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

我认为你的 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)

另外你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;
 }

更新

它只发生在较低级别的 SDK 设备上。一旦我添加了最新的speech-to-text 库，它就解决了。 'com.ibm.watson.developer_cloud:speech-to-text:3.8.1-SNAPSHOT' 安装在'com.ibm.watson.developer_cloud:speech-to-text:3.8.0' Info.

今天我从头开始了另一个 android 项目，但没有得到上述运行时异常。我已经设法从波形文件中取出文本。

例子：

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

            final File audio = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/about_time.wav");

            final RecognizeOptions options = new RecognizeOptions.Builder()
                    .continuous(false)
                    .model("en-US_NarrowbandModel")
                    .interimResults(true)
                    .contentType(HttpMediaType.AUDIO_WAV)
                    .build();



            new Thread(new Runnable() {
                public void run() {
                    SpeechResults transcript = service.recognize(audio, options).execute();
                    System.out.println(transcript);
                }
            }).start();
