Which of the following best describes an Alternative Communication System?

An Alternative Communication System is defined as any means of communication that deviates from conventional natural language systems. This encompasses a wide range of methods beyond just spoken or written language, incorporating tools and techniques such as symbols, pictures, sign language, and technology-assisted communication devices. Such systems are particularly useful for individuals who may have difficulties with traditional communication forms due to disabilities or language barriers, allowing for a more individualized approach to communication.

The other options describe more restrictive forms of communication. For instance, focusing solely on speech or written language does not capture the broader spectrum of methods available within alternative communication systems. Additionally, limiting communication exclusively to sign language ignores the variety of other approaches that individuals may use based on their unique needs and situations. Therefore, the correct answer accurately reflects the inclusive nature of alternative communication methods, supporting diverse communication needs.
