title: VoiceService in iOS
body: <p>I have a question about understanding event changes in iOS when VoiceOver is enabled. I'm developing some app for blind people. </p>
  
  <p>Unfortunately there is not TTS support on iOS, differently from the Mac OS SDK where you can use NSSpeechSynthesizer objects. </p>
  
  <p>I found VoiceService the is not public. So, in conclusione it seems that no API for speak text is available on iOS.  </p>
  
  <p>The question is: How can I notify the user about data processing end? </p>
  
  <p>Here is a user case: User push button, the app make some calculus/process, than should return the result. In Mac this is easy you use speakString:@"Result". </p>
  
  <p>But how can I tell VoiceOver to announce the result?? </p>
  
  <p>Excuse me if I was too contort :-)</p>
  
  <p>Thank you very much... </p>
