Question

我想创建简单的Speech to Text应用程序，我找到了SpeechRecognizer类，它看起来像我需要的东西。

我已将这些权限添加到我的清单中：

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

然后在我的MainActivity中，只有一个button和一个textVew。我已经设置了我的活动onCreate，如下所示：

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

    textView = (TextView) findViewById(R.id.textView);
    button = (Button) findViewById(R.id.button);

    sr = SpeechRecognizer.createSpeechRecognizer(this);
    sr.setRecognitionListener(new MySpeechRecognitionListener());

    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
            intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
            intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 10);
            intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,"com.daniyar.speechrecogniitontest");
            sr.startListening(intent);
        }
    });
}

在我的MySpeechRecognitionListener中看起来像这样：

private class MySpeechRecognitionListener implements RecognitionListener {
    @Override
    public void onReadyForSpeech(Bundle bundle) {
        Toast.makeText(MainActivity.this, "Ready", Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onError(int i) {
        Toast.makeText(MainActivity.this, "Error " + i, Toast.LENGTH_LONG).show();
    }

  @Override
    public void onResults(Bundle bundle) {
        String str = "";
        ArrayList data = bundle.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
        for (int i = 0 ; i < data.size(); i++) {
            str += data.get(i);
        }

        textView.setText(str);
    }
}

当我启动我的应用程序然后点击按钮时，它会显示我Error 5的祝酒词，并在我的日志中显示一条消息：

SpeechRecognizer: no selected voice recognition service

如何设置识别服务？此外，是否可以离线使用SpeechRecognizer？

Android，SpeechRecognizer：没有选择的语音识别服务
