我使用下面的語法：獅身人面像使用JSGF語法與重量：顯示java.lang.NullPointerException異常
#JSGF V1.0;
grammar tag;
public <tag> = <tagPart> +;
<tagPart> = <digit> | <letter>;
<digit> = oh | zero | one | two | three | four | five | six |seven | eight | nine ;
<letter> = a | b | c | d | e | f | g | h | i | j | k | l | m | n | o | p | q | r | s | t | u | v | w | x | y | z ;
一切運作良好，除非我添加砝碼。配重塊運行：
<tagPart> = /0.8/ <digit> | /0.1/ <letter>;
我收到以下錯誤：
Exception in thread "main" java.lang.NullPointerException
at edu.cmu.sphinx.jsgf.JSGFGrammar.getNormalizedWeights(JSGFGrammar.java:49)
我使用語法的方法是：
Configuration configuration = new Configuration();
configuration.setAcousticModelPath("file:/E/sphinx4-5prealpha-src/sphinx4-data/src/main/resources/edu/cmu/sphinx/models/en-us/en-us");
configuration.setDictionaryPath("file:/E/sphinx4-5prealpha-src/sphinx4-data/src/main/resources/edu/cmu/sphinx/models/en-us/cmudict-en-us.dict");
configuration.setGrammarPath("file:/E/sT/src/main/resources/");
configuration.setGrammarName("tag");
configuration.setUseGrammar(true);
StreamSpeechRecognizer recognizer = new StreamSpeechRecognizer(configuration);
