In honor of the Mac's 10th birthday, Jon Kleiser <jon@hdo.hdata.no> worked up this set of embedded speech commands (with some bits modified intentionally to sound better - hence "Mackintosh") for Apple's Speech Manager. You must have the Speech Manager installed, and you need one of the many programs that can translate the text below into speech. I found Speaker 1.12 on my hard disk and it worked fine. You can find these on the nets as:
