| Abstract | This paper summarizes the results of several experiments that used the techniques of cinefluorography and electromyography to study the organization of speech gestures. As such, it does not represent a comprehensive review of current speech production theory, but rather is directed towards a discussion of several specific issues that are best studied by these techniques: the dynamics of articulatory movements and the motor command structure that underlies those movements. Although speech is usually described in terms of a string of invariant segmental units (phonemes), the act of speaking imposes on this string a complex encoding. This is a consequence of the series of events that comprises the speech production chain: the conversions of motor command-to-muscle contraction, muscle contraction-to-vowel tract shape, and vocal tract shape-to-acoustic signal. The result of this encoding is observed as variation both in the production of a given phone and in its acoustic representation. This paper will be concerned with allophonic variation as it appears at the articulatory level, specifically, variations which arise from changes in phonetic context, and variations which arise from changes in the suprasegmental structure of the string, particularly changes in speech rate. |
