[hts-users:02524] AW: Slow issue about OpenFst in DemoScript

Hello,

How big are your fst-files (models/qst001/ver1/cmp/HFST/*.fst) ?
If they are bigger than 20 MB you might have a problem with the size of your cepstrum mgc file.

In the case you are using STRAIGHTV40_007c, you should change the command in /data/Makefile from
$(MGCEP) -a $(FREQWARP) -m $(MGCORDER) -l 1024 -j 0 -f 0.0 -q 3 > mgc/$${base}.mgc; \
to
$(MGCEP) -a $(FREQWARP) -m $(MGCORDER) -l 2048 -j 0 -f 0.0 -q 3 > mgc/$${base}.mgc; \

because STRAIGHTV40_007c uses a default frame size of 2048, so you could get errors when mcep is called with another frame size.

I haven't tried with STRAIGHTV40pcode, so if you use that version you might have to use another frame length.

On my machine the forced alignment takes 3,5 hours.

Good luck,

Florian

Betreff: [hts-users:02520] Slow issue about OpenFst in DemoScript

Hi,

I've run Demo Script for HTS-2.1.1 (HTS-demo_CMU_ARCTIC-SLT_STRAIGHT)

and I found a problem in sub-procedure of Training part which is,

$FALGN = 1; # forced alignment using WFST for no-silent GV

The problem is, these FALGN procedure is extreamly slow in my work-station.
(about 3~4 days passed since FALGN procedure was begined and it still
doing some process)

I've used same work-station for HTS related experiments since 4 month
ago and it was fast enough

to handle thouse kinds of simulations. So, I don't think it's about
hardware speed issue.
(That workstation is X86(32bit) based anyway)

Is that speed issues are normal? or there are some notices to be
mentioned related to OpenFst?

Hope to get some answer or clue about this.

Regard
