How does text-to-speech shortcut read any highlighted text?

Question

Hi, I am trying to develop a cocoa application that requires to read highlighted text from any application. But so far I cannot find any decent solution because the accessibility API isn't always work. (e.g. Firefox) Does anyone know how it is implemented in text-to-speech included in Leopard?

I have found this SO question but it isn't solved.

Answer 1

That's a Service, so anywhere that an application identifies its selection as text, the text-to-speech service will work.
