Question

我使用android.speech.SpeechRecognizer，只有通过蓝牙连接到配对手机才能正常工作。如果我停用手机的蓝牙，SpeechRecognizer将停止工作。这适用于与iPhone或Android手机配对。活跃的电话连接真的是一个约束吗？

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

您只需使用startActivityForResult设置来调用ACTION_RECOGNIZE_SPEECH，这将启动活动并通过onActivityResult

返回数据

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);
}

只有Android Wear连接到智能手机时，SpeechRecognizer才可用吗？
