ON GESTURES TIMING IN EUROPEAN PORTUGUESE NASALS
Catarina Oliveira, Universidade de Aveiro António Teixeira, Dep. Electrónica Telec & Informática/IEETA, Universidade de Aveiro Paper File |
| In this paper a first study of gestures timing in European Portuguese nasals is presented. Velum, lips and tongue tip gestures were automaticaly annotated in an existent EMMA corpus. Analyses concentrated in the characterization of the different gesture landmarks in terms of average duration values, investigation of factors influencing such durations, and characterization of inter-gestural coordination. | |

| Comparatively little is known about the role that the velocity profiles of different articulatory movements play in speech production. Using 3D Electromagnetic Articulography, the present experiment analyzes articulatory data from Moroccan Arabic for independent influences of oral articulator and manner on stiffness, which is an important aspect of the velocity profile of articulator movement. Tongue back movements were found to have lower stiffness than those of the tongue tip or lower lip. No differences based on manner were found. Relevance to phonetics and phonology is discussed. | |

SERIAL-ORDER CONTROL AND GROUPING IN SPEECH: FINDINGS FOR A FRAME/CONTENT THEORY
Victor J. Boucher, Université de Montréal Paper File |
| Frame/content (F/C) theory [1] offers a working rationale of the rise of serial-order control and forms without assuming a priori units. A synthesis of our recent work is presented with the purpose of refining this rationale on two points. First, observations of contraction activity and passive elasticity suggest that basic frames of serial-order control correspond to contraction-relaxation cycles not present in non-speech motions such as mastication. Second, on explaining prosodic grouping, results show a relationship between “size effects” on such patterns and grouping effects on recall. Converging evidence suggests that grouping may arise from capacity limits on attention processes of short-term memory. | |
