CMU Sphinx does it: Phoneme Recognition (caveat emptor)

Hi Ken,

         Thank you for the previous reply. Back to the forced alignment tutorial, the aligned.out has the neagtive numbers as well. Could you please explain what do they specify? And also can they be discarded?

Thank you 

Hi Ken,

         I have found the answers in the HTK book. Thank you.

Hi cvani,

For others that may have the same problem as you, please post the section number in the HTK book that helped you resolve this problem,

thanks,

Ken

I found the answer in section 13.4, page 187 in the HTK Book.

Hi Ken,

          I followed your forced alignment tutorial and in the last step I got an error which is,

Could you tell me what may be the reason?

Thank you.

Hi Ken,

I found the sphinx a bit difficult to understand. Is it not possible to do a free alignment using HTK itself?

Thank you

Hi ken,

         I have been waiting for your reply about the error I got with HVite. I hope I get it soon.

Thank you.

what does the HTK book say about your error?

Hi Ken,

          I did not find any thing in the HTK book. I am not sure why has this error occurred yet. 

Thank you.
