This study performed by doctors at Children’s Hospital Boston evaluated how speech-part sounds, at various rates of change, affect brain activity in normal and dyslexic children.

In addition to revealing clues about the differences between normal and dyslexic children, the study also suggests that sound patterns trigger a rewiring of the brain in dyslexic children.  Repeated application of specific sound patterns gradually changed the dyslexic childrens’ brain patterns to match the normal group and improved reading performance.  The study didn’t evaluate the long term effects, but does reveal the power of sound patterns in the short run.
