iOS 7 Text To Speech Api

I can't seem to find anything on this. Are there any Siri classes or API's in iOS7 that let you do text to speech? All I am trying to do is something like the following:

[siriInstance say:@"This is a test"];

And then have Siri say it from my app.

It seems we should be capable of doing this, no? Seems like a trivial thing.

Answer Source

With iOS 7 you have a new TTS Api.

In Objective C

AVSpeechSynthesizer *synthesizer = [[AVSpeechSynthesizer alloc]init];
AVSpeechUtterance *utterance = [AVSpeechUtterance speechUtteranceWithString:@"Some text"];
[utterance setRate:0.2f];
[synthesizer speakUtterance:utterance];

In Swift

let synthesizer = AVSpeechSynthesizer()
let utterance = AVSpeechUtterance(string: "Some text")
utterance.rate = 0.2

You can also change the voice like this :

utterance.voice = AVSpeechSynthesisVoice(language: "fr-FR")

And then speek


Don't forget to import AVFoundation

Helpful methods

You can Stop or Pause all speech using these two methods :

- (BOOL)pauseSpeakingAtBoundary:(AVSpeechBoundary)boundary;
- (BOOL)stopSpeakingAtBoundary:(AVSpeechBoundary)boundary;

The AVSpeechBoundary indicates if the speech should pause or stop immediately (AVSpeechBoundaryImmediate) or it should pause or stop after the word currently being spoken (AVSpeechBoundaryWord).
