在 CMU Sphinx4 中禁用控制台消息

Question

我正在尝试 CMUSphinx，但我遇到了困难。我已将core 和data jar 包含到我从here 下载的Eclipse 项目中

我尝试像in the tutorial 中提到的那样进行实时语音识别，但是当我尝试运行它时，控制台充满了某种错误，例如The dictionary is missing a phonetic transcription for the word '....' 等等。

代码：

import edu.cmu.sphinx.api.Configuration;
import edu.cmu.sphinx.api.LiveSpeechRecognizer;
import edu.cmu.sphinx.api.SpeechResult;

public class Hello {       

   public static void main(String[] args) throws Exception {
    Configuration configuration = new Configuration();


    configuration.setAcousticModelPath("resource:/edu/cmu/sphinx/models/en-us/en-us");

    configuration.setDictionaryPath("resource:/edu/cmu/sphinx/models/en-us/cmudict-en-us.dict");

    configuration.setLanguageModelPath("resource:/edu/cmu/sphinx/models/en-us/en-us.lm.bin");
    LiveSpeechRecognizer recognizer = new LiveSpeechRecognizer(configuration);

    while(true)
    {
    System.out.println("Start speaking...");
    recognizer.startRecognition(true);
    SpeechResult result = recognizer.getResult();
    System.out.println("result: "+result.getHypothesis());

    recognizer.stopRecognition();
    }

}
}

控制台：

我已经下载了推荐的jars并包含在项目中。那么它有什么问题呢？他们没有提供字典吗？我可以添加缺少的phonetic transcription 吗？如果是，请提供链接。最后，我怎样才能禁用所有控制台警告等，并且只有我提供的输出。

Answer 1

我有同样的问题，我使用的唯一类是 StreamSpeechRecognizer 和 Configuration。在查看了 ConfigurationManagerUtils 的 sphinx 源之后，我设法在我自己的类中获取了以下代码，以禁用 edu.cmu.sphinx 包中的所有控制台日志记录。在实例化识别器之前放置此代码。

  Logger cmRootLogger = Logger.getLogger("default.config");
  cmRootLogger.setLevel(java.util.logging.Level.OFF);
  String conFile = System.getProperty("java.util.logging.config.file");
  if (conFile == null) {
        System.setProperty("java.util.logging.config.file", "ignoreAllSphinx4LoggingOutput");
  }

不太优雅，但它对我有用，除非有人有一种更简洁的方法来通过 sphinx 配置/上下文类在 runtime 禁用日志记录。

与我需要在自己的项目中使用的任何第三方包一样，我有充分的理由直接在代码中执行此操作，因为 1/ 我不关心公开任何第三方日志记录并且 2/ 我不希望为第三方代码提供定制的日志记录配置文件。
