Research Interests

Between August 1994 and October 2001 I was a member of the Experimental Phonetics group at the Institute of the Institute of Natural Language Processing (IMS), University of Stuttgart. My main research interest is speech synthesis. I am responsible for the development of the IMS German Festival system, a complete Text-to-speech system based on Festival technology. In my dissertation I worked on prosodic aspects of speech synthesis including a trainable parametric model of intonation prediction. Until 2001 I was coordinating the speech output module within the SmartKom project, a German government founded project dealing with multimodal human-machine interaction.
