Dear Mr. Long,

Thanks a lot.

About your email:

Do you mean use sphinx 3 like this command using LM.arpa?

decode -cepdir mfc -ctl file.ctl -hyp out.trn -dict file.dict
-fdict file.filler -lm LM.arpa -hmm HMMpath - test.log

can do that or need another parameter to support this command for arpa file?

what I did:

1. create LM using srilm order 3 gram2. add-dummy-bows   3. sort-lm 
4. testing LM in sphinx 3 as above.

but still I have the following problem:

LM is not a DMP file ..... lm_read_advance(LM.arpa, 9.500000e+00, 7.000000e-01, 7.000000e-01 74961 [Arbitrary Fmt], Weighted Apply) failed

Please tell me what is the problem here?

Thanks and best regards,

Hi Noor,

You don't have to convert the LM to DMP format. Sphinx3 can directly 
load ARPA LM in TXT format. But you will still need to run 
add-dummy-bows to add 0 to ngrams whose back-off weight is zero.

Sometimes, the bigrams or trigrams are not sorted in the same order as 
unigram, which may cause an error in Sphinx3. If that happens, you will 
need to re-sort ngrams in your LM.
