Recognizing single characters into java using voice recognition

Is there any implementation in java to capture only characters? Will CMU Sphinx be able to do this? I've been trying with no luck at all. For a fact google speech API does a very poor job out of this. Characters like B,W,X are recognized but almost all the vowels are not! Any information is appreciated. Thanks!

Write grammar letters.gram like this:

#JSGF V1.0;

grammar letters;

public <letter> = (a. | b. | c. | d. | e. | f. | j.) *;

Use it sphinx4 like this:

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.setGrammarPath("file:grammars_folder");
configuration.setGrammarName("letters");
configuration.setUseGrammar(true);

LiveSpeechRecognizer recognizer = new LiveSpeechRecognizer(configuration);
recognizer.startRecognition(true);
SpeechResult result = recognizer.getResult();
recognizer.stopRecognition();
