adapting an acoustic model

[lloyd89]

hi i had adapted the acoustic model earlier in ubuntu 9.10 but due to some
reasons the folder 'adapt' got deleted.now i'm trying to adapt it again in
ubuntu 10.10,but when i enter

for i in seq 1 20; do
fn=printf arctic_%04d $i;
read sent; echo $sent;
rec -r 16000 -e signed-integer -b 16 -c 1 $fn.wav 2>/dev/null;
done < arctic20.txt

the 20 sentences are displayed in the terminal window continuously whereas
earlier they used to appear 1 at a time and after the recording was over ,ctrl
c was to b pressed.

can u advice wat is the problem.

[Nickolay V. Shmyrev]

The issue is that 'rec' application can't record audio. That's because you
don't have oss compatibility layer installed probably. You can try to run
'rec' manually to see what's the difference. Also you can blame Ubuntu
developers for breaking backward capabilities for such a simple applications.

[lloyd89]

thanks 4 replying.can you tell me how to run rec manually in the command line.
also wanted to know will this cause any problems in adapting the acoustic
model.

[Nickolay V. Shmyrev]

Open the terminal and type

 rec -r 16000 -e signed-integer -b 16 -c 1 out.wav

Read the output

thanks for that.

what could be the problem

[Nickolay V. Shmyrev]

what could be the problem

The problem is that you are not careful enough and do not read what is written
for you

[lloyd89]

i have recorded the wave files and completed the adaptation as given in the
cmu.wiki 'adapting an acoustic model' up till the part where i we need to
Convert the sendump and mdef files.when i proceed further with:

/bw -hmmdir hub4wsj_sc_8k -moddeffn hub4wsj_sc_8k/mdef.txt -ts2cbfn .semi.
-feat 1s_c_d_dd -svspec 0-12/13-25/26-38 -cmn current -agc none -dictfn
arctic20.dic -ctlfn arctic20.fileids -lsnfn arctic20.transcription -accumdir

i get the error :

FATAL_ERROR: "corpus.c", line 1647: Failed to get the files after 100 retries
of getting MFCC(about 300 seconds)

[Nickolay V. Shmyrev]

Right, that's because you incorrectly specified the path in fileids file. Your
fileids file has windows-style newline which is not allowed.

Application told you that, tuturial also stress that. You just need to read
the tutorial carefully and do what it does.
