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java.lang.ExceptionInInitializerError行

时出现SpeechToText service = new SpeechToText();错误

错误

Answer 1

我认为你的setUsernameAndPassword是错误的。它应该是：setCredentials（String username，String password）除非它是你的自定义功能。

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

您还需要初始化共享实例并使用它，

foreach(XElement iceCream in Icecreams.Elements("Icecream"))
{
    XElement IcecreamsList = new XElement("IcecreamsList",
            (from c in iceCream.Elements("Flavor")
            orderby c.Value ascending
            select c));
    for (int i = 0; i < iceCream.Elements("Flavor").Count();i++)
    {
        iceCream.Elements("Flavor").ToList()[i].ReplaceWith(IcecreamsList.Elements("Flavor").ToList()[i]);
    }
}

Icecreams.Save(YOUR_PATH);

请尝试按照快速入门指南中提供的步骤进行操作。

     /**
     * 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;
    }

更新

它仅发生在较低级别的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' 'com.ibm.watson.developer_cloud:speech-to-text:3.8.0' {} Info

今天我从头开始另一个Android项目并没有得到上面的运行时异常。我已经设法从波形文件中获取文本。

示例：

 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();
