java - 语音识别在android中超时太快

Question

这个函数启动了语音识别，但是超时太快了，好像是语音识别从 IME 键盘(例如 Google 键盘)启动，它不会很快超时。我需要一种方法来启动与谷歌键盘所使用的相同的 Intent 。

public void StartSpeechRecognitionActivity(){
    try{
        Intent intent = new   Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getClass().getPackage().getName());
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        intent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS, true);
        intent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_POSSIBLY_COMPLETE_SILENCE_LENGTH_MILLIS, 3000);
        intent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS, 3000);
        main.startActivityForResult(intent, SPEECHRECOGNITION_RESULTCODE);
    } catch (ActivityNotFoundException error) {
        ShowAndSpeakMessage("Speech recognition is not supported by your device");
    } catch( RuntimeException error ) {
        Log.e( TAG, ERROR_PREFIX + Errors.toString(error) );
    } catch( Error error ) {
        Log.e( TAG, ERROR_PREFIX + Errors.toString(error) );
        throw error;
    }
}

Answer 1

Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,
                            "Voice recognition!");
startActivityForResult(intent, REQUEST_CODE);

这对我来说很好用!
