我正在尝试使用 IBM Watson 的 Android 语音转文本库。我注意到这里有一个类似的问题，但没有给出答案。我已经集成了所有内容，但是在尝试启动识别服务时，出现此错误：

我的代码在这里：

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    //setSupportActionBar(toolbar);

    txtSpeechInput = (TextView) findViewById(R.id.textINput);
    btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);
    btnSpeak.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            //promptSpeechInput();
            //set();
            SpeechToText.sharedInstance().recognize();
        }
    });
    btnEnd = (ImageButton) findViewById(R.id.btnEnd);
    btnEnd.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            SpeechToText.sharedInstance().stopRecording();

        }
    });


    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.setDrawerListener(toggle);
    toggle.syncState();

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

    // Configuration
    SpeechConfiguration sConfig = new SpeechConfiguration(SpeechConfiguration.AUDIO_FORMAT_OGGOPUS);
    // STT
    SpeechToText.sharedInstance().initWithContext(this.getHost("https://gateway.watsonplatform.net/conversation/api"), this.getApplicationContext(), sConfig);
    SpeechToText.sharedInstance().setCredentials("PERSONAL","INFO");
    SpeechToText.sharedInstance().setDelegate(this);

我需要使用下面的代码，该代码来自 nuance 示例

Session session = Session.Factory.session(this, com.intellidev.mobitranscribe.Configuration.SERVER_URI,
                com.intellidev.mobitranscribe.Configuration.APP_KEY);

        Transaction.Options options = new Transaction.Options();
        options.setRecognitionType(RecognitionType.DICTATION);
        options.setDetection(DetectionType.Long);
        options.setLanguage(new Language("ENG-USA"));

        //Start listening
        recoTransaction = speechSession.recognize(options, recoListener);
