Yes

No, there is only cmninit parameter you need to adjust if you are using live mode.

dimention is 1,with batch mode no live mode.

I trained with it and with no any errors in my trainning.

But it's fatal errors when I decode it with sphinx3 .

And if I set cmn_arg with "none",as if decoder will no execu without cmn?

It's quite strange decision to use dimension 1. The usual feature dimension is from 15 to 50.

I want to use Sphinx3 with a different set of features, of size 80. I want to know whether Sphinx3 and SphinTrain support using these many features

Could you please specify how exactly one can use PLP features with Sphinx 3? 

I wish to train models using sphinxtrain. I found that sphinx_fe is designed exclusively for MFCCs. 

This table:

http://nshmyrev.blogspot.de/2011/07/decoders-and-features.html

testifies that PLPs are natively supported only by Sphinx 4. Should I extract them with HTK or so? What I have to specify then as $CFG_FEATURE in the config?
