Question

我使用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发现的关键字作为输出以及成绩单？

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);

如何将IBM Waston Speech的关键字定位功能用于文本API？
