Voice Output in iOS

问题

Is it possible to access the speech synthesis feature of the iOS that is used for accessibility?

回答1:

Here is an example using AVSpeechSynthesizer on iOS 7:

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

To change the voice use:

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

To get a list of all voices:

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