void gms_free | ( | HMMWork * | wrk | ) |
Get HMM State probability of current state with Gaussiam Mixture Selection.
If the GMS HMM score of the corresponding basephone is below the N-best, the triphone score will not be computed, and the score of the GMS HMM will be returned instead as a fallback score. Else, the precise triphone will be computed and returned.
