Re: n-best list generation using HTK

Sphinx 2/Sphinx 3/Sphinx 3.x available at:


Should not be that slow. There is a lot of documentation and scripts available for the Sphinxes and the Grand Janitor of sphinx, Arthur Chan, is very helpful in most cases..

For most setups Sphinx 2 is faster than 1x Real Time and definitely below 10x Real Time and should not be taking 1 hour for a sentence.. Is there something unique about your task ?

Hi all ..

    Could any one tell me how to generate n-best list using HTK? I have tried -n option of HVite for this. But I got the following errors.

ERROR [+3230]  Alignment using multiple tokens is not supported
ERROR [+5022]  GetChkedInt: Integer arg out of range in n option

    Then I have modified the code of HVite, such that it wont give this error. But finally, I am not able to get the n-best list. In the output.mlf I could see only one sentence. So, if this problem was faced by anyone before, please tell me how to fix this error.

    I am also trying Sphinx-2 decoder for this, but this is taking arnd 1 hr / sentence. Is there any other way to generate these nbest lists for rescoring?

    Please tell me if there is any other discussion forum related to the speech tools like HTK, Sphinx, Festival.etc.
