It is one of the fundamental problems in the study of speech to determine the vocal tract area functions and to investigate how they move during articulation. It is also important from the applicational points of view such as speech synthesis or recognition. The model constructed for the transitions of the vocal tract area functions among vowels have been applied to unvoiced and voiced stop consonants, by taking account of the characteristic manner of articulation of stop consonants. First we have assumed the two target configurations for each consonant, the one followed by the back vowel and the other followed by the front vowel, which have negative sections. The same target configuration has been used for both voiced and unvoiced stops. The transitions for consonant-vowel and vowel-consonant-vowel have been carried out, and the patterns of the first three formant frequencies obtained by the rules are coincident with the observed ones. For the context of VCV, we have also examined the relation between the duration of consonant and the 2nd formant frequencies of the vowels, and have been able to explain by our rules the effect of the rapidity of pronunciation upon the onset of the 2nd formant frequency of the following vowel.
