Answer 1

You can set one of the bellow language:

 for (AVSpeechSynthesisVoice *voice in [AVSpeechSynthesisVoice speechVoices]) {
            NSLog(@" %@", voice.language);
        }

or use default locale:

AVSpeechSynthesizer *synthesizer = [[AVSpeechSynthesizer alloc] init];
AVSpeechUtterance *utterance = [AVSpeechUtterance speechUtteranceWithString:@"Localized -text"];
 utterance.rate = AVSpeechUtteranceMinimumSpeechRate; // Tell it to me slowly
[synthesizer speakUtterance:utterance];

Answer 2

SWIFT 3 update:

import AVFoundation

(check the languages codes):

for voice in (AVSpeechSynthesisVoice.speechVoices()){
        print(voice.language)
    }

Then:

let speakTalk   = AVSpeechSynthesizer()
let speakMsg    = AVSpeechUtterance(string: "Hello World, I can speak")

speakMsg.voice  = AVSpeechSynthesisVoice(language: "en-US")
speakMsg.pitchMultiplier = 1.2
speakMsg.rate   = 0.5

speakTalk.speak(speakMsg)
