Run TTS in NSArray sequentially

I have NSArray with words in it. I want to app reads that tts sequentially and print the text in UILabel what app speak. but word on label is shown the last one.

I tried time pause, etc

for (Word * w in ttswords) {
    [self speechword:w];
}

-(void)speechword:(Word*)w{

    utterance = [[AVSpeechUtterance alloc] initWithString:[w.title stringByReplacingOccurrencesOfString:@"~" withString:@""]];
    utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:@"en-US"];
    [synthesizer speakUtterance:utterance];

    _lb_title.text = w.title;

}

I want to execute one by one.

The best way to highlight the vocalized word is using the speechSynthesizer:willSpeakRangeOfSpeechString:utterance: method of the AVSpeechSynthesizerDelegate protocol.

If you don't use this delegate method, you won't be able to reach your goal.

Take a look at this complete and useful example (ObjC and Swift) that displays each vocalized word in a bold font with the speech synthesis.
