Practice Report

To share a case study about a 19 year old non-verbal female student's progression from no reliable communication system to a low-tech wordbook and then a high-tech voice output communication aid.


Initially, AAC assessment within a multi disciplinary team. Individual weekly sessions for three academic years, devoping and recognising the need for independent communication in everyday life. Introducing a low-tech wordbook with vocabulary that was similar to a program available on a high-tech device. Pace was dictated by the student and her motivation to move from a low- to high-tech method.


Once she had a high-tech device, she was able to use it functionally very quickly. She was enthusiastic and accepting of high-tech communication at this point and was being very assertive in her use of voice output to communicate in new ways such as making phone calls.


Increased ability to transfer skills and knowledge gained from wordbook to high-tech device. The speed of immediate functional communication was increased through familiarity of vocabulary and layout. The extended time to allow the student to work at her own pace led to sustained and increased motivation to communicate.
