Hi,

I'm trying to perform silence removal on utterances using htk but I keep getting errors.I tried using HCopy with the silence parameters in the config file.

Can someone help me with this?

ok..so the parameters I used are as follows

SOURCEKIND = WAVEFORM
TARGETKIND = WAVEFORM
USESILDET = T
MEASURESIL = T

and I said

HCopy -C config src.wav targt.wav

am I missing something?

HTK only applies the silence detector if you extract features (do a framing processing).  Silence detector is disabled when you copy from wav to wav, this way you can only chop the files.

 So from what you are saying if I am going from SOURCEFORMAT=NIST to TARGETKIND=MFCC_0 and have USESILDET=T silence detection/removal should occur?

My configuration is as follows:

SOURCEFORMAT = NIST

TARGETKIND = MFCC_0

TARGETRATE = 100000.0

WINDOWSIZE = 250000.0

USEHAMMING = T

PREEMCOEF = 0.97

NUMCHANS = 26

CEPLIFTER = 22

NUMCEPS = 12

ENORMALISE = F

USESILDET = T

MEASURESIL = T

OUTSILWARN = T

However, when I run HCopy I get the same output as I do when I run HCopy with the same configuration file minus the last three lines (USESILDET, MEASURESIL, OUTSILWARN).

Thoughts?
