[Kaldi-users] Facing problem while increasing number-of-states for non-silence phones

[Firoj A. <fir...@gm...>]

Hi,
I am having problem while I increase number-of-states for non-silence
phones in decoding. Please see the error log below. It assert error while
decoding. I would appreciate your input.

Thanks in advance.
Regards
Firoj
