![]() TC is an app with dedicated version of the software on the NovaChat Semantic Compaction (different word sequencesįringe vocabulary is organized by category into folders. AAC Devices & Apps: Overview of Platforms, Languages, & Language Systems (as of ) The table below provides a basic overview of language system and vocabulary organization. One way to think of them is to divide them into categories. You could think of this as a more fine-tuned process of feature matching the settings that give the user what they need.Įven so, there are some major differences between types of apps. In a sense, we may not have to work as hard at “feature matching” between apps. This allows us to customize within an app to meet a someone’s needs. Over time, companies have included more features and settings. When these apps first came out, there were more differences between them. Robust apps give the user access to core vocabulary, secondary folders of context-specific words, navigation between screens, and a way to use distance communication (send emails, texts, and post to social media). Many of the apps for augmentative communication have similar features. ![]() Features to be compared may include screen size, language systems, mounting options, selection method (direct touch, eye gaze, head tracking, switch-scanning, etc.). In some cases, we may be comparing the features of different apps or devices. This happens when we match the abilities and needs of the communicator to the right tool. An earlier training introduced the concept of features matching. It really depends on the needs of the individual. There is no hierarchy that says high tech is better. The tools used to support communication range from light tech, paper-based systems up to high tech computer-based AAC that is state of the art. That is why there are two AAs in the acronym! When someone cannot speak at all, we use AAC as an alternative form of communication. We augment, or help, someone’s existing communication. ![]() When someone can speak but needs help to be understood (or can’t speak in every situation), we call this augmentative communication. When we rely on our bodies, this is unaided AAC. When we use tools to support communication, we call this aided AAC. These forms of communication can be divided into those that don’t require any tools (Facial expressions, body language, gestures, and signs), and those that use tools (from light tech to high tech). They are the professional organization that governs the work of speech pathologists and audiologists.ĪAC “includes all forms of communication (other than oral speech) that are used to express thoughts, needs, wants, and ideas” ( ASHA, 1997 ). Here is the official definition from the American Speech-Language and Hearing Association (ASHA). AAC includes anything other than oral speech that is used for communication. AAC stands for augmentative and alternative communication.
