A colleague showed me this site and it is awesome. You just paste in some text to the site and it will change the text to a sound file in MP3 form.
You can change your text to a male or female voice (Mike or Crystal).
I see a variety of educational uses for this. Specifically for me, I can use MP3 sounds in SMARTBoard software.
I can't wait to make a lesson involving sounds with my Smartboard.
