I think we are going to have fun with silence in this framework. If you have a look at the example alignment (after only 4 iterations over only 100 files) you can see a nice pattern in the silence s86->s83->s86 etc. However in the speech (Computers) the s83 state is appearing again for completely different bits of waveform.

I was thinking maybe we will need to bootstrap a silence model in some way.

Another problem is that during training I get these sort of messages:

WARNING [-2326] UpdateTrans : Model 1[b]: no transitions out of state 16 in HERest

WARNING [-2330] UpdateVars : Model 1[b]: no use of variance 16.1.1 in HERest

WARNING [-2330] UpdateMeans : Model 1[b]: no use of mean 16.1.1 in HERest

etc. I assume we are losing states. If you keep running HERest it after aboiut 9 iterations the whole thing pretty much implodes.
