Summary

During the first year of life, human infants undergo an extraordinary process of vocal learning, unmatched by other primates. This lays a key foundation for meaningful speech production. The first sections of this chapter describe major milestones and other features of the development of prelinguistic and early speech sounds, including the acquisition of new sound types and of conversational turn-taking skills. The chapter then discusses what we know about the roles of exploratory play, social input, and neural systems in human vocal learning. A section on computational modeling reviews theoretical work that informs our understanding of how these mechanisms interact. Effects of sociocultural and clinical differences on infant vocal development are then discussed. The final section of the chapter discusses policy perspectives on research and interventions in this domain.
