[clarification] The offline kaldi decode with MBR method confidence and the VOSK output confidence score is different..

We have tried the following sequence of commands to get the MBR decode using Kaldi offline(not the Kaldi fork from alphacep).

Method 1:
```
lattice-to-ctm-conf --inv-acoustic-scale=12 --decode-mbr=true "ark:gunzip -c exp/MF/model/chain/tdnn_1g_aug/MF/lat.1.gz|" - | utils/int2sym.pl -f 5 data_hindi_rnnlm_combined_text/lang/words.txt > 1.ctm
```

Method 2:
```
lattice-align-words data_hindi_rnnlm_MF/lang/phones/word_boundary.int exp/MF/model/chain/tdnn_1g_aug/final.mdl "ark:gunzip -c exp/MF/model/chain/tdnn_1g_aug/MF/lat.1.gz|" ark:- | lattice-to-ctm-conf ark:- - | utils/int2sym.pl -f 5 data_hindi_rnnlm_combined_text/lang/words.txt > 1.ctm
```

In both cases, the confidence score obtained from VOSK and Kaldi is different. Is VOSK doing any extra operations on top of the normal Kaldi output?
