Current research interests include:

• Pronunciation models for speech recognition
• Statistical investigations of linguistic phenomena in large corpora
• Spoken dialogue system design; spoken human-computer interface issues
• Natural language generation for spoken dialogue systems
• Prediction of errors in ASR systems
• Multi-stream large-vocabulary decoding
• Spoken information retrieval

In the first half of 2003, I was a visiting research scientist at Columbia University in the Electrical Engineering department.

From 2000-2002, I was a researcher at Bell Labs, Lucent Technologies, in Dialogue Systems Research Department (later, the Multimedia Technologies Research Department), where I worked on spoken dialogue system research within the DARPA Communicator program.

I was a post-doctoral researcher for 1999-2000 at the International Computer Science Institute (ICSI), in Berkeley, California. A 1999 graduate of the Computer Science department at UC Berkeley, my dissertation research was concerned with dynamic models of pronunciation within automatic speech recognition systems. This research was conducted within the Realization Group at ICSI; click here for a further description of my dissertation work.

I recently co-organized the ISCA Tutorial and Research Workshop on Pronunciation Modeling and Lexicon Adaptation for Spoken Language Technology
