Question

我正在使用SpeechRecognizer尝试获取一些德语字符串。我正在通过Google Translate德语录音（例如，“你好吗？” - ＆gt;“Wie geht es Ihnen？”）。

我看过几个关于如何改变语言以接受除英语之外的其他语言的问题/答案，但似乎都没有。

在将设备的语言设置保持为英语（en-US）的同时，是否有人知道如何执行此操作？

只有当我将设备的语言设置为“de-DE”时，我才能成功获取德语字符串。

这是我的示例代码：

public class MainActivity extends Activity {

    private static final String TAG = MainActivity.class.getSimpleName();
    Button mSpeakBtn;
    TextView mResultTextView;
    SpeechRecognizer mSpeechRecognizer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Init Views
        mSpeakBtn = (Button) findViewById(R.id.speak_btn);
        mResultTextView = (TextView) findViewById(R.id.result_tv);

        // Set click listener for button
        mSpeakBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mResultTextView.setText("Speak now...");

                mSpeechRecognizer = SpeechRecognizer.createSpeechRecognizer(getApplicationContext());
                mSpeechRecognizer.setRecognitionListener(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() {
                        mResultTextView.setText("Processing...");
                    }

                    @Override
                    public void onError(int error) {
                        mResultTextView.setText("ERROR: " + error);
                    }

                    @Override
                    public void onResults(Bundle results) {
                        List<String> allWords = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
                        Log.d(TAG, "onResults:\t" + allWords.toString());
                        String result = allWords.get(0);
                        mResultTextView.setText("RESULT: '" + result + "'");
                    }

                    @Override
                    public void onPartialResults(Bundle partialResults) {

                    }

                    @Override
                    public void onEvent(int eventType, Bundle params) {

                    }
                });

                String locale = Locale.GERMANY.toString().replace("_", "-");
                Log.d(TAG, "Locale:\t" + locale);

                Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
                intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, locale);
                intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, locale);
                intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getApplication().getPackageName());
                intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH);
                mSpeechRecognizer.startListening(intent);
            }
        });
    }
}

我也尝试过，我只会这样做：

Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, locale);
mSpeechRecognizer.startListening(intent);

但结果是一样的 - 获得德语言的'英语'翻译。

任何指针？
