[SRILM User List] nbest rescoring for LM with different smoothing

[Md. Akmal Haidar]

Hi,

Using -no-expansion option in the lattice-tool command, I got the different result.

Thanks
Best Regards
Akmal

Do the LM probabilities differ in the details?  (Compare the rescored nbest lists.)

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.
