Children with developmental dyslexia confuse letters and syllables when they read.
"...they can't analyze fast-changing sounds, their sound map may become confused. "Children with developmental dyslexia may be living in a world with in-between sounds," says Gaab. "It could be that whenever I tell a dyslexic child 'ga,' they hear a mix of 'ga,' 'ka,' 'ba,' and 'wa'. "Reading trouble may develop when these children first see printed letters, Gaab and cognitive scientists believe, because at this stage, the children's brains wire their internal sound map to letters they see on the page. Linking normal letters to confused sounds may lead to syllable-confused reading. But the brains of the children with dyslexia changed after completing exercises in a computer program known as Fast ForWord Language.
