I think this is it. Thank you so much.

Hi all,
I am trying to write an app that has a hard-coded NSString, formatted
like this:
@"Alex: This is a test.\nBruce: One two.\nFred: This is another test."
The idea is that the lines in the text are spoken using the indicated
voice. In the example above, line one is Alex, line two is Bruce, and
line three is Fred.
I'm puzzled, however, because what ends up happening is that only the
last line ("This is another test") is spoken. Furthermore, the voice
used is the first one in the list (Alex). I've tested this with
multiple last lines and voices.
So, I set breakpoints in my code:
(IBAction)speakPlay:(id)sender
{
NSLog(@"Starting to speak play");
[isSpeakingField setStringValue:@"Speaking"];
for (NSString *line in separatedPlay) {
// set the speaker for this line
NSUInteger locationOfFirstColonInLine = [line
rangeOfString:@":"].location;
NSString *characterForLine = [line
substringToIndex:locationOfFirstColonInLine];
[speechSynthesizer setVoice:
[NSString
stringWithFormat:@"com.apple.speech.synthesis.voice.%@",
characterForLine]];
NSString *partOfLineToSpeak = [line
substringFromIndex:(locationOfFirstColonInLine + 2)];
// speak the part of the line after the character
[speechSynthesizer startSpeakingString:partOfLineToSpeak];
}
}
does the speech synthesizer 'queue up' requests like that? Seems more
likely that you're ripping through your for loop setting the voice and
the line to speak 3 times, each one just overriding the one before so
you just get the last line. I would think you need to wait for a
delegate callback telling you one line is finished before enqueing the
next
