<br>
I have found the same WER scoring result using the LM with two
different smoothing (additive/Witten-Bell). <br>
First I have created the HTK lattice using the LM. Then, I
used the lattice-tool to find the nbest-list. <br>
<br>
How the the two LM trained on the same text with different
smoothing give the same WER result?<br>
<br>
Thanks<br>
Best Regards<br>
Akmal<br>

Do the LM probabilities differ in the details? (Compare the
rescored nbest lists.)<br>
<br>
If so then it could just be that your data is such that the
smoothing method by itself does not make enough of a difference to
change the top hypothesis choice.<br>
