Since the mid-1980s, Homayoon Beigi has conducted research and development in the fields of Biometrics, Optimization, Pattern Recognition, Machine Learning, and Internet-Commerce. His work, as the President of Recognition Technologies, Inc., has included research and development, leading to the production of a series of Speaker Recognition, Speech Recognition, Face Recognition, and Signature Recognition software engines. He is the author of the first and only textbook on speaker recognition, "Fundamentals of Speaker Recognition."
In addition, since 1995, he has been an Adjunct Professor, at the Computer Science department, as well as Mechanical Engineering and Electrical Engineering departments of Columbia University , he has been teaching the following graduate courses, "Fundamentals of Speaker Recognition (COMS-E6998-005)," "Fundamentals of Speech Recognition (COMS-E6998-004)," "Digital Control Systems (EEME-E4601y)," "Applied Signal Recognition and Classification (ME-E6620y)", and "Speech and Handwriting Recognition (EE-E6820x)," which was also being distributed in Video through the Columbia Video Network.
Homayoon Beigi is also actively involved in several standards bodies. He has been an active liaison in the US delegation of the ISO/SC37-JTC1-WG3. He has also been a active liaison and the driving force behind the Audio Format for ANSI/INCITES M1 (Biometric Data Interchange Format) committee. In addition, he has been an active liaison in the VoiceXML Forum committe on Speaker Biometrics.
Homayoon Beigi received his Bachelors, Masters, and Doctorate degrees from the Department of Mechanical Engineering at Columbia University in 1984, 1985 and 1990 respectively. His Doctoral thesis was on Learning Control and Neural Network Learning. He worked on lossless image compression at the Center for Telecommunication Research at Columbia University for 6 months after receiving his Doctorate degree and then joined the Handwriting Recognition Group at IBM T.J. Watson Research Center, followed by the Speech Recognition Group in New York in February of 1991 where he held the position of Research Staff Member until February of 2001 working on Handwriting, Speaker and Speech Recognition research problems in depth. At the present he is the President of Recognition Technologies, Inc. in Yorktown Heights, NY and the Vice President of Internet Server Connections, Inc., White Plains, NY. In addition, he holds a position as an Adjunct Professor at the School of Engineering of Columbia University.Homayoon Beigi has been the recipient of two best paper awards from the Institute of Electrical and Electronic Engineers (IEEE) for his work in Neural Network Learning. He has been an Associate Editor of the Intelligent Automation and Soft Computing Journal , the Editor for the handwriting recognition chapter of the Berkeley Initiative in Soft Computing , and an Executive Committee Member of the Society for Technological Advancement in Developing Countries. He is also a Senior Member of the IEEE and a member of the Advisory Board Committee of the IEEE Spectrum Magaznie. At IBM Research, he worked on all aspects of Multimedia Search, speech, speaker and handwriting recognition research such as architecture, preprocessing and front-end, classification, search, language models, training, etc. He has also been actively conducting research in Control Theory and Neural Network Learning.
