Updating/adapting acoustic models

[asr2010]

Hi folks,

I trained an acoustic model with 16 Gaussians using RunAll.pl script. Is there
a way to update it to 32 Gaussians instead of starting from scratch ?

I'd like to use MLLR transform in Sphinx4...does anyone has a solution for
that ?

Thanks in advance

Change value in etc/sphinx_train.cfg, then run

./scripts_pl/50.cd_hmm_tied/slave_convg.pl 32

You implement it yourself of pay to someone else to implement it.
