在iOS 5或6中没有内置的文本到语音支持 - 您需要使用第三方库.如果你使用的是iOS 7,那么你很幸运.

在iOS 7中有一个新类叫AVSpeechSynthesizer(Apple的文档可以在这里找到).您可以使用它来执行文本到语音转换.这是一个简单的例子:

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

[synth speakUtterance:utterance];

速度和语音类型等属性设置在AVSpeechUtterance合成器中,而不是合成器中.
