Robust Multimodal Interfaces

Alexandros Potamianos
Technical University of CreteAbstractThe talk will touch on four research areas currently underway at the Speech and Dialog group of the Technical Univ. of Crete.namely: multimodal dialogue systems, robust speech recognition, statistical machine translation and automatic induction of semantics from text. Recent work in multimodal dialogue systems focuses on optimizing the mix of input/output modalities based on user preferences and interaction history; the goal is to create adaptive multimodal interfaces (MUSCLE EU project). Recent work in robust speech recognition (under the auspices of the HIWIRE EU project) focuses on feature extraction for ASR under adverse conditions: in this talk, we will present recent research work on feature extraction using the non-linear AM-FM modulation model. Recent work in statistical machine translation focuses on incorporating linguistic knowledge that is automatically extracted (using unsupervised methods) into SMT, e.g., morphological information. Finally, work on automatic induction of semantics from text focuses on using semantic distance measures (based on lexico-syntactic context similarity) to hierarcally cluster words and concepts in taxonomic trees.BiographyAlexandros Potamianos received the Diploma in Electrical and Computer Engineering from the National Technical University of Athens, Greece in 1990. He received the M.S and Ph.D. degrees in Engineering Sciences from Harvard University, Cambridge, MA, USA in 1991 and 1995, respectively. He received the M.B.A. degree from Stern School of Business, NYU in 2002.From 1991 to June 1993 he was a research assistant at the Robotics Lab, Harvard University. From 1993 to 1995 he was a research assistant at the Digital Signal Processing Lab at Georgia Tech. From 1995 to 1999 he was a Senior Technical Staff Member at the Speech and Image Processing Lab, AT&T Shannon Labs, Florham Park, NJ. From 1999 to 2002 he was a Technical Staff Member and Technical Supervisor at the Multimedia Communications Lab at Bell Labs, Lucent Technologies, Murray Hill, NJ. From 1999 to 2001 he was an adjunct Assistant Professor at the Department of Electrical Engineering of Columbia University, New York, NY. In the spring of 2003, he joined the Department of Electronics and Computer Engineering at the Technical University of Crete, Chania, Greece as an associate professor.His current research interests include speech processing, analysis, synthesis and recognition, dialog and multi-modal systems, nonlinear signal processing, natural language understanding, artificial intelligence and multimodal child-computer interaction.Date: March 25, 2005 (Friday)
