Question

我有英文/法文申请。定义EXTRA_LANGUAGE_PREFERENCE是不够的。只要我更改系统语言输入以映射目标所需语言，我的应用程序就能正常运行。

知道我做错了什么吗？以下是我正在使用的代码。

private void initSpeech(){
    Context context;
    context = getActivity().getApplicationContext();
    speech = SpeechRecognizer.createSpeechRecognizer(context);
    mListener = new RecognitionListener() {
        @Override
        public void onReadyForSpeech(Bundle params) {

        }

        @Override
        public void onBeginningOfSpeech() {

        }

        @Override
        public void onRmsChanged(float rmsdB) {

        }

        @Override
        public void onBufferReceived(byte[] buffer) {

        }

        @Override
        public void onEndOfSpeech() {

        }

        @Override
        public void onError(int error) {

        }

        @Override
        public void onResults(Bundle results) {
            String s = null;
            int ifl = 0;

            ArrayList<String> thingsYouSaid = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);

            spoken.setVisibility(View.VISIBLE);
            assert thingsYouSaid != null;
            for(int i = 0; i<thingsYouSaid.size(); i++) {
                if(thingsYouSaid.get(i).equals(words[curr_pos])) {
                    ((TextView) getActivity().findViewById(R.id.dict_spoken_word)).setText(thingsYouSaid.get(i));
                    ifl = 1;
                    s = thingsYouSaid.get(i);
                    break;
                }
            }
            if(ifl == 0) {
                s = thingsYouSaid.get(0);
                ((TextView) getActivity().findViewById(R.id.dict_spoken_word)).setText(thingsYouSaid.get(0));
            }

            excellent.setVisibility(View.VISIBLE);
            if (lang == 0) {
                if (s.equals(words[curr_pos])) {
                    excellent.setTextColor(Color.GREEN);
                    excellent.setText(R.string.dict_resp);
                    count = 0;
                    return;
                }
                count++;
                excellent.setTextColor(Color.BLUE);
                if (count == 1) {
                    excellent.setText(R.string.dict_resp1);
                } else if (count == 2)

为了在不改变语言环境的情况下更改语言，我使用了here所描述的技术。我能够获得一个测试应用程序用法语转录，而我的语言环境是美国：

private void initSpeech(){
    ...
    String myLanguage;
    if (!isFrench) {
      myLanguage = "en-US";
    } else {
      myLanguage = "fr";
    }
    recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, myLanguage);
    recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, myLanguage);
    recognizerIntent.putExtra(RecognizerIntent.EXTRA_ONLY_RETURN_LANGUAGE_PREFERENCE, myLanguage);
    ...
}

您需要确保在语言发生变化时随时拨打initSpeech()，或者意图仍然会使用旧的语言标记。

语言识别仅在我更改系统语言输入时才有效
