iOS 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.


Solution

  • Since 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
    synthesizer.speak(utterance)
    

    You can also change the voice like this :

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

    And then speek

    • In Swift 2 synthesizer.speakUtterance(utterance)

    • In Swift 3 synthesizer.speak(utterance)

    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).
