Let your kids use your computer. This is a blank green screen. Let them play with the keyboard. They see and hear the letter sounds they press. If they press space after a word, it prounounces the word correctly rather than phonetically.
    
     They can use backspace and change letters to get it to sound exactly right, and try to make the computer talk to them.
