We know that making your own pages is an important feature for AAC. But the vocabulary isn’t designed to develop more general communication skills outside of that particular context. These pages help users during a specific activity, like meal time or a science lesson. In earlier systems, most subject-specific AAC pages consisted of highly specific vocabulary related to the particular activity – a few sentence starters, a handful of nouns, and a few verbs and adjectives.

Keeping frequently used words in consistent places also takes advantage of one of the ways we learn how to do things - motor planning.
It helps the user quickly locate the words he or she wants to use, no matter where they are. For this reason, keeping words in consistent locations on all pages of an AAC vocabulary is very important. To communicate and effectively, AAC users need be able to easily access and recognize core words. So how does someone decide how to organize words? How can they make it easiest and quickest for a user to find and use words using AAC? We also know that time is precious for educational professionals and parents – how can they customize a system for an AAC user with as little work as possible? Consistency is keyįinding and recognizing words from a list can be hard enough if you already know a language – imagine how much more difficult it can be for an AAC user, still building their language and communication skills. Quick access to core words is a powerful tool for efficient communication, and Proloquo2Go is already loaded with the vocabulary that will most likely be used. In English, for example, 50 words account for 40-50% of what we say, 100 words account for 60%, and 200-400 words account for 80% of all words used in typical conversation across all ages. This small set of words dominates everyday speech for people of all ages and abilities. Luckily, our system already has a huge advantage by providing research-based core words. It needs to contain the right words so the user can say whatever they want, but it also needs to be small and manageable, with categorization that helps a user find words quickly. A symbol-based Augmented and Alternative Communication (AAC) user, on the other hand, needs to have words physically in front of them to be able to use them.Īs you can imagine, this presents a unique challenge for an AAC vocabulary. One thing you probably take for granted about spoken and written language is that you can very easily store words in your memory, without having to carry a dictionary around with you constantly.
