The nature and function of vocalizations in atypical communication
Purpose of Review A survey of current research including people with disorders in which speech is impaired shows that
vocalizations are vastly discussed as a communication strategy, used both in isolation or paired with other aids. The principal
goal of this paper is to describe the ways researchers are using the term vocalizations and the meanings and functions attributed to
it. We also discuss possible future developments for specific research on unaided communication.
