This is a cute app and it was fun to have my child read the words and practice her articulation. The therapist's voice is clear and easy to hear and mimic. I also liked the ba- ba ba ba- ba ba ba jingle as it got my child to repeat and match the sound= good mouth exercise. @Developer- please note that the link at the end to Preferred Apps goes to the iTunes store and NOT to the APPstore. That made it a chore to find your other apps. I wish this app had MORE letter sounds.
