I am developing an application in which I have to play string as an audio.

I am using http://translate.google.com/translate_tts?tl=en&q=Hello API to speak the string but it is a little bit slow.

Is there any library in objective-c to play string as an audio "Text To Speech".

查看 io7 中的 AVSpeechUtterance 和 AVSpeechSynthesizer 类。基本上你可以做到以下几点。

     AVSpeechUtterance *utterance = [AVSpeechUtterance speechUtteranceWithString:text];
     AVSpeechSynthesizer *syn = [[[AVSpeechSynthesizer alloc] init]autorelease];
    [syn speakUtterance:utterance];

导入框架：

#import <AVFoundation/AVFoundation.h>
#import <QuartzCore/QuartzCore.h>

.m 文件代码

NSString *str = @"Hello friend, how are you?";

AVSpeechSynthesizer *synthesizer = [[AVSpeechSynthesizer alloc]init];

AVSpeechUtterance *speechutt = [AVSpeechUtterance speechUtteranceWithString:strtext];
 speechutt.volume=90.0f;
 speechutt.rate=0.50f;
 speechutt.pitchMultiplier=0.80f;
[speechutt setRate:0.3f];
speechutt.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"en-us"];
[synthesizer speakUtterance:speechutt];

任何语言的voiceWithLanguage 选项都支持这一点。

Nuance NDEV Mobile iOS SDK在质量和性能方面可能是您的最佳选择，但与 OpenEars 不同的是它不是免费的。也就是说，我们有 40 种不同的语言和 61 种不同的声音可用​​，并且该库有一个不依赖于 HTTP（并且仍然基于网络）的子系统，您可以使用它。

一旦你注册了一个帐户..

  • 创建一个意图使用 iOS 平台的应用程序
  • 下载 iOS SDK（那里有一个示例应用程序，但我将描述将其集成到您的应用程序中的过程）
  • 导入 SpeechKit.framework 和相关的框架（参见文档）
  • 从上面创建的应用程序的信息中指定凭据
  • SpeechKit使用该信息进行初始化
  • 创建Vocalizer实例，指定语言或语音
  • 将该Vocalizer实例speakString与您要合成的文本一起使用
  • 处理委托方法：
    • willBeginSpeakingString:(NSString *)text
    • didFinishSpeakingString:(NSString *)text

注意：Vocalizer API 也支持SSML。
