| Abstract | Electromyographic recordings of the levator palatini were obtained to investigate the relationship between velar movement and it motor command. Two Japanese subjects read a list of meaningful disyllabic test words. There was no systematic difference in EMG level between either voiced and voiceless or stop and fricative consonants. Rather, the activity level for a given nonnasal consonant varies with its phonetic environment. Electromyographically, anticipatory nasal coarticulation generally followed the so-called look-ahead mechanism, although in some examples there seemed to be a restriction of the anticipatory effect. On the other hand, carry-over nasal coarticulation was not as pervasive as the anticipatory effect, as the carry-over effect was present for vowel segments following syllable-initial nasals, while it was absent for vowel segments following syllable-final nasals. |
