Abstract
A simultaneous EPG/EMA study of tongue gestures of five speakers was conducted to investigate the kinematic events accompanying alveolar stop reductions in the context of a velar plosive /k/ and in the context of a laryngeal fricative /h/ in two languages, English and German. No systematic language differences could be detected. Alveolar productions before a following /h/ showed only a marginal weakening of the formation of complete occlusion, while alveolar productions before a following /k/ showed a wide range of reductions, including instances of a complete deletion of the alveolar gesture. The extension of movement reduction varied between and within subjects. Importantly, while speakers were consistent with themselves, they employed different articulatory patterns with respect to the timing relationship between movement initiation, overall movement duration, peak velocity as well as closure duration. An attempt is made to relate the observed movement patterns to the dynamic factors of the speech mechanism.
