[Kaldi-developers] Adaptive Beam in decoder & gmm-aligened-compiled

[Saman M. <smo...@gm...>]

Hi everybody,
I have trained a model for alignment and I want to use that model for
aligning an audio file. Since my audio is long I decided to use Adaptive
Beam  in decoder. to do this I have changed decode_opts.min_active
and decode_opts.max_active for decoder. Now something strange happened. If
I do not set these parameters and I use beam=1000 (e.g.) the
gmm-aligned-compiled will success but by setting these parameters it fails.
I even set these parameters such that the adaptive beam will always be
greater than 1000 but still gmm-aligned-compiled  failed. why? and how can
I use adaptive beam for decoding?
Best
Saman
