ios - 如何获取 iOS 7 AVSpeechUtterance 文本到语音的不同语言代码？

Question

我想使用 iOS 7 新的语音合成 API，我的应用程序本地化为法语和英语、德语、日语等。我想设置语言代码来阅读文本。如何获取语言代码？

utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"en-ZA"];

Answer 1

您可以设置以下语言之一：

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

或使用默认语言环境：

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

Answer 2

斯威夫特 3 更新：

import AVFoundation

（检查语言代码）：

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

然后：

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)
