Detailed Description

Check existence of all possible triphone in HMMList.

Author:

Date:

Tue Feb 15 19:17:51 2005

These functions check whether all the possible triphones that may appear while recognition process is fully defined or mapped in HMM definition file and HMMList file.

Word dictionary is considered for the test. Only triphones that can appear as word-internal triphones and cross-word triphones on the given dictionary will be considered.
