Frequently linked to sophisticated speech communication devices resembling laptop computers, augmentative and alternative communication (AAC) encompasses a spectrum of tools and strategies ranging from pointing, writing, gestures, and facial expressions to sign language, manual alphabet boards, picture symbols, and photographs used to convey messages in the absence of intelligible speech. While AAC systems incorporating voice-output devices may be perceived as more efficient than those without advanced technologies, multi-modal systems often work best when the ability to speak is compromised or lost due to the effects of stroke, amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease), and traumatic brain injury, among other acquired conditions. This article provides information about finding the right AAC device and discusses the process of implementing an AAC system.
