Stefan successfully defended his Ph.D. degree at the Sound Analysis/Synthesis Team of IRCAM within the context of Voice Transformation and Voice Conversion in September 2015. He was initially financed by the ANR CIFRE contract no. 2011/2011, a former collaboration between the research institute IRCAM and the company Acapela Group. Then he was financed by a grant from the ANR Project ChaNTeR to develop a synthesis system for high quality singing voices. His research interests include analysis-transformation-synthesis for spoken and sung voices as well as Statistical and Digital Signal Processing for audio and music. He is currently working as a freelance consultant, comitting his knowledge as Speech Scientist to the relevant industry.
