Here's what some of our users has to say: “I work with a range of ages, from Early Intervention through developmentally challenged students in high school. And I must say, it has become one of my ‘go to’ tools for many of the children in my practice. I highly recommend it.” - Cynthia James, M.A. CCC-SLP, Midland Park, NJ “I was able to pick up the app and instantly use it to drill my little girl on all three /k/ sets. SpeechBox worked beautifully and exactly as intended. She enjoyed the pictures and interface. It is the only speech therapy app I have found to be that useful with my daughter. Best speech therapy app I've laid hands on so far.” - Dala, M.A., CCC-SLP (Testy yet trying Blogger, Author) “Students with Apraxia require such repetitive practice in order to learn the motor movements for speech, making it very important to select words that kids will practically use throughout their day. SpeechBox has done just that. With beautiful pictures and a very thoughtful approach to selecting target words, SpeechBox is able to go beyond your typical articulation app in meeting the needs of children with diverse speech challenges.” - Katherine Kelley, M.A., CCC-SLP (Peachyspeech.com Blogger) ••SpeechBox for iOS was voted Best App Ever, Special Needs Category for 2012-2013, and Runner-up 2013-2014•• Questions?
