텍스트에 대한 Siri의 연설은 작동하지 않습니다.

Question

텍스트에 대한 siri의 연설을 다루고 있습니다. 그러나 나는 audioEngine의 응답이 없습니다.

audioEngine은 음성의 첫 번째 텍스트를 인식 한 후 한 번 시작되고 일정 시간 동안 음성을 인식하기를 원하기 때문에 중지됩니다. 모든 제안을 부탁드립니다. 여기

는 지금까지 코드 짓을한다 :

NSLocale *locale = [NSLocale localeWithLocaleIdentifier:@"en-US"]; 
speechRecognizer = [[SFSpeechRecognizer alloc]initWithLocale: locale]; 

audioEngine = [[AVAudioEngine alloc]init]; 

if (speechRecognitionTask != nil) { 
    [audioEngine stop]; 
    [speechRecognitionTask cancel]; 
    speechRecognitionTask = nil; 
} 


AVAudioSession *audioSession = [AVAudioSession sharedInstance]; 

NSError *error = nil; 

if(error == nil) { 
    [audioSession setCategory:AVAudioSessionCategoryRecord error:&error]; 
    [audioSession setMode:AVAudioSessionModeMeasurement error:&error]; 
    [audioSession setActive:true error:&error]; 

} else 
    NSLog(@"audioSession properties weren't set because of an error."); 

recognitionRequest = [[SFSpeechAudioBufferRecognitionRequest alloc] init]; 

AVAudioInputNode *inputNode = audioEngine.inputNode; 

if (inputNode == nil) { 
    NSLog(@"AudioEngine has no input node"); 
    return; 
} 
recognitionRequest.shouldReportPartialResults = true; 
error = nil; 


speechRecognitionTask = [speechRecognizer recognitionTaskWithRequest:recognitionRequest resultHandler:^(SFSpeechRecognitionResult * result, NSError * error1) { 

    BOOL isFinal = false; 

    if (result != nil) { 
     self.textView.text = result.bestTranscription.formattedString; 
     isFinal = ![result isFinal]; 
     [audioEngine stop]; 
     [inputNode removeTapOnBus: 0]; 

     recognitionRequest = nil; 
     speechRecognitionTask = nil; 

AVAudioFormat *recodringFormat = [inputNode outputFormatForBus:0]; 

[inputNode installTapOnBus:0 bufferSize:1024 format:recodringFormat block:^(AVAudioPCMBuffer * _Nonnull buffer, AVAudioTime * _Nonnull when) { 
    [recognitionRequest appendAudioPCMBuffer:buffer]; 
}]; 

NSError *error1; 
[audioEngine prepare]; 

[audioEngine startAndReturnError:&error1]; 
if (error1 != nil) { 
    NSLog(@"Error discription: %@", error1.description); 
}
