Short CV

Yannis Stylianou is Professor at University of Crete, Department of Computer Science, CSD UOC and Visited Researcher in the Networks and Telecommunications Laboratory of the Institute of Computer Science ICS at FORTH. He received the Diploma of Electrical Engineering from the National Technical University, N.T.U.A., of Athens in 1991 and the M.Sc. and Ph.D. degrees in Signal Processing from the Ecole National Superieure des Telecommunications, ENST, Paris, France in 1992 and 1996, respectively. From 1996 until 2001 he was with AT&T Labs Research (Murray Hill and Florham Park, NJ, USA) as a Senior Technical Staff Member. In 2001 he joined Bell-Labs Lucent Technologies, in Murray Hill, NJ, USA (now Alcatel-Lucent). Since 2002 he is with the Computer Science Department at the University of Crete and the Institute of Computer Science at FORTH.

His current research focuses on speech signal processing algorithms for speech analysis, statistical signal processing (detection and estimation), and time-series analysis/modelling. He has (co-)authored more than 100 scientific publications, and 9 US patents, which have received in total more than 1800 citations according to Google Scholar with H-index=20. He co-edited the book on “Progress in Non Linear Speech Processing”, Springer-Verlag, 2007. He has been the P.I. and scientific director of several European and Greek research programs and has been participating as leader in USA research programs.

Among other projects, he is currently P.I. of the FET-OPEN project LISTA: “The Listening Talker”, where the goal is to develop scientific foundations for spoken language technologies based on human communicative strategies. In LISTA, he is charged of speech modelling and speech modifications in order to suggest novel techniques for spoken output generation of artificial and natural speech.

He has created a lab for voice function assessment equipped with high quality instruments for speech and voice recordings (i.e., high-speed camera) for the purpose of basic research in speech and voice, as well for services, in collaboration with the Medical School at the University of Crete.

He is on the Board of the International Speech Communication Association (ISCA), member of the IEEE Speech and Language Technical Committee and of the IEEE Multimedia Communications Technical Committee. He is on the Editorial Board of Journal of Electrical and Computer Engineering, Hindawi JECE, Associate Editor of the EURASIP Journal on Speech, Audio, and Music Processing, ASMP, and of the EURASIP Research Letters in Signal Processing, RLSP. He is Vice-Chairman of the Cost Action 2103: "Advanced Voice Function Assessment", VOICE. He was Associate Editor for the IEEE Signal Processing Letters and on the Management Committee for the COST Action 277: "Nonlinear Speech Processing".
