A key feature of augmentative and alternative communication (AAC) systems is that they help individuals with speech and language impairments communicate effectively. AAC systems are designed to enhance or supplement the communication abilities of people who have difficulty speaking or writing due to various conditions, such as autism, cerebral palsy, or stroke. These systems can include a range of low-tech and high-tech options, such as picture communication boards, speech-generating devices, and mobile apps, to facilitate effective expression of thoughts, needs, and preferences.

Using AAC systems enables individuals to engage in more meaningful interactions, improving their social, academic, and professional opportunities. It also promotes independence by providing alternative methods for expressing ideas when traditional speech is not available or reliable. This focus on enhancing communication skills makes the identified answer a comprehensive reflection of the purpose of AAC systems.

In contrast, while writing skills may be supported by some AAC interventions, they are not the primary focus of these systems. Additionally, limiting AAC to only individuals who are deaf overlooks the broader range of individuals with speech and language challenges who benefit from AAC technologies. Lastly, stating that AAC consists solely of written materials ignores the diversity of communication modalities within AAC that includes symbols, gestures, and vocalizations.
