java - SpeechToText IBM Watson ExceptionInInitializerError

Question

我在测试 IBM Watson SpeechToText Api 时遇到问题。

  SpeechToText service = new SpeechToText();
        service.setUsernameAndPassword("<UserName>", "<Password>");

        File audio = new File(Environment.getExternalStorageDirectory().getAbsolutePath()
                +MEDIA_FOLDER+"/myaudio.amr");

        SpeechResults transcript = service.recognize(audio).execute();
        System.out.println(transcript);

我在SpeechToText service = new SpeechToText();行收到java.lang.ExceptionInInitializerError错误

错误

Answer 1

我认为您的 setUsernameAndPassword 是错误的。它应该是:setCredentials(字符串用户名，字符串密码)除非它是您的自定义函数。

在链接底部，找到函数:setCredentials(String username, String password)

您还需要初始化共享实例并使用它，

     /**
     * Init the shared instance with the context
     * @param uri
     * @param ctx
     * @param sc
     */
    public void initWithContext(URI uri, Context ctx, SpeechConfiguration sc){
        this.setHostURL(uri);
        this.appCtx = ctx;
        this.sConfig = sc;
    }

尝试按照快速入门指南中提供的此步骤进行操作。

private boolean initSTT() {
     // initialize the connection to the Watson STT service
     String username = getString(R.string.STTdefaultUsername);
     String password = getString(R.string.STTdefaultPassword);
     String tokenFactoryURL = getString(R.string.STTdefaultTokenFactory);
     String serviceURL = "wss://stream.watsonplatform.net/speech-to-text/api";
     SpeechConfiguration sConfig = new SpeechConfiguration(SpeechConfiguration.AUDIO_FORMAT_OGGOPUS);
     SpeechToText.sharedInstance().initWithContext(this.getHost(serviceURL), getActivity().getApplicationContext(), sConfig);
     // Basic Authentication
     SpeechToText.sharedInstance().setCredentials(username, password);
     SpeechToText.sharedInstance().setModel(getString(R.string.modelDefault));
     SpeechToText.sharedInstance().setDelegate(this);
     return true;
 }
