Abstract: By what mechanisms is a given phone produced in various phonetic contexts? Electromyographic studies of articulator action have been made to provide data bearing on this question. An earlier study attempted to specify the relation between observed myographic activity and tongue movement when a subject produced vowels in a “neutral” ([p]-vowel-[p]) context. In this study of the same subject, the four vowel nuclei [i], [u], [æ], and [ɔ] were spoken with all possible combinations of the lingual consonants [t] and [k], in CVC monosyllables. Muscle potentials were recorded from 5 sites spaced evenly along the dorsal surface of the tongue and one ventral site near the tongue tip. In many cases during vowels, voltage levels either increased or decreased as compared with levels seen in the neutral context. Some of these changes suggested that muscles can produce (a) increase in tongue movement in the same direction as that required for the following phone, or (b) decrease in movement if the following phone requires a contrary movement. Other features of the motor control of coarticulation are also illustrated and discussed.
