There is no built in text-to-speech support in iOS 5 or 6 - you'll need to use a third party library. If you are using iOS 7 you're in luck.

There's a new class in iOS 7 called AVSpeechSynthesizer (Apple's docs can be found here). You can use this to perform text-to-speech. Here's a simple example:

AVSpeechUtterance *utterance = [AVSpeechUtterance 
                                speechUtteranceWithString:@"Hello world"];
AVSpeechSynthesizer *synth = [[AVSpeechSynthesizer alloc] init];

[synth speakUtterance:utterance];

Properties such as speed and voice type are set in the AVSpeechUtterance, rather than the synthesizer.
