[hts-users:02538] Utterance size problem

[ali azimizadeh <ali.azimizadeh@xxxxxxxxx>]

Hi,
I changed the  HTS_Demo for HTS 2.1.1 to make a hts voice in Persian with my dataset but there is a little problem. my system properties are:
CPU: Pentium 4 Dual core 2.26GHz
Ram: 4G
Swap: 15G
OS: CentOS 5.3
Most of my wav file size are big. its range is from 33k to 2M. the main problem occurs in "forced alignment using WFST for no-silent GV". 
when the raw file is less than 300k everything is OK. but when it is bigger than 300k, at first the memory is fulled and then swap goes to maximum size and CPU doesn't work more. 
Often, $gvfaldir/$base.tmp1.sym and $gvfaldir/$base.tmp2.fst are made by fstcompose. 
note that i can't spite the utterance files into shorter ones more than this. do you have any hint?
and also, do you think that if the Ram is upgraded ,for example, to 8G the problem is solved?

Regards,
-Ali
