SpeechRecognizer僅在Android Wear連接到智能手機時纔可用？

Question

我正在使用android.speech.SpeechRecognizer，它似乎只在通過藍牙連接到配對手機時才起作用。如果我禁用手機的藍牙，SpeechRecognizer將停止工作。這適用於與iPhone或Android手機配對。活動的電話連接真的是一個限制嗎？

檢查文檔時，它看起來仍然可以通過使用系統的SpeechRecognizer活動完成。

你只需要調用startActivityForResult與ACTION_RECOGNIZE_SPEECH集，這將啓動活動並返回數據直通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); 
}
