Investigates the various connections between the earliest human sounds and subsequent language development. With special attention to tracheostomies, Down syndrome, deafness, and speech-motor impairments, the authors examine the interaction between speech and language in typical development and the effect that that interaction has on language disorders. The 11 chapters provide linguists, psychologists, and speech-language pathologists with theoretical and clinical applications for connecting speech and language in their work.
