Alternative communication refers to methods used to convey messages without relying on traditional speech. This can include tools and techniques such as sign language, picture exchange systems, and communication devices. These methods are especially beneficial for individuals with speech or language impairments, allowing them to express their thoughts and needs effectively. Many people use alternative communication to enhance their interactions. For instance, individuals with conditions like autism or aphasia may find these methods helpful. Additionally, technology has advanced the field, with apps and devices designed to support augmentative and alternative communication (AAC), making communication more accessible for everyone.
