[hts-users:03047] Increasing the no. of statea


Dear all,
 
What I need to do if I want to increase the no. of states, e.g. from 5 to 12? Is changing $nState in Config.pm the only step required?
 
or do I need to change the no. of streams in HShell.h, as shown in [hts-users:01330]?
 
I have changed $nState previously from 5 to 12, but the training process stopped during embedded re-estimation (clustered) with the error message below:
 
...

Similar errors occur, even if I changed the no. of states from 5 to 7. I am using HTS2.1.1 and there is no warning before embedded re-estimation (clustered). The no. of streams is 6.

Please help. Thank you very much.
