Re: [Kaldi-developers] GMM based model statistics

[Arif K. <ife...@gm...>]

Thanks Daniel for you quick answer.

I have another question. I train a model using the WSJ S1 and S5 recipe,
and got good results on monophone system than triphone. I have about 1000
utterances, with length of ~1 hr, and about 300 vocabulary size.

In theory,  the triphone system should perform better than monophone. So I
don't know if something is wrong in the tree construction or any thing else
could be fixed.

Best regards,
Arif
