Augmentative and Alternative Communication (AAC) refers to methods and tools that help individuals with communication challenges express themselves. This can include anything from simple picture boards to advanced speech-generating devices. AAC is especially beneficial for people with conditions like autism, cerebral palsy, or stroke, allowing them to share their thoughts and needs effectively. AAC can be categorized into two main types: augmentative communication, which supports existing speech, and alternative communication, which replaces speech entirely. By using AAC, individuals can improve their social interactions and enhance their quality of life, fostering greater independence and connection with others.
