Create talking images with Blabberize.com.
Here’s a fun little site that came across my browsing this past week. Blabberize.com allows you to upload a photo, and then animate the mouth with audio you record or have recorded. Unfortunately, you have to create an account to save your work, which may be a problem for younger students. Once completed, you are given a link to share your work of art.
The site uses Flash, so it is living on borrowed time. Have fun with it while you can!
