导读：我想读一篇很长的文字： NSString *text =@"Long test with dot. I want speaching pause when read dot. How can I do?";AVSpeechSynthesizer *synthesizer = [AVSpeechSynthesizer new];[synthesizer setDelegate:self];AVSpeechUtterance *utterance = [[

我想读一篇很长的文字：

NSString *text =@"Long test with dot. I want speaching pause when read dot. How can I do?";
AVSpeechSynthesizer *synthesizer = [AVSpeechSynthesizer new];
[synthesizer setDelegate:self];
AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc] initWithString:text];
        utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:[self.defaults objectForKey:LANGUAGE]];
        utterance.rate = 0.28;
        [synthesizer speakUtterance:utterance];

我想合成器检测点并暂停100毫秒.

可能吗？我能怎么做？？

解决方法

我的意思是一个点(.)

但也许我找到了一个解决方案也是字符”,’：

NSString *text = @"Line one. LineTwo aftre a pause. Line three,pause here again.";
        text = [text stringByReplacingOccurrencesOfString:@"," withString:@"."];

        NSArray *a = [text componentsSeparatedByString:@"."];
        for(NSString *line in a)
           {
           AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc] initWithString:line];
           utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:[self.defaults objectForKey:LINGUA]];
           utterance.rate = 0.28;
           utterance.**postUtteranceDelay** = 0.3;
           [self.synthesizer speakUtterance:utterance];
           }
