可以在Epson bt 300中进行语音识别吗？ E / SpeechRecognizer：没有选定的语音识别服务

Question

我正在尝试基于语音识别在epson bt 300中开发一个模块。

我实现了类：RecognitionListener，这是我的代码：

public class VoiceRecognitionActivity extends AppCompatActivity implements
    RecognitionListener {

private static final int REQUEST_RECORD_PERMISSION = 1000;
private TextView returnedText;
private ToggleButton toggleButton;
private ProgressBar progressBar;
private SpeechRecognizer speech = null;
private Intent recognizerIntent;
private String LOG_TAG = "VoiceRecognitionActivity";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.voice_recognition_activity);
    speech = SpeechRecognizer.createSpeechRecognizer(this);

    Log.i(LOG_TAG, "isRecognitionAvailable: " + SpeechRecognizer.isRecognitionAvailable(this));

结果如下：

  

E / SpeechRecognizer：没有选定的语音识别服务

有谁知道动机？语音识别能否在epson bt 300中实现？

目前的版本是：Android 5.1
