iPhone - API for Text to Speech feature [closed]

I ran into this problem at one point, and got Flite (festival lite) text to speech engine running on iPhone. I recently made an API class for it. I tried to make it easy (and free) to add to new and existing projects. It can be downloaded at here.

The iPhone 3G S has the private VoiceServices framework which can do this. Steve Troughton-Smith describes how to use the private class VSSpeechSynthesizer here, but you have little chance of getting something using this into the App Store.

For iOS 5 or 6 - nothing built-in. You need to use a third party library.

For iOS 7 there is a AVSpeechSynthesizer API.

Here's a simple example:

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