Question

我对android.speech.SpeechRecognizer方法有一些疑问

speechRecognizer.startListening(speechIntent)

有时，播放“就绪”声音要花很长时间（通常是在应用重新运行之后）。我找不到类似onSpeechRecognitionReady的监听器。如何捕获此事件以创建progressBar？

我以此方式初始化识别器

private fun initSpeechRecognizer() {
        speechIntent = Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH)
        speechIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "en-US")
        speechIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, packageName)
        speechRecognizer = SpeechRecognizer.createSpeechRecognizer(this)
        speechRecognizer.setRecognitionListener(object : RecognitionListenerAdapter(){
            override fun onResults(results: Bundle) {
                val matches = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION)
                tv_speech.text = matches[0]
                btn_speech.isChecked = false
            }
        })
    }

我认为您应该使用具有RecognitionListener方法的onReadyForSpeech，以便可以在init上显示进度条，并在ReadyForSpeech上将其隐藏

现在，我必须执行此丑陋的操作。它会产生多余的开始聆听和停止聆听声音。
