HInit -A -D -C hinit.conf -S de.hcompv.scp -M hmm0 -H proto -l hallo -L de/wav/ hallo

  ERROR [+2121]  HInit: Too Few Observation Sequences [1]
 FATAL ERROR - Terminating program HInit

You do not have enough data for training, you need to add more training data. Ideally you need at least 30 samples for each word.

Thank you for reply!!!

I realize that I have to speak/record 10 or more wav samples.
But I don't know, how de.hcompv.scp should be formated.

Here is a example line:
./de/mfc/hallo_0.mfc
...
./de/mfc/hallo_9.mfc

Thanks for helping
P.S.: you can follow my process on: http://dbase.center/data/speech/

here is the command, that I execute under Linux

HRest -A -D -T 1 -C ../config de.hcompv.scp -M hmm1 -H proto -l ich -L de/wav/ ich
