What We Do:


  • 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.



  • We have 2 papers accepted at this year’s Interspeech conference in Brno: "Effects of time pressure and spontaneity on phonotactic innovations in German" (Petra Wagner, Sina Zarrieß, Joana Cholin); "Cue interaction in the perception of prosodic prominence: the role of voice quality" (Bogdan Ludusan, Petra Wagner, Marcin Wlodarczak)

  • We proudly announce that the DFG funds the TRR318 on "Constructing Explainability", with 2 of its subprojects being partially located in our workgroup: project A02 on "Monitoring the understanding of explanations" (in collaboration with Angela Grimminger, Uni Paderborn, and Hendrik Buschmeier, Uni Bielefeld); project C06 on "Technically enabled explaining of speaker traits", in collaboration with Reinhold Häb-Umbach (Uni Paderborn).

  • Jana Voße has presented her Poster titled "Pragmatic and Acoustic-Phonetic Aspects of Motivating Speech" at PaPe 2021

  • 2 papers from our work group "Hesitations Distribution in Italian Discourse" by Loredana Schettino, Simon Betz and Petra Wagner as well as "A Crosslinguistic Study on the Interplay of Fillers and Silences" by Simon Betz, Nataliya Bryhadyr, Loulou Kosmala and Loredana Schettino were accepted for DiSS Workshop 2021 in Paris

  • The DFG funds our new collaborative project with Reinhold Häb-Umbach’s group from Paderborn on "Deep speech representation learning for research in phonetics"

  • The DFG funds our new project on "Laughter in conversation: form, function, and multimodality"

The Phonetics and Phonology research group is part of the Center for Cognitive Interaction Technology CITEC and Bielefeld University's Faculty of Linguistics and Literary Studies.
