Success rate of a recognition

[darkingthereturn]

Hi!!!
Is there a way to get, through pocketsphinx, a sort of "success rate" or a
mark that indicates how much pocketsphinx "thinks" that the word decoded is
correct? I mean, pocketsphinx gives a mark in decoding audio? I would like to
know it because, considering the mark, i can establish if the audio decoded
it's rubbish or effectively a word!

Another question: I've got some float arrays where sound is sampled. Can i
pass directly the flot array to pockesphinx api(s) for recognition?

Thank you and sorry for my worst english.

This is called "confidence score" or "posterior probability". You can access
this value through API:

/**
 * Get posterior probability.
 *
 * @note Unless the -bestpath option is enabled, this function will
 * always return zero (corresponding to a posterior probability of
 * 1.0).  Even if -bestpath is enabled, it will also return zero when
 * called on a partial result.  Ongoing research into effective
 * confidence annotation for partial hypotheses may result in these
 * restrictions being lifted in future versions.
 *
 * @param ps Decoder.
 * @param out_uttid Output: utterance ID for this utterance.
 * @return Posterior probability of the best hypothesis.

int32 ps_get_prob(ps_decoder_t *ps, char const **out_uttid)

No, you need to convert the data to the array of shorts

I'm sorry for wrong section about this topic. So, for the array, i've got to
convert them in shorts. And then? What function will decode it? Thank you for
the ps_get_prob function!

And then?

Please read the tutorial

What function will decode it?
