[SRILM User List] Fw: nbest-error option

[Md. Akmal Haidar]

Hi,

Yes. The nbest lists are different.
Is there any lmw required in rescore-reweight. The original nbest list were generated from htk lattice. htk lattice were generated using language model scale factor 15. should i use this in the rescore weight.

Is is possible to compute the wer using nbest-lattice -wer option. The total err(sum of sub,ins,del)  for the original nbest list is greater than the total err of using nbest list obtained by the updated lm.

Thanks
Best Regards
Akmal

Compare the rescored and the original nbest lists.   Are they different ?   Make sure you specify the NEW nbest directory created by rescore-decipher as the input to rescore-reweight, not the original one.

You need to have the sclite binary in your executable search path.   Modify the PATH environment variable so you can just type "sclite" and find the executable.
