sphinx-4 NullPointerException在startRecognition [英] sphinx-4 NullPointerException at startRecognition
问题描述
我正在尝试遵循本教程，它在启动后由于很多原因而崩溃字典和模型出现问题，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
我加载了这本词典，从其SourceForge页中获得了语言和声学模型.
然后它崩溃了:

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();
}
}
}
正确的字典不应带有压力标记，您可以从此处下载:

I'm trying to follow this tutorial, and it crashes upon startup after having lots of problems with the dictionary and models, such as.
The dictionary is missing a phonetic transcription for the word 'humphrey'
and

SEVERE: Missing HMM for unit T with lc=N rc=EH1
13:14:50.601 SEVERE lexTreeLinguist Bad HMM Unit: EH1
I loaded this dictionary and got the language and acoustic models from their SourceForge page
It then crashes with this:

The correct dictionary should not have stress marks, you can download it from here:
