At script directory in HTS-demo_CMU-ARCTIC-AWB.tar.gz which is 
distributed in the HTS web site, you can find mkdata.in (or mkdata.pl).
This script is designed to prepare training data from waveforms.


In this script, you can find

perl $scpdir/delta.pl $mcepdim $mcepdir/${base}.mcep @mcepwin > 
$cmpdir/tmp.mcep

This script reads regression window coefficients, computes dynamic 
features, and outputs results.
So please run this script with your input/output mcep filenames as follows:

perl scripts/delta.pl 25 aaaaaa.mcep win/mcep_dyn.win win/mcep_acc.win > 
aaaaa.mcep_dyn_acc


You can also find following lines in the mkdata.in (or mkdata.pl).

@STAT = stat "$cmpdir/tmp.cmp";
$size = $STAT[7]/$byte;
system "echo $size ".($frameshift * 10000000)." | $SPTKdir/x2x +al  > 
$cmpdir/tmp.head";
system "echo $byte 9 | $SPTKdir/x2x +as >> $cmpdir/tmp.head"
system "cat $cmpdir/tmp.head $cmpdir/tmp.cmp > $cmpdir/${base}.cmp";

In these lines, HTK header is prepared and concatenated to the training 
data.
By using them, you can attach HTK header to your own data.
