I'm trying to confirm a vague recollection about the text-to-speech PlainTalk / MacinTalk software shipped with Macintosh computers. If my memory is right, this would have been around 1994, and based on the Wikipedia description I think it would have been MacinTalk Pro on a Quadra-series machine. I remember the "funny" voices like Cellos, Zarvox, etc.
I recall that the text-to-speech would occasionally and unexpectedly speak the words "open-apple hold" when reading. I never knew why or what triggered it. It may have happened when attempting to read garbage text or something else that wasn't really words.
Does anyone remember this behavior and know why it happened? A recording of it would also be interesting, if you have an appropriate machine and can reproduce it.
It's possible that I misheard and that "hold" was really some other word, but I am pretty sure about "open-apple", which was presumably a reference to the open-apple / command key on the keyboard. It's also possible that I am mixing this up with an even earlier version of MacinTalk.
