Dr. D. Kimbrough Oller (Kim) is Professor of Communication Sciences and Disorders at the University of Memphis and Senior Fellow at the Konrad Lorenz Institute for Evolution and Cognition Research. A leading figure in the study of infant vocal development, Dr. Oller’s work introduced the concept of protophones—the spontaneous, speech-like sounds that precede words—and demonstrated their central role in both human development and the evolution of language. His research connects early vocal play, functional flexibility, and caregiver interaction as key foundations for communication. Unlimited
