Abstract :
A model of the final stages of speech production, implemented on a VAX 11/780 computer, is described. Flexibility and a capacity for development in line with published data on real speech are achieved by means of a large number of parameters. The model is used to investigate the extent to which observed patterning of selected speech sounds is predictable from production processes and constraints. For sequences containing ´open´ or ´close´ vowels combined with voiced or voiceless fricatives, the simulation yields the kind of covariation of consonant and vowel segment features that is observed in real speech.
