Read out text in iOS

Is there a way or a lib which can read out 开发者_开发百科text?

Here is another one that does text-to-speech and also speech recognition

Hope this helps, Vincent

I haven't tried it out myself yet, but something existed at the end of last year: http://www.ahmed-essam.com/2010/11/ios-sdk-text-to-speech-in-one-line.html
