Answer 1

使用起来相当简单:

private void startVoiceRecognitionActivity() {
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    //uses free form text input
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
        RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    //Puts a customized message to the prompt
    intent.putExtra(RecognizerIntent.EXTRA_PROMPT,
        getString(R.string.listenprompt));
    startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);
}

/**
 * Handles the results from the recognition activity.
 */
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == VOICE_RECOGNITION_REQUEST_CODE && resultCode == RESULT_OK) {
        // Fill the list view with the strings the recognizer thought it could have heard
        ArrayList<String> matches = data.getStringArrayListExtra(
                RecognizerIntent.EXTRA_RESULTS);

        //Turn on or off bluetooth here
    } else {
        super.onActivityResult(requestCode, resultCode, data);
    }
}

然后在您需要的任何地方从您的代码中调用 startVoiceRecognitionActivity()。当然你需要有访问互联网的权限

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

在你的 Android.manifest 中。
