Augmentative and alternative communication, usually shortened to AAC, refers to communication methods and tools that support or replace speech when a person cannot rely on spoken language alone. AAC can include picture boards, text-based systems, speech-generating devices, eye-gaze tools, and other access methods.
How It Works
Some AAC tools supplement existing speech, while others act as the primary communication channel. Modern AAC increasingly overlaps with AI through prediction, personalization, better access methods, and smarter language support, but the core goal remains functional communication rather than technology for its own sake.
Why It Matters
AAC matters because communication support should not depend on natural speech alone. In therapy and rehabilitation contexts, AAC may exist alongside speech work rather than in opposition to it, helping the person communicate effectively while other skills are still developing or changing.
What Changed In 2026
AAC systems are increasingly part of a broader assistive ecosystem that can include AI-driven prediction, customization, and therapy support. That makes integration between speech tools and communication supports more important than before.
