                NSString* msg = @"Hello, how are you?";
                AVSpeechUtterance *utterance = [AVSpeechUtterance
                                                speechUtteranceWithString: msg];
                utterance.rate = AVSpeechUtteranceMaximumSpeechRate;
                utterance.pitchMultiplier = 1.0f;
                utterance.voice =[AVSpeechSynthesisVoice voiceWithLanguage:@"en-US"];
                utterance.volume = 1.0f;
                utterance.postUtteranceDelay = 5;
                AVSpeechSynthesizer *synth = [[AVSpeechSynthesizer alloc] init];
                synth.delegate = self;
                [self log:@"Start Speech"];
                [synth speakUtterance:utterance];


        Is it a bug on speech framework? It works on iOS 10, but now it doesn't work on iOS 11. I heard the voice of speech, but it never call didFinishSpeechUtterance.
