Building Communication Skills Through AAC Technology

Communication is a fundamental human right. For non-verbal or minimally verbal children with autism, Augmentative and Alternative Communication (AAC) provides the tools and strategies needed to express needs, thoughts, and emotions effectively.

What Is AAC?

AAC includes any system — high-tech or low-tech — that supplements or replaces speech:

• Low-tech: Picture exchange systems (PECS), communication boards, sign language
• Mid-tech: Simple voice-output devices with recorded messages
• High-tech: Speech-generating devices (SGDs) and tablet-based apps like Proloquo2Go or TouchChat

AAC Does Not Hinder Speech Development

A common concern among parents is that introducing AAC might prevent their child from developing verbal speech. Research consistently shows the opposite — AAC supports and often promotes speech development by reducing communication frustration and providing a model for language.

Starting AAC

The process begins with a comprehensive communication assessment by a speech-language pathologist (SLP). The SLP evaluates the child's current communication abilities, receptive language, motor skills, and cognitive level to recommend the most appropriate AAC system.

At DACAC, our SLPs are trained in AAC assessment and implementation. We work closely with families to ensure AAC systems are used consistently across home, school, and community settings — because communication happens everywhere, not just in therapy sessions.
