Description
from tpvelka's post:
[...] Second, the creation of a full triphone list by HDMan must be done every time new triphones appear in testing data and does not work for cross-word triphones (these are used e.g. in HDecode). My solution for this is simply to synthesize all possible triphones. With the monophone set used by VoxForge? acoustic models there is a total of 81315 triphones which translates to about 3.5MB of extra space for the HMM definitions (text form).
A full triphone list can be generated by the script full_list.prl which can be found in the directory samples/RMHTK/perl_scripts which comes with the HTK distribution.
The full triphone HMM generation can be done using HHEd:
Assume the all-triphone list is stored in file xwrd_full_list these are the commands to go into the script file (let's call it synthesize.hed):
LT "trees"
AU "xwrd_full_list"
CO "xwrdtiedlist"
HHEd is run wiht the following parameters:
HHed -T 1 -H hmmdefs -H macros -M hmm_synthesized synthesize.hed tiedlist
where hmm_synthesized is the directory to store the new files.
