Remarkably little is known about the acoustic phonetics of infant vocalizations that can be specifically regarded as precursors to speech. It is nonetheless clear that, prior to babbling, infants use a variety of vocalizations, dubbed 'protophones,' with varying degrees of phonatory control. It is also clear that phonatory control involves selection among the distinct vibratory regimes known to occur in highly non-linear systems like phonation. Furthermore, it appears that phonatory control plays a major role in the development of primitive capabilities to communicate emotional states vocally and to direct vocalizations toward caretakers. The present investigators have embarked upon a program of research designed to evaluate the role of phonatory control in infant vocal development. This paper provides a progress report on that effort.
