问题
Trying edu.cmu.sphinx.pocketsphinx with processRaw to detect silence.
Using the following config:
en-us.lm.bin language model
en-us-ptm acoustic model
cmudict-en-us.dict dictionary
also setting remove_noise to True and samprate to 8000
I want to do a Ngram Search.
When the While loop calling processRaw finishes I call both
hypothesis.getHypstr() and
decoder.getInSpeech()
Why does getHypstr returns empty but getInSpeech returns True while actually there is no speech in the input argument given to processRaw.
Thanks.

En-us-ptm is 16khz model, it will not work with sample rate 8000. This causes bad results from hypstr.
If getInSpeech returns true it probably means there was a small noise the system accepted as speech.
