Figure 2.

Metaphorical illustration of the concept of gestural parsing. Panel A shows the acoustic consequences of two gestures that overlap in time, captured in a space in which the x-axis is time and the y-axis reflects the relative prominence of the gestures’ acoustic consequences. As panel A illustrates, during the time in which the two gestures overlap (the gray region in the figure), the acoustic consequences for the two gestures are inextricably mixed. In panel B, the mixing of the acoustic consequences of the two gestures is eliminated by situating the acoustic signal in a space that captures the signal’s gestural causes.
