Vocal Charades: The Emergence of Conventions in Vocal Communication

Evidence suggests that signed languages emerge from communication through spontaneously created, motivated gestures. Yet it is often argued that the vocal modality does not afford this same opportunity, and thus it is reasoned that language must have evolved from manual gestures. This paper presents findings from an iterative vocal charades game that shows that under some circumstances, nonverbal vocalizations can be sufficiently motivated to ground the emergence of spoken conventions.
