Yes, the program is suitable for children with speech difficulties.
The skills targeted by ReadingSounds 1 Pro are skills that have been found to be important for all children learning to read. There is emerging evidence linking literacy difficulties to speech, language and auditory processing difficulties. These children are more likely to experience phonological processing issues and thus are more likely to experience difficulty in cracking the code of written language.
