为什么SFSpeechRecognizer在ipad中不起作用

如何解决为什么SFSpeechRecognizer在ipad中不起作用

SFSpeechRecognizer在IOS中运行良好 但是它在IPAD中不可用。 我不知道该如何解决。 请给我一个解决方案。

func recordAndRecognizeSpeech() {
        
        let node = audioEngine.inputNode
        let recordingFormat = node.outputFormat(forBus: 0)
        node.installTap(onBus: 0,bufferSize: 0,format: recordingFormat) { buffer,_ in
            self.request.append(buffer)
        }
        audioEngine.prepare()
        do {
            try audioEngine.start()
        } catch {
            return print(error)
        }
        guard let myRecognizer = SFSpeechRecognizer() else {
            // A recognizer is not supported for the current locale
            return
        }
        if !myRecognizer.isAvailable {
            print("Speech recognition not available")
            return
        }
        isFinal = false

        recognitionTask = speechRecognizer?.recognitionTask(with: request,resultHandler:  { result,error in
            if let result = result {
                self.recognizedSpeechTextView.text = result.bestTranscription.formattedString
                self.qnaTextField.text = result.bestTranscription.formattedString
                self.textFieldDidChange(self.qnaTextField)

            } else if let error = error {
                print(error)
            }
            
            if !self.isFinal {
                self.startSpeechTimer()
            }
        })
    }

在iPad通话中

如果！myRecognizer.isAvailable { 打印（“语音识别不可用”） 返回 }
