\n\
Increase the number of mixture of a continuous HMM.  Notice that option \n\
-ninc actually means the number of mixture one wants to split from the \n\
 original models. For example, if you have already 8 mixture and you \n\
 want to go to 16, then 8 should be specified.  \n\
\n\
Usually, the number of mixture is a power of two.  You are also \n\
recommended to split the number of mixture from 1 -> 2 -> 4 -> 8 \n\
-> and so on. \n\
