Name

mkbinhmm — convert HMM definition file in HTK ascii format to Julius binary format

Synopsis

mkbinhmm [-htkconf HTKConfigFile] {hmmdefs_file} {binhmm_file}

Description

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.

Options

-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.

EXAMPLES

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
