While all students must learn to read fluently, high-end text-to-speech software can help students with learning differences develop these skills by enabling them to read along with the voice-over. As students are developing their reading fluency skills, adults will want to continue to develop a student's writing skills. When students hear their work read aloud, they can find mistakes that they might not realize by reading alone. For some students, software might be a good substitute if they are uncertain about their own reading skills.
