@GitPiyush

• Yes, you should use 8kHz for hub4. you can set outputSampleRate: 8000 in your config, when initializing the recorder.
• I looked a little bit and can't tell what's wrong yet. How did you train your language model? I tried with hub4 language model, and the output made more sense to me.
• I don't think hub4 is a good acoustic model, I would recommend to build one on RM1 as explained on sphinx tutorial (but with more senones, like 1000), or the voxforge models.
• I recently documented how to split your JavaScript file into several smaller files containing the acoustic and language models. It should be useful to you as your pocketspinx.js is becoming very large.

Thanks for your response @syl22-00 .
i have created my language model and dictionary using weblink http://www.speech.cs.cmu.edu/tools/lmtool-new.html.
i used rm1_200(default) AM and included my LM and dictionary also but getting same issue. Problem is even if you not speak a single word, hyp is continuously printing words like - ICE NO ALL etc.
Please let me know if you can provide a good AM location.
the main reason why i am in doubt, the same shared AM and LM are working perfect with pocketsphinx desktop application. Is there any problem with generated javascript file.

@GitPiyush Your language model is not in the right format. It is in ARPA format and must be converted to CMU's binary format: sphinx_lm_convert -i ECL_Vocab.lm -o ECL_Vocab.DMP. Please refer to the language model documentation of CMUSphinx: http://cmusphinx.sourceforge.net/wiki/tutoriallm

After I converted your file, recognition was actually pretty good with the default RM1 model. I haven't tried with hub4.
