Augmentative and Alternative Communications (AAC) for Verbally Challenged People with IDD
By Randy Kiser, Community Living, Inc., Senior Business Development Manager
Augmentative and Alternative Communication (AAC) provides people with or without an IDD, who are non-verbal or minimally verbal, with reliable ways to express themselves and connect with others. Low-tech AAC systems, including communication boards, picture books, core-word boards, and yes/no cards, remain essential because they are accessible in any setting, require no connectivity, and allow quick communication when needed most.
High-tech AAC options, such as speech-generating devices and communication apps, expand opportunities through customizable layouts and robust vocabulary systems. Many modern tools include artificial intelligence (AI) supported features that help improve communication efficiency. For example, the Voiceitt (www.voiceitt.com) app uses AI-based speech recognition designed to understand atypical or non-standard speech patterns, allowing people whose speech may not be easily understood by others to communicate more independently. Features such as symbol prediction, adaptive interfaces, and personalized vocabulary support can increase speed and accuracy, but they enhance, rather than replace, human interaction, modeling, and support.
Successful AAC use depends on consistency and strong communication partners. Families, staff, and peers should model language on the AAC system during everyday activities to demonstrate real-world use. AAC is not a reward or a toy; it represents the person’s voice and should always be respected and readily available.
Access to AAC should extend across all environments, including home, school, work, and community settings. Regular opportunities to use AAC build confidence, competence, and communication fluency. Thoughtful integration of AI features can further support natural, responsive communication experiences and help develop meaningful relationships.
