I'm training AM using 120 utterances and the length of each is about 2
minutes. There is about 60 utterances failed in training the CI models, and
the training process hangs at the module. I check the log files under
logdir/20.ci_hmm/, they are all in the same error "ERROR: "backward.c", line
431: final state not reached".
It shouldn't be senones problem because it's failed in training CI. I searched
online, and found it's possible caused by wrong transcript. But the
transcripts are all correct/match after I checked them. Could anyone tell
what's the possible reasons? How could I get the AM training continue? Really
appreciate.

Maybe your files have zero energy regions and because of that feature
extraction fails. There could be other issues caused by corrupted audio, noise
and so on.
Which SphinxTrain version are you using. How do you extract features.

Hi Nickolay, I was using the version built in March 2011 when I got the
problem. After I compiled the latest version from the trunk, the problem is
the same. I followed Wiki tutorial to extract features as following,

Share the model folder with me, I will take a look.

Hi
I was talking about whole training folder, it's not enough to see just models.
