"Teachers With Apps http://teacherswithapps.com/ ; brings you 31 super speech and language iPad apps for home, classroom, and/or the therapist’s office. Speech and language is one area of educational apps that has exploded with smashing success. The prices range anywhere from free to expensive–there is a stuttering app that runs almost $1,000! Don’t fret, most are reasonable and many have a free/lite version."
