Which method assists individuals who cannot communicate effectively through speech or writing?

The method that assists individuals who cannot communicate effectively through speech or writing is augmentative and alternative communication (AAC). This approach encompasses a variety of strategies and tools designed to support effective communication for those who may have difficulty with verbal speech or written expression.

AAC can include both high-tech options, like speech-generating devices and apps, as well as low-tech options such as picture boards and communication books. The use of these methods allows individuals to express their needs, thoughts, and emotions, thereby improving their ability to interact with others and participate in daily activities.

The other options do not directly relate to methods of communication support for individuals with speech or writing difficulties. Deafness refers to a condition affecting hearing and does not provide a communication method. Dysarthria is a speech disorder resulting from muscle weakness affecting the ability to speak clearly, but it does not represent a communication method itself. Audition pertains to the sense of hearing and also does not offer communication solutions for those who struggle with speech or writing.
