Horacio Franco - SRI International

Chief Scientist, Speech Technology and Research Laboratory (STAR)

Horacio Franco is chief scientist in the Speech Technology and Research Laboratory at SRI International. Since joining SRI in 1990, he has contributed in the areas of acoustic modeling, hybrid Hidden Markov Model (HMM)-neural net speech recognition approaches, speech recognizer architectures, speech technology for language learning, noise-robust speech recognition, and speech-to-speech translation systems.

He has co-authored more 70 papers, as well as several communications and book chapters. Franco is co-author of several U.S. patents in aspects of speech recognition, speech technology for language learning, and noise-robust speech recognition. He has also been active in leading efforts to develop and deploy SRI’s speech technology in different areas of government and commercial use.

Franco received his engineer’s degree in electronics in 1978, and his doctor in engineering degree in 1996, both from the University of Buenos Aires.
