AVSpeechsynthesizer with the en-us voice is pronunciation for "A" is "Capital A" but Just want "A" How can do that?

推荐答案

这只会在字符串中有单个字符时发生，

This only happens when there is single character in the string,

您可以使用此解决方法来检查字符串的长度是否为 1，然后将其转换为小写字符串，

you can use this workaround of checking if lenght of string is 1 than convert it to lowercase string,

NSString *stringToUtter = @"A";
if (stringToUtter.length==1) {
    stringToUtter = [stringToUtter lowercaseString];
}
AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc] initWithString:stringToUtter];
utterance.rate = AVSpeechUtteranceMinimumSpeechRate;
utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"en-us"];
[self.synthesizer speakUtterance:utterance];
