You can Build a Bear at Build-A-Bearville, make it say what you want it to say, and then email the url to be posted on a website.

Students will have fun with the “Dress Me,” “Fluff Me,” and “Stuff Me” features.  English Language Learners can write something and have the bear say it with the text-to-voice section.

I’ve placed the link on my Examples of Student Work page under Student Bears.
