Try the amazing Geedubya Speech Generator. I wish I could credit the original author but, I don’t know who it was. Click on the text or pic above to launch the speech generator. Or, you can [right-click > save as] and save it to your desktop and play with it at home. Drag the words down to the blank text area and click play.
