Won’t the use of picture / augmentative and alternative communication (AAC) interfere with a child’s vocal development?

Research shows that AAC does not impede the development of speech and language skills.  It actually indicates that AAC facilitates spoken language by increasing interaction, improving language skills, and/or providing a voice output model for speech.  Additionally, research shows that children who are not able to communicate effectively by some means are at great risk for cognitive, social, emotional, and behavioral problems.  The purpose of AAC is to provide a functional communication system, which may be used short or long term.
