We also read about several developmental frameworks that offered broader ways to think about AAC interventions. She argues that by applying principles of typical development to the use of AAC techniques and devices, we may better facilitate the development of communication systems that are flexible and responsive to the child's communication needs. Specific challenges of using and learning language with AAC call for unique solutions. At the same time, as a part of language intervention, it is important to facilitate a child's ability to vocalize and produce natural speech. Early on we cannot predict if and when intelligible speech will emerge.
Vocalizations continue to be important communication signals throughout life.
Current research on early language acquisition often reflects values and beliefs of white, English speaking, American families. Not all groups feel the same about the value of talking, how social interactions should proceed, and how to teach language to young children. Children who do not talk well receive less input than other children in the same environment. Children with caregivers who use a more responsive interaction style progress more quickly, but interactions with AAC tend to be more adult directed. Follow a child's lead and attend to the child's preferences.
