You need to specify the compatible language model, you are using english model by default and that probably does not have any words from your dictionary.

I am trying to transcribe a wave file using the command:
pocketsphinx_continuous -infile infile.wav -hmm /root/sphinx-source/pt4/model_parameters/your_db.ci_cont -samprate 8000 -dict etc/your_db.dic
But get no transcription, only the following output:

I have already tried adding -cmninit 32.83,0.32,-0.61 to etc/feat.params as described here: https://sourceforge.net/p/cmusphinx/discussion/help/thread/399685e2/
Any ideas?
Thanks
You need to specify the compatible language model, you are using english model by default and that probably does not have any words from your dictionary.
