To a large extent I work in close cooperation with colleagues from my lab, but also different laboratories in the world to share expertise in solving problems, making errors, and learn. I would never be - where I am now - without these cooperations. The list below is intended to show some (not all!) topics we have been working on in the last 5 years: 

  • Development of an open source tool (Matlab) for researchers to build their own speaker-specific biomechanical tongue models. The main part of this work was carried out by Ralf Winkler within the SPEECHart project, funded by the DFG. It is based on a 2D biomechanical tongue model developed by Pascal Perrier and Yohan Payan (GIPSA-lab, Grenoble). See: www.github.com/winkijeg/SPEECHart
  • My colleagues at ZAS: Marzena Zygis, Stefanie Jannedy, Jörg Dreyer (and  Melanie Weirich, our previous PhD student) are constantly giving me advice for phonological theories, prosody, statistics, sociophonetic background, and support with technical issues.
  • Building a motion capture lab at ZAS was one of the great opportunities we got, thanks to the funding of the BMBF. Together with Manuel Zellhöfer and Jörg Dreyer, we were able to run the first experiments using Optitrack, synchronize it with recordings of respiration and speech. This allowed us to investigate the effect of motion (so far rhythmical arm or leg motion) on breathing frequency and rhythmical structures of speech (with Amelie Rochet-Capellan (GIPSA-lab, Grenoble), Uwe D. Reichel (Academy of Sciences, Budapest), and my student assistant Olivia Maky.
  • I am interested in breathing as a biological rhythm, involved in speech production, perception and human interactions (dialogues) and share related ideas and work especially with Amelie Rochet-Capellan (GIPSA-lab, Grenoble).
  • I have been investigating several topics related to speech planning. In particular, whether inhalation depth and duration already reflect the length and complexity of the upcoming utterance (with Caterina Petrone (LPL Aix-en-Provence, Jelena Krivokapic (University of Michigan), Phil Hoole (LMU Munich), to what extent planning units are flexible and may be shaped by individual working memory capacities and speed of processing (with Caterina Petrone (LPL-Aix-en-Provence), Jelena Krivokapic (University of Michigan), Benjamin Swets (Grand Valley State University), acoustic parameters, like phrase initial f0 peaks and f0 declination that might be correlates of speech planning (with Amelie Rochet-Capellan (GIPSA-lab, Grenoble), Uwe D. Reichel (Academy of Sciences, Budapest)).
  • The coordination of articulators and their stability is a challenging topic to investigate. With Leonardo Lancia (LPL, Aix-en-Provence) and Amelie Rochet-Capellan (GIPSA-lab, Grenoble) we worked on the Labial-Coronal effect in French and German, two languages differing in their accentuation. Different prosodies might lead to different coordinative patterns between the jaw, the lips and tongue. To be able and analyse coordination with advanced methods (time series analyses), I rely especially on the expertise of Leonardo Lancia.
  • The relation between articulation and intraoral pressure is an underexplored area I am interested in. Since about 10 years I am collaborating particularly with Laura L. Koenig (Long Island University, NY & Haskins Labs, New Haven) on this topic. Recently, we run a study with EEG, intraoral pressure and respiratrace to investigate normal and loud speech and their effects on respiration, intraoral pressure and laryngeal configurations.
  • Together with Özlem Ünal-Logacev (Andalu university, Turkey) I work on applied research aspects. In particular, we use Electropalatography and intraoral pressure measures to provide reference values for selected Turkish sounds. Özlem will use these for clinical purposes, in particular to help people with cleft palate and velopharyngeal dysfunctions to improve their speech quality, and thereby life quality.
