Topic-060: Overlapping Gestures

Speech sounds are produced with the movements of the articulators and sounds are often described in terms of their articulatory gestures. Remember that sounds are not static they are movements. This idea makes it easier to understand the overlapping of sounds in terms of their articulatory gestures. Try saying words twice, dwindle, quick and analyze the rounding of your lips for sound w. In each of these three words, the first stop sounds are slightly rounded (when they are clustered with w - /tw/, /dw/ and kw respectively. In these words, there is a tendency for gestures to overlap with those for adjacent sounds (stops with bilabial win this case. This kind of gestural overlapping, in which a second gesture starts during the first gesture, is sometimes also called anticipatory co-articulation. The articulatory gesture for the approximant sound is anticipated during the articulatory gesture for the stop. The same kind of anticipatory overlapping takes place in words like tree and dream (compare them with tea and deem). In phonology, overlapping refers to the possibility when a phone maybe assigned to more than one phoneme (phonemic overlapping. As a notion, overlapping was introduced by American structural linguists in the s.
