TOPIC:	Levels of analysis of tongue motion
ABSTRACT:	Most consonants and all vowels of the world's language require a distinctive configuration of the tongue. This articulator is therefore crucial in most of the contrasts that shape segmental inventories. The ability of the tongue to assume a large number of shapes and to rapidly change from one shape to another is crucial to the success of speech as a communicative device. I will argue in this presentation that to understand the coarticulatory behavior of the tongue one must understand how the biological complexity of this organ is utilized in its linguistic functioning. To do so, we must distinguish three levels of study of tongue movement: area, function change, tongue constriction evolution, and individual fleshpoint movement. Data on tongue movement at each level will be provided, and the hierarchical relation of the levels will be discussed. m
