Lattice / nbest output

[Vitor Enes]

I can't seem to get the -outlatdir and -nbestdir switches to "work" when
invoked from command line with pocketsphinx_continuous (I'm using v0.6x
still... hopefully that is not the problem).

I am invoking using a line like these ones:

pocketsphinx_continuous -hmm ./amodeldir/ -lm ./lmdir/ -dict ./dictdir
-nbestdir ./nbestdir/ -nbest 10

pocketsphinx_continuous -hmm ./amodeldir/ -lm ./lmdir/ -dict ./dictdir
-outlatdir ./lattice

Neither of those create anything at all (both directories already exist).

Are those switches disabled now? Maybe I should ask: can I get not just ONE
recognition "return" but, say, the "best" 3 options the ASR came up with?

Thanks in advance for any help. Will be greatly appreciated, since (as you
surely noted) I am a total noob in these matters.

vitorenes,

Are you attempting to obtain the "best" n hypotheses for a given utterance? If
so, I am in need of doing the same thing. I don't want to ask a duplicate
question. I'll monitor this question and can help out (try things on my end)
if need be.

Thanks.

That's exactly it. Any help will be greatly appreciated - I'll post any
findings here as well.

Cheers.

They are not supposed to. -nbestdir is an option for pocketsphinx_batch, not
pocketsphinx_continuous

Yes, you can, you can write your own tool using pocketsphinx API.

Look at pocketsphinx.c :

for (seg = ps_seg_iter(ps, &score); seg;
seg = ps_seg_next(seg)) {
char const *word;
int sf, ef;
int32 post, lscr, ascr, lback;

word = ps_seg_word(seg);
ps_seg_frames(seg, &sf, &ef);
post = ps_seg_prob(seg, &ascr, &lscr, &lback);
E_INFO_NOFN("%-20s %-5d %-5d %-1.3f %-10d %-10d %-3d\n",
word, sf, ef, logmath_exp(ps_get_logmath(ps), post), ascr, lscr, lback);
}
that's almost done ;)
