title: Can we give a custom voice to AVSpeechSynthesizer
body: <p>Hi I am developing an IOS application and I want to convert text to speech. For this I am using IOS <code>AVSpeechSynthesizer</code> SDK.</p>
  
  <p>My question is that can we give it our custom voice other than the defaults voices of IOS. <strong>For example can I give the voice of a child speaking a string?</strong></p>
  
  <p>Or there is another SDK for that?
  And <code>AVSpeechSynthesizer</code> is only for IOS7 or can it work on IOS 6 as well?</p>
