It is well known that the units of speech are not produced strictly sequentially but overlap with each other; this phenomenon has been referred to as coarticulation, coproduction, or blending. The present experiment examines one intra-articulator example of temporal overlap, namely the combination of successive opening and closing gestures in the larynx. Two subjects produced the utterance Kiss Ted at several different speaking rates with stress on the first or second word. Laryngeal abduction-adduction was monitored using transillumination and fiberoptic video recording. Results show that at slow rates two separate glottal openings occur associated with the fricative and the stop, respectively. At fast rates, a single smooth glottal opening movement is seen. At intermediate rates, partially overlapping gestures are found. These findings suggest that two underlying gestures are being blended into a single composite movement. Simulations suggest that the combination process may be some type of summation.
