When is AAC most appropriate?

• A. Severe receptive language difficulties
• B. Severe written expression difficulties
• C. Severe speech difficulties
• D. All of the above

Answer: (D)

AAC is appropriate whenever there is a significant barrier to communication across any domain—how someone understands others, how they express themselves, or how they convey written ideas. If understanding spoken language is severely limited, AAC can provide visual or symbolic supports to aid comprehension. If producing speech is severely impaired, AAC offers alternative means to communicate, such as symbol boards, sign systems, or voice-output devices. If writing is chronically difficult, AAC can facilitate message construction through prepared phrases, symbols, or electronic output. Because AAC can support multiple aspects of communication, it’s suitable in all of these scenarios, and many people use AAC across several areas at once.
