Biography:

Dr. Chalapathy Neti is a Research Staff Member in the Human Language Technologies department at IBM Research. He is currently leading a research effort that he initiated on audio-visual speech technologies. In this role, he is leading a group of researchers in developing algorithms and technologies for joint use of audio and visual information for robust speech recognition, speaker recognition and multimedia content anlaysis and mining. He recently led a 6 week long workshop (July-Aug, 2000) on audio-visual speech recognition at the Center for Language and Speech Processing (CLSP), Johns Hopkins University.

Dr. Neti's main research interests are in the area of perceptual computing (using a variety of sensory information sources to recognize humans, their activity and intent), speech recogntion, multi-modal conversational systems for information interaction and multimedia content representation for easy access.

Prior to the work on audio-visual recognition technologies, he was a key member of the team responsible for the speech recognition component of  spoken language systems for the Air Travel Information System (ATIS), Bilingual (English and French) ATIS, Mutual Fund transactions and the audio-indexing application. He was also responsible for the telephone access component of the Conversational Assistant project (multi-client multi-modal access to mail and calendar): a Research Divison milestone for 1999. He was given a Research Division Technical Group award for this project. He has developed algorithms related to confidence estimation, accent and language independence and noise-robust speech representations based on the mammalian auditory system. 

Before moving to IBM Research, he joined  IBM Boca Raton (1990) as an Advisory Scientist, where he worked on optimal algorithms for PC design; participated in a corporate wide study (organized by the Academy of Technology) of data compression technologies to define IBM's development and organization strategy; was a liaison to University of Notre Dame to define and drive collaborative research in cluster computing using PCs and other workstations. 

He has authored over 25 articles in these fields and has 5 patents and several pending. Dr. Neti received his Ph.D. degree in Biomedical Engineering from The Johns Hopkins University, and his Master's degree in Electrical Engineering from Washington State University, and his Bachelor's degree in Electrical Engineering from the Indian Institute of Technology at Kanpur. He has been with IBM since 1990. He is currently a member of the IEEE Multimedia Signal Processing Technical Committee and is an associate editor of the IEEE Transactions on Multimedia.
