AAC Dictionary for Functional Communication skills as well as Literacy Skills

I have begun to look at the impact that wishing to extend the symbol dictionary to one that will also enhance literacy skills may have on the project design. The first presentation I came across has provided some guidelines for those supporting English AAC users and is backed by research funded in USA – AAC-RERC is a Rehabilitation Engineering Research Center that functions as a collaborative research group dedicated to the development of effective AAC technology.   I wanted to see where text to speech (speech synthesis) could help and see how the need to include not just the alphabet with sound support, but also letter combinations, blending and segmentation that help with reading and spelling might also need to be in place, bearing in mind this is not necessarily the case in Arabic. That will be the next stage of the research.

There is a presentation provided by Professor Janice Light (Penn State University) describing the components of effective literacy interventions for individuals who require AAC called “Maximizing the Literacy Skills of Individuals who Require AAC”

I have taken the main elements and added the image of a set of books to each section that would have an impact on the symbol dictionary.  The text version of the mindmap  can also be downloaded.

There is the importance of being able to link the words learnt in the reading exercise  to  symbols available in the dictionary to enable AAC users to show they have understood or remembered the word. This means that there will need to be a way of adding symbols and words at anytime with guidance for image creation and categorisation.

As mentioned offering phoneme segmentation and ways of showing an understanding of sound blending is important.  Speech output whether this is human or a good quality synthetic computer generated voice should be available to encourage, reinforce and enhance literacy skills.

The information for this blog came from a “literacy program developed and evaluated by Dr. Janice Light and Dr. David McNaughton through a research grant (#H133E030018) funded by the National Institute on Disability and Rehabilitation Research (NIDRR) as part of the AAC-RERC.”  I will be adding the academic papers related to this subject to our Useful Articles page but here are some that were included at the end of the AAC-RERC slides.
