sphinx-4 NullPointerException在startRecognition

我試圖關注this tutorial，並且它在啓動後崩潰了很多字典和模型的問題，例如。sphinx-4 NullPointerException在startRecognition

The dictionary is missing a phonetic transcription for the word 'humphrey'

和

Dec 18, 2014 1:14:50 PM edu.cmu.sphinx.linguist.lextree.HMMTree addPronunciation SEVERE: Missing HMM for unit T with lc=N rc=EH1 13:14:50.601 SEVERE lexTreeLinguist Bad HMM Unit: EH1

我裝this dictionary並得到了their SourceForge page

語言和聲學模型隨後，應用此崩潰：

這是我的代碼。

package com.test.sphinxtest; 

import java.io.IOException; 

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

/** 
* Hello world! 
* 
*/ 
public class App 
{ 
    public static void main(String[] args) 
    { 
     Configuration configuration = new Configuration(); 

     configuration.setAcousticModelPath("models/acousticmodel/en-us"); 
     configuration.setDictionaryPath("dictionary/cmudict-0.6d"); 
     configuration.setLanguageModelPath("models/languagemodel/en-us.lm"); 

     try { 
      LiveSpeechRecognizer recognizer = new LiveSpeechRecognizer(configuration); 
      recognizer.startRecognition(true); 
      SpeechResult result = recognizer.getResult(); 
      recognizer.stopRecognition(); 
      while ((result = recognizer.getResult()) != null) { 
       System.out.println(result.getHypothesis()); 
      } 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
    } 
}

正確的字典不應該有壓力的痕跡，你可以從這裏下載：

是什麼意思了一本字典是「正確」？我如何知道哪些是「正確的」，哪些是「不正確的」？ – Houseman

詞典手機必須匹配聲學模型的手機。如果它匹配字典是正確的，否則不正確，你會得到類似上面的錯誤。這個問題在教程中介紹。 –

本教程涵蓋了哪些問題？也許我正在看錯誤的教程，或者按順序或其他方式遵循它。 – Houseman
