CMU Sphinix is toooo Slow for recognizing live speech.I don't know if you have any idea for boost it?
This is my configuration:
configuration.setAcousticModelPath("WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz");
configuration.setDictionaryPath("cmudict.0.6d");
configuration.setLanguageModelPath("en-us.lm.dmp");
We are currently working on speedup, but for now sphinx4 is not realtime for large vocabulary. It's actually not a trivial task.
If you want a fast and not very accurate transcription you can edit default.config.xml in sphinx4 sources and recompile:
<property name="absoluteBeamWidth" value="10000"/>
<property name="relativeBeamWidth" value="1e-60"/>
<property name="absoluteWordBeamWidth" value="50"/>
<property name="relativeWordBeamWidth" value="1e-40"/>
Then it will work realtime.
