SpeechRecognizer仅在Android Wear连接到智能手机时才可用？

Question

我正在使用android.speech.SpeechRecognizer，它似乎只在通过蓝牙连接到配对手机时才起作用。如果我禁用手机的蓝牙，SpeechRecognizer将停止工作。这适用于与iPhone或Android手机配对。活动的电话连接真的是一个限制吗？

检查文档时，它看起来仍然可以通过使用系统的SpeechRecognizer活动完成。

你只需要调用startActivityForResult与ACTION_RECOGNIZE_SPEECH集，这将启动活动并返回数据直通onActivityResult

private static final int SPEECH_REQUEST_CODE = 0; 

// Create an intent that can start the Speech Recognizer activity 
private void displaySpeechRecognizer() { 
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); 
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, 
    RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); 
    // Start the activity, the intent will be populated with the speech text 
    startActivityForResult(intent, SPEECH_REQUEST_CODE); 
} 

// This callback is invoked when the Speech Recognizer returns. 
// This is where you process the intent and extract the speech text from the intent. 
@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (requestCode == SPEECH_REQUEST_CODE && resultCode == RESULT_OK) { 
     List<String> results = data.getStringArrayListExtra(
     RecognizerIntent.EXTRA_RESULTS); 
     String spokenText = results.get(0); 
     // Do something with spokenText 
    } 
    super.onActivityResult(requestCode, resultCode, data); 
}
