"ChatterPix Kids is a free iPad app that you and your students can use to turn pictures into talking pictures. To create a talking picture just snap a picture with your iPad or import a picture from your iPad’s camera roll. After taking the picture just draw in a face and tap the record button to make your picture talk. Your recording can be up to thirty seconds in length. Before publishing your talking picture you can add fun stickers, text, and frames to your picture. Finished Chatter Pix projects are saved to your camera roll and from there you can export it to a number of services including YouTube."
