Question

我试图关注this tutorial，并且在字典和模型遇到很多问题后会在启动时崩溃，例如。

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

我加载了this dictionary并获得了their SourceForge page

中的语言和声学模型

然后崩溃了：

这是我的代码。

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();
        }
    }
}

正确的字典不应该有压力标记，你可以从这里下载：

startRecognition中的sphinx-4 NullPointerException
