Current Research:
Open-Mouthed or Stiff Upper Lip? Exploring Language-Specific Articulatory Settings in English-German Bilinguals (ESRC / RES-000-22-3032)

There is growing evidence that languages differ in the way speakers of a language set up their articulators, e.g. their tongue, their lip and their jaw - in speech, and in the preparation for speech. This phenomenon is often referred to as language-specific articulatory settings.

We are testing German-English bilinguals to explore whether bilingual speakers keep their two languages apart by using their articulators in a different manner for each language. To this end, we are gathering acoustic as well as articulatory data - the latter employing Ultrasound Tongue Imaging (to determine the overall shape of the tongue), the motion-capture system Vicon (to determine the position and movement of the jaw and the lips) and Electropalatography (to determine contact patterns of the tongue with the roof of the mouth).
