解决方案:它没有US male voice
我已经习惯AVSpeechSynthesizer framework了iOS7.0
AVSpeechUtterance *utt = [AVSpeechUtterance speechUtteranceWithString:@"Hello"];
if (isMale) //flag for male or female voice selected
{
// need US male voice as en-US is providing only US female voice
utt.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"en-GB"]; //UK male voice
}
else
{
utt.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"en-US"]; //US female voice
}

我需要用US male voice而不是male UK voice.
