The Importance of Sound Walls in Reading

The phonemes the sounds are usually represented by pictures of a mouth. There is no research that I know of right now and there may be some being done in fact I think there is but there's no published research about the use of sound walls. This is more of a tool for students and for teachers to use that does have research behind it. But we can say that it's a tool to teach the things we know are we are supposed to teach like phonemic awareness and phonics.
