iOS中的语音输出

Question

是否可以访问用于辅助功能的iOS语音合成功能？

Answer 1

以下是AVSpeechSynthesizer在iOS 7上使用的示例:

AVSpeechSynthesizer *synthesizer = [[AVSpeechSynthesizer alloc]init];
AVSpeechUtterance *utterance = [AVSpeechUtterance speechUtteranceWithString:@"Hey Guys"];
[synthesizer speakUtterance:utterance];

要改变语音使用:

utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"de-DE"];

获取所有声音的列表:

NSLog(@"voices %@", [AVSpeechSynthesisVoice speechVoices]);
