Hi -
Conceptually this isn't hard at all. Here's how it could work:
1. Create a callback list for the movie. (Look up "callbacks" in the
docs. "The callbacks" is a player property.) A callback list is a
set of lines where each line contains two items: a movie time
reference and the name of the handler to be called at that time.
2. Organize your text so each "read segment" is on a line by itself.
3. Create a handler to be called by the callbacks, that uses the
"revSpeak" command to read the next line of a set of text lines.
Here's some "prototype" code (not tested, probably over-simplified):
The "callbacks" player property:
500,"readNextLine"
1155,"readNextLine"
2306,"readNextLine"
I'm assuming the text to be read is brought into a local variable before
the movie starts. Because of that, all the following code should be in
the same script:
-- start of code ------------
local vMovieText
on playStarted
put the uMovieText of this stack into vMovieText
revLoadSpeech
end playStarted
on readNextLine
revSpeak line 1 of vMovieText
wait until revIsSpeaking() = false with messages
delete line 1 of vMovieText
end readNextLine
on playStopped
revUnloadSpeech
end playStopped
-- end of code -------------
I think that's about all you would need if you do it this way, and there
are no doubt other ways. At any rate it gives you a starting point.

I need to have a text file read using the system's text to speech engine
and have it synched to a video. No talking heads just description of the
activity in the video but there would be periods where no speech is
required, in other words, intermitent speech timed to the video. Along the
lines of the old text tracks in QuickTime but what I want is speech
tracks. Does such a thing exist? Anyone have any ideas on how I might go
about accomplishing this? To complicate things it needs to run on
Windows, and OSX. Linux would be nice but not critical.
