[Kaldi-developers] help regarding Kaldi hmm topology

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

Hi,

I want to run Aurora 2.0 experiments with Kaldi.  For that I need to model
18 state hmm for digits. and 5 state hmm for silence and 3 state hmm for
short pause (between two consecutive digits).

My question is:
a) How we tie/share a state among different hmm models.

b) I want to use iterative training, therefore will have to manipulate hmm
in the middle of training for adding states for short pause and silence and
increasing Gaussian mixtures per state, so How
we modify hmm during the middle of training. In HTK we use HHED module to
do this.

Any help or reference material would be highly appreciated.


Best regards,
Arif
