ABOUT ME
Alfonso Ortega is member of the Aragón Institute for Engineering Research in the School of Engineering and Architecture at the University of Zaragoza, Zaragoza (Spain). He was born in Teruel, Spain and received the Telecommunication Engineering and the Ph. D. degrees from the University of Zaragoza in 2000 and 2005, respectively.
His Ph. D. Thesis, advised by Dr. Eduardo Lleida, received the PhD Extraordinary Award and the Telefónica Chair Award to the best technological Ph. D. In 2006 he was visiting scholar in the Center for Robust Speech Systems (CRSS) of the University of Texas at Dallas, UTD, (USA). He has participated in more than 25 research projects funded by national or international public institutions and more than 15 research projects for private companies. He is author of more than 50 papers published in international journals or conference proceedings and several international patents.
He is presently Associate Professor in the Department of Electronic Engineering and Communications at the University of Zaragoza. His research interests span the areas of digital speech processing, speech enhancement, analysis and modeling of speech and speaker traits, automatic speaker verification, and robust automatic speech recognition. research team in speech recognition and signal processing.
