Current Research
I have been working on the Let's Go! project with my advisor, Dr. Alan Black, since September 2002. This project involves building a spoken dialog system for bus information that can be readily used by non-native English speakers and the elderly, as well as the general population.
My current research interests are in natural language generation and speech synthesis. Specifically, I have been researching how to improve the quality of speech synthesis so that it is clear and natural enough to be understood by users of speech systems, which includes populations that typically have difficulty understanding synthesized speech. This includes work on stylistic changes in spoken output as well as exploring improvements in presenting complex information using speech. Recent work has been in investigating what makes spoken output understandable, and how to apply that to langauage generation for synthetic speech.
