fellow at the International Computer Science Institute (ICSI) in Berkeley, where I lead a joint project with Microsoft.
Prior to 2011, I worked in the Speech Technology and Research Laboratory at SRI International, mainly on government-funded research projects in speech recognition, speaker recognition, and machine translation, such as the DARPA projects EARS, GALE, and RATS. While at SRI, I also collaborated with ICSI on recognition of multiparty meetings and other projects, and developed the open-source SRI Language Modeling Toolkit.
My Ph.D. research was in Computer Science at the University of California, Berkeley, on parsing and Bayesian learning of stochastic grammars.
