PocketSphinx usage with wave

[Anonymous]

Hello,

I tried to use PocketSphinx on a pre-recorded wave file using the argument
list that I found in pocketsphinx_test and just appending the filename. But
that didn't work out (obviously). Can someone tell me what parts I got wrong
and need to change?

1: Sphinx-4's 12345.wav; RIFF (little-endian) data, WAVE audio, Microsoft PCM,
16 bit, mono 16000 Hz
2: -adcin yes \
-ctl ${CTLFILE} \
-cepdir ${DATADIR} \
-cepext .16k \
-samprate 16000 \
-agc none \
-fwdflat no -bestpath no \
-lm ${TASK}/turtle.lm \
-dict ${TASK}/turtle.dic \
-hmm ${HMM} \
-mmap yes

What exactly have you done, its impossible to understand from it

But that didn't work out (obviously)

What was broken?

Please try to provide more precise and detailed information

You need to specify the length of the .wav header with the switch -adchdr 44.

@nshmyrev

command:

./pocketsphinx_batch \
    -adcin yes \
    -ctl ../share/pocketsphinx/model/lm/turtle/turtle.ctl \
    -samprate 16000 \
    -agc none \
    -fwdflat no \
    -bestpath no \
    -lm ../share/pocketsphinx/model/lm/turtle/turtle.lm \
    -dict ../share/pocketsphinx/model/lm/turtle/turtle.dic \
    -hmm ../share/pocketsphinx/model/hmm/wsj1 \
    -mmap yes \
    -adchdr 44 \
    ~/sphinx/12345.wav

output:
ERROR: "cmd_ln.c", line 559: Unknown argument name './pocketsphinx_batch'
ERROR: "cmd_ln.c", line 644: cmd_ln_parse_r failed

Looks like it is choking on argv?

And after some looking around I found the problem: pebkac. Thank you cbader
for the -adchdr hint.

K, thanks. This confusing warning was fixed in trunk.
