mkbinhmm — convert HMM definition file in HTK ascii format to Julius binary format
mkbinhmm
[-htkconf HTKConfigFile
] {hmmdefs_file} {binhmm_file}
mkbinhmm convert an HMM definition file in HTK ascii format into a binary HMM file for Julius. It will greatly speed up the launch process.
You can also embed acoustic analysis condition parameters needed for
recognition into the output file. To embed the parameters, specify
the HTK Config file you have used to extract acoustic features for
training the HMM by the optione "-htkconf
".
The embedded parameters in a binary HMM format will be loaded into Julius automatically, so you do not need to specify the acoustic feature options at run time. It will be convenient when you deliver an acoustic model.
You can also specify binary file as the input. This can be used to update the old binary format into new one, or to embed the config parameters into the already existing binary files. If the input binhmm already has acoustic analysis parameters embedded, they will be overridden by the specified values.
mkbinhmm can read gzipped file as input.
-htkconf
HTKConfigFile
HTK Config file you used at training time. If specified, the values are embedded to the output file.
hmmdefs_file
The source HMm definitino file in HTK ascii format or Julius binary format.
hmmdefs_file
Output file.
Convert HTK ascii format HMM definition file into Julius binary file:
%
mkbinhmm hmmdefs.ascii binhmm
Furthermore, embed acoustic feature parameters as specified by Config file
%
mkbinhmm -htkconf Config hmmdefs.ascii binhmm
Embed the acoustic parameters into an existing binary file
%
mkbingram -htkconf Config old_binhmm new_binhmm
