Smart phone app for text-to-speech alien voice

Does anybody know of a smart phone app that voices text in an alien voice?

My workplace always has a costume contest on Halloween, so I’m going to put on a big green rubber alien head and borrow my friend’s sparkly robe. I’m going to have my Android phone do my speech for me, like it’s a Star Trek-type universal translator. All the text-to-voice apps I’ve found are too serious and politically correct, and don’t have anything silly. I’ll probably go with the old monotone robot voice if nothing else, but I’d like to find something cool.

There’s a bunch of free apps in the google store called “… voice changer …” They popped up by just searching for “voice”. I suggest downloading some and rying them out.

If you can’t find an app, try this website.

If the site works with your Android browser, Zarvox or Trinoids are probably your best bets for alien voices.
