如何将IBM Watson Speech的关键字定位功能用于文本API？

Question

我正在使用IBM Watson Speech来发送文本API以将音频文件转换为文本。每个功能都适合我。但我无法使用关键字定位功能。输出没有提供有关被发现关键字的任何信息。

这是我的代码：

SpeechToText service = new SpeechToText();
    service.setUsernameAndPassword("*********", "********");
    //SpeechModel model =service.getModel("en-US_NarrowbandModel");


    service.setEndPoint("https://stream.watsonplatform.net/speech-to-text/api");

    String[] keys= {"abuse","bullying","parents","physical","assaulting"};
    RecognizeOptions options = new RecognizeOptions().contentType("audio/wav").model("en-US_NarrowbandModel").continuous(true).inactivityTimeout(500).keywords(keys).keywordsThreshold(0.7);


    File audio = new File("C:\\Users\\AudioFiles\\me.wav");

    SpeechResults transcript = service.recognize(audio, options);
    //Speech t1 = service.recognize(audio, options);
    System.out.println(transcript);

是否有任何特殊功能可以将带有关键字的关键字作为输出以及成绩单？

Answer 1

这已在Java SDK v3.2.0中修复。请务必下载最新版本（4.2.1）jar：java-sdk-4.2.1-jar-with-dependencies.jar或更新您的Gradle / Maven以获取最新版本。

以下代码基于您问题中的代码。

SpeechToText service = new SpeechToText();
service.setUsernameAndPassword("USERNAME", "PASSWORD");

File audio = new File("C:\\Users\\AudioFiles\\me.wav");    

RecognizeOptions options = new RecognizeOptions().Builder()
  .contentType("audio/wav)
  .inactivityTimeout(500)
  .keywords({"abuse", "bullying", "parents", "physical", "assaulting"})
  .keywordsThreshold(0.5)
  .build();

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