| Abstract | Models for speech motor control rarely have any intrasegmental temporal domain, but such a domain is necessary for certain classes of speech sounds. Discussed is one such instance in the production of Swedish stops. Voiceless obstruent production requires precise temporal control & coordination of several articulatory systems. Examined is the coordination of laryngeal & oral articulations in stop production using the transillumination technique & aerodynamic records. The main difference between aspirated & unaspirated stops is one of interarticulator timing; timing also appears to be the way in which the articulatory system solves the problem of controlling glottal opening at release in aspirated stops. Results are discussed in relation to stop production in general. Some basic characteristics of laryngeal articulatory gestures & implications for theories of speech motor control are outlined. |
