Dyslexia is a specific learning disability that affects about 7% of the population and in particular 200 000 children
between ages 6 and 11 in France.
Children with specific language impairment (SLI) have difficulties in several aspects of language, including phonology,
morphology and syntax, despite normal intelligence, adequate hearing, normal learning opportunities and the absence
of any neurological or psychiatric trouble.
RapDys are gamelike exercises based on carefully chosen and tested voicing continua. They can be done under the
supervision of a speech and language therapist and further on at home.
