Using the -S option with HTK tools

[Anonymous Student]

What does -S do in HTK? I know it’s for passing a “script” file, but I don’t understand what that means or what format a script file should be in.

a script file (e.g., it might be called train.scp) would look something like this – a list of MFCC files with full paths:

/Volumes/Network/courses/sp/data/mfcc/train/s1764494_train.mfcc
/Volumes/Network/courses/sp/data/mfcc/train/s1766810_train.mfcc
/Volumes/Network/courses/sp/data/mfcc/train/s1770642_train.mfcc

You pass this using the -S flag like this

HRest ...other command line args here... \
      -S train.scp \
      models/hmm0/$WORD

noting that when you use -S you no longer pass any MFCC files as command line arguments.

But how do I make train.scp? Do I have to write it by hand?

[Simon]

At first, yes, make it by hand so you get the format right.

Eventually, you’ll want to make it from a list of USER names. The forum on shell scripting has some tips on how you might do this using a for loop that reads the USER list from one file and creates an HTK script in another file.
