if it is a self voicing app, it only needs the tts not voiceover.

Hi David,
You're only missing the context of the conversation. Bryan's been testing a
PC application that I've written to help VI musicians and I'm examining the
practicalities of porting it to the Mac and/or Iphone. This is a
self-voicing application, so the ability to tell VoiceOver to announce a
particular string is essential for such a project to fly.
Best wishes.

Bryan,
Since I was the one who told you that this situation has changed with OS4,
I've been unable to find the page where I read it - think I may be becoming
delusional with age, but I'll keep looking as it directly affects an
application I'm planning to develop.
Best wishes.

So, it doesn't support Daisy 2 or 3 standards, but
"Voice of DAISY cannot play a DAISY audio book that does not completely
conform to DAISY 2.02 standard."
That sounds confusing.
I think that the bottom line is that it only plays audio books. It doesn't
support TTS, so can't play anything other than audio.
The nonprogrammer types on the list might not be aware, but, unlike desktop
software on OS X or Windows, iPhone OS doesn't provide any way for an
application to speak through the system's global speech synthesizer. It is
possible for an app to do this (Apple software does) but you must use
private APIs, which Apple doesn't allow in apps that are published on the
app store. It also isn't possible for an accessible app to speak through
VoiceOver's voice, like is possible for OS X or Windows apps to do with
their screen readers. So, if you're making an app, and you want your app to
speak, you must license a text-to-speech engine to be specifically used by
your app. Since you must pass that licensing cost along to your users, that
is why those talking apps tend to cost more than most apps
I don't know the exact reason for this. My only guess is that Apple has a
special license with Nuance that gives them distribution rights to Vocalizer
at an extremely low per-unit cost, with the qualification that they only use
it with Apple software. Nuance, for example, will happily sell an developer
a license to use Vocalizer, which is already installed on all of the newer
Apple mobile devices.
Someone told me that the TTS situation had changed in iOS 4. Supposedly,
apps can now speak directly with the system voice. However, I've been unable
to find any official confirmation of this, or technical docs on how to
accomplish it.
Until then, though, these book readers will either be missing any Daisy text
support, or else will have to jack up their prices to pay for a speech synth
license. Is too bad. There is a lot more Daisy material out there in text
form than audio.
