Augmentative and Alternative Communication (AAC):

Augmentative and alternative communication (AAC) is a compensatory strategy to help people with speech/language deficits find successful ways to communicate, learn, and work besides talking. An AAC system includes tools/devices to help in communication, which may grow unnecessary as speech improves. Others use ACC throughout life, like many with autism.

• Augmentative communication methods supplement or enhance existing abilities to speak, often involving picture boards, sign language, or electronic devices to express thoughts and needs. This =helps with speech impairment, developmental disability, neurological disorder.
• Alternative communication methods replace speech (sign language, facial expressions, gestures). Early use helps lessen frustration when trying to communicate, develop language skills and vocabulary. No- and low-tech options: writing/drawing, spelling words by pointing to letters, or pointing to photos. High-tech options: apps or speech-generating device.
