There's no substitute for a fabulous teacher, but sometimes technology can be a welcome supplement to what kids are learning at school. When your child's receiving extra help for speech, repetition is the name of the game, and that's where a handful of apps come in to play. While your own speech-language pathologist will work with your tot to correct speech issues, these apps are here to encourage practice between sessions. They're costly — free versions often only include a handful of sounds; the more complex letters and sounds are included in full and pro versions — but they're designed and used by therapists, so you know they're good. Check out a few of our favorite speech apps of all time.
