    Hello!

    I'm new to CMU Sphinx Recognizer, I have tried PocketSphinx_Bath and it works fine for me. However, I was wondering if there is some predefined Confidence rate threshold that can be set so that if the recording contained words other than the ones in the Dictionary provided and the confidence level in detection of these words was less than that specified threshold, these extra words won't be listed in the recognized ones in the output file.

    Please guide me on this matter as this will determine if I'll be using PocketSphinx_Batch in my application or not!

    pocketsphinx can return sentence hypotheses with per-word confidence. The
    easiest thing to do would be to examine these values at the next stage of
    the app and decide whether or not to accept an input word. The threshold is
    typically something you'd want to decide on in a broader context (for
    example with respect to an expected input).
