About me
Manager & Research Staff Member
Dept. of Speech-to-speech Translation
Research lab: Watson Research Center (Yorktown)
I am a research manager and Research Staff Member with the IBM Thomas J. Watson Research Center, Yorktown Heights, NY. I have been managing the Dept. of Speech-to-Speech Translation, starting from 2008. I am currently a Principal Investigator in the DARPA TRANSTAC Program. In these roles, I am responsible to lead a world-class research team to advance end-to-end speech-to-speech translation technologies, including automatic speech recognition, machine translation, and text-to-speech synthesis. Our team creates the MASTOR (multilingual automatic speech-to-speech translator) system, a two-way, real-time, free form conversational speech translation solution.
My research interest spans a variety of topics in computational speech and language processing, including automatic speech recognition (ASR), statistical speech-to-speech translation, natural language processing, spoken language understanding, spoken information retrieval, and machine learning.
My recent work includes an improved formal syntax statistical machine translation (SMT) system (a.k.a. ForSyn) with bilingual chart parsing and tree kernels, a framework for multiple-graph based SMT with a multi-dimensional Viterbi decoder (a.k.a. Folsom), and joint ASR and SMT decoding using this framework, and an integrated end-to-end S2S system on handheld platforms. My prior work includes rapid speaker adaptation for large vocabulary continuous speech recognition, a spoken document retrieval system (a.k.a. SpeechFind), and audio parsing. More about my research can be found from My Publications .
I have been actively served as technical reviewers for a number of major academic journals and international conferences in the fields of speech, signal and natural language processing, including the IEEE Transactions on Audio, Speech and Language Processing, the IEEE Signal Processing Letters, Computer Speech and Language, the journal of Speech Communication, EURASIP, and the InterSpeech (ICSLP and EuroSpeech), ACL, NAACL, HLT, COLING, ICASSP, ASRU, SLT, EUSIPO etc. I also served as a committee member for professional workshops in related areas.
I received the B.E. degree from the University of Science and Technology of China in 1996, the M.E. degree from the Chinese Academy of Sciences in 1999, and the Ph.D. degree from the University of Colorado at Boulder in 2003, all in Electrical Engineering.
