Have some kids who are too shy to give their presentations? Want your students actually to want to practice their speeches? Then try out voki.com This animation site will record your voice and then you can pick your avatar and even disguise your voice. You can even use your cell phone for the audio, upload an audio file done in audacity or other audio editor or type it and it will take text and turn it into speech. It's fun. Then --without a log on--you can post a link or embed your voki in Moodle or a website or blog, like I have here.
