This paper attempts to validate Stevens' quantal theory of vowel articulation by studying the acoustic effects of a wider and considerably more realistic and natural range of articulations than the simple tube model used by Stevens. Our model is implemented on a Macintosh computer and uses a vocal tract shape that is fairly similar to that of a human speaker. We studied the acoustic effects of a large number of articulatory vowel gestures. The results do not show much support for a quantal theory of vowel production. When articulatory gestures are varied in a simple way, the acoustic effects tend to vary monotonically with the articulatory variation, thus not producing stable plateau areas in the formant patterns.
