Phonetics deals with the production, acoustics and perception of speech sounds. Phonology examines the functional aspects of sounds in communication, e.g. which sounds out of the many possiblearticulations are relevant to human language.
Our research deals with the following key issues:
- Speech synthesis, i.e. the artificial production of speech such as that used in robots, reading devices for blind people, computer games or announcement systems.
- Prosody, and in particular aspects of timing and emphasis. How prominently are sounds produced at specific points of an utterance, and when? How is this perceived and modeled?
- Conversational prosody and gesture. In this research area, we are interested in various aspects of multimodal communication, such as the synchronization of sounds with facial expressions and gestures, the phonetic realisation of disfluent speech and its integration in systems of human-machine interaction.
