AVFAudio：AVAE_RaiseException（NSString*， ...） + 52

问：

当我单击按钮时，我想使用 Apple 的功能将对话附加到一个。 问题是我的应用程序有时会崩溃，我不知道我的代码中可能有什么问题。 我将在下面附上我的代码以及我的崩溃的回溯。 任何帮助将不胜感激！Start RecordingtextViewSpeechRecognizer

我的代码：

func startRecording() {
        
        startStopRecordBtn.setImage(UIImage(#imageLiteral(resourceName: "microphone_off")), for: .normal)
        if UserDefaults.standard.bool(forKey: Constants.darkTheme) {
            commentTextView.textColor = .white
        } else {
            commentTextView.textColor = .black
        }
        commentTextView.isUserInteractionEnabled = false
        recordingLabel.text = Constants.recording
        
        if recognitionTask != nil {
            recognitionTask?.cancel()
            recognitionTask = nil
        }
        
        let audioSession = AVAudioSession.sharedInstance()
        do {
            try audioSession.setCategory(AVAudioSession.Category.record)
            try audioSession.setMode(AVAudioSession.Mode.measurement)
            try audioSession.setActive(true, options: .notifyOthersOnDeactivation)
        } catch {
            showAlertWithTitle(message: Constants.error)
        }
        
        recognitionRequest = SFSpeechAudioBufferRecognitionRequest()
        
        let inputNode = audioEngine.inputNode
        
        guard let recognitionRequest = recognitionRequest else {
            fatalError(Constants.error)
        }
        
        recognitionRequest.shouldReportPartialResults = true
        
        recognitionTask = speechRecognizer?.recognitionTask(with: recognitionRequest, resultHandler: { (result, error) in
            
            var isFinal = false
            
            if result != nil {
                
                self.commentTextView.text = result?.bestTranscription.formattedString
                isFinal = (result?.isFinal)!
            }
            
            if error != nil || isFinal {
                self.audioEngine.stop()
                inputNode.removeTap(onBus: 0)
                
                self.recognitionRequest = nil
                self.recognitionTask = nil
                
                self.startStopRecordBtn.isEnabled = true
            }
        })
        
        let recordingFormat = inputNode.outputFormat(forBus: 0)
        inputNode.installTap(onBus: 0, bufferSize: 1024, format: recordingFormat) { (buffer, when) in
            self.recognitionRequest?.append(buffer)
        }
        
        audioEngine.prepare()
        
        do {
            try audioEngine.start()
        } catch {
            showAlertWithTitle(message: Constants.error)
        }
    }
