AVSpeechSynthesizer – 如何检测点毫秒暂停(iPHONE – iPADiOS7 xcode)

概述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];AV 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];           }
