Hi Vassil,

May I asked about the performance (in terms of WER/SER) of online decoder?

What is the expected WER for online-wav-gmm-decode-faster,
if I reached with  gmm-latgen-faster scores in table below?
I would like to use the same trained models for
online-wav-gmm-decode-faster as
I used for  gmm-latgen-faster (and lattice-best-path).

exp             RT coef         WER
_ri3b_fmmi_b    11.33336625     19.42
tri2b_mpe       1.2307175       21.22
mono            2.8952          49.88
tri3b_mmi       1.24198625      20.01
tri1            2.398165        28.13
tri2b_mmi       1.65662125      20.34
tri2a           2.15838         28.43
tri2b           1.451105        27.96
tri3b           1.0596075       27.79
tri3b_fmmi_c    11.4361875      19.13
tri2b_mmi_b0.05 2.0089575       19.64
tri3b_fmmi_d    16.1227625      19.5

The names and the core settings of experiments are the same as in
egs/voxforge/s5/run.sh

With the online-wav-gmm-decode-faster
I reached really bad scores due to bugs (which I still need to fix),
but still also in the online demo the results are not so nice.

Thanks for any help
