- The influence of the palate shape on articulatory token-to-token variability (2005)
- Articulatory token-to-token variability not only depends on linguistic aspects like the phoneme inventory of a given language but also on speaker specific morphological and motor constraints. As has been noted previously (Perkell (1997), Mooshammer et al. (2004)) , speakers with coronally high ”domeshaped” palates exhibit more articulatory variability than speakers with coronally low ”flat” palates. One explanation for that is based on perception oriented control by the speaker. The influence of articulatory variation on the cross sectional area and consequently on the acoustics should be greater for flat palates than for domeshaped ones. This should force speakers with flat palates to place their tongue very precisely whereas speakers with domeshaped palates might tolerate a greater variability. A second explanation could be a greater amount of lateral linguo-palatal contact for flat palates holding the tongue in position. In this study both hypotheses were tested.
- Supralaryngeal mechanisms of the voicing contrast in velars (2005)
- This study investigates supralaryngeal mechanisms of the two way voicing contrast among German velar stops and the three way contrast among Korean velar stops, both in intervocalic position. Articulatory data won via electromagnetic articulography of three Korean speakers and acoustic recordings of three Korean and three German speakers are analysed. It was found that in both languages the voicing contrast is created by more than one mechanism. However, one can say that for Korean velar stops in intervocalic position stop closure duration is the most important parameter. For German it is closure voicing. The results support the phonological description proposed by Kohler (1984).
