ANTICIPATORY COARTICULATION - SOME IMPLICATIONS FROM A STUDY OF LIP ROUNDING

The anticipation of articulatory features, in particular lip rounding in anticipation of a rounded vowel, has been reported to occur as many as four segments before the segment for which the feature is specified. In the date presented here, we find that the moter commands for the rounding gesture for /u/ begin a fixed time before the onset of the vowel. This timing is unaffected by the number of consonant segments in the preceding string. Thus, the initiation of lip rounding appears to be linked to other features of the vowel articulation. © 1979, American Association of Physics Teachers. All rights reserved.
