Hello everybody, my problem is the following : I have french acoustic models for sphinx3 and I try integrate them in pocketSphinx.

I already try pocket Sphinx with english acoustic model and there was no problem.

My command is :

pocketsphinx_batch \
    -adcin yes \
    -dict /home/pocket-sphinx/pocketsphinx-0.5-fr/DESDHIS-2_sphinx.dico \
    -hmm /home/pocket-sphinx/pocketsphinx-0.5-fr/bref120ci \
    -ctl /home/pocket-sphinx/pocketsphinx-0.5-fr/ca-fr.ctl \
    -cepext .raw \
    -cepdir /home/pocket-sphinx/pocketsphinx-0.5-fr/cepstra \
    -fdict /home/pocket-sphinx/pocketsphinx-0.5-fr/bref120.filler \
    -lm /home/pocket-sphinx/pocketsphinx-0.5-fr/DESDHIS-2-Interpole.sphinx.trigram.DMP \
    -wip 0.8 \
    -lw 12 \
    -hyp res.trn

And I have an error message :

If you have any suggestions , thank you very much.

 

PS : excuse me for english mistakes but I am French and I don't speak english very often.

thank you for your quick answer.

I have no longer the previous problem but I obviously a new problem :

For each word of my dictionnary, I have the following message :

 WARNING: "ngram_search_fwdtree.c", line 115: Filler word 202 = accompagne(2) has more than one phone, ignoring it.

Seemingly, Sphinx confuses the filler and the the dictionnary but I don't know why.

I am going to find an answer on the CMU Sphinx forum.

Bonjour,

Did you succeed to migrate the french sphinx3 acoustic model on pocketsphinx?

Regards,

Laurent

I'm wondering that i'm also facing same problem and adding the -dictbase 'yes' in etc/feat.params does not help me anymore. Would be greatful to get a reply.

Thank

I'm using lium files (http://www-lium.univ-lemans.fr/fr/content/ressources).

"means" file alway return an error by s2_semi_mgau.c :

 "s2_semi_mgau.c", line 1011: /home/tom/Public/sphinx/lium_acoustic_models/parameters/F2/means: #codebooks (5725) != 1

Ressources files provided are to be used with sphinx 3.x, are compatible with pocketsphinx ?

Hello. LIUM models are compatible with pocketsphinx. Please use latest pocketsphinx version to avoid issues like described. Pocketsphinx-0.7 works just fine


Please download french acoustic models from cmusphinx website, not from the old location. Our website contains all the models we have in a single location. Models are kept up-to-date.

Yes, thank you : ubuntu pocketsphinx version is quite old, sorry.

Is it possible to train pocketsphinx ? Does it lead to better results ?
