Recent investigations of non-human primate communication revealed vocal behaviors far more complex than previously appreciated. Understanding the neural basis of these communicative behaviors is important as it has the potential to reveal the basic underpinnings of the still more complex human speech. The latest work revealed vocalization-sensitive regions both within and beyond the traditional boundaries of the central auditory system. The importance and mechanisms of multi-sensory face-voice integration in vocal communication are also increasingly apparent. Finally, studies on the mechanisms of vocal production demonstrated auditory-motor interactions that may allow for self-monitoring and vocal control. We review the current work in these areas of primate communication research.
