CMU Sphinx / Forums / Help: -adcdev argument in Python script

Agathe Blaise - 2016-03-11

I'm trying to launch pocketsphinx with a mic.

So when I'm launching "pocketsphinx_continuous -hmm /usr/local/share/pocketsphinx/model/en-us/en-us -lm 9961.lm -dict 9961.dic -samprate 16000/8000/48000 -inmic yes -adcdev plughw:1,0", there are no problems.

But when I'm launching a script with pocketsphinx where I give some arguments to the decoder, it doesn't work.
Here is an extract of the code :

from pocketsphinx import * hmm = '/usr/local/share/pocketsphinx/model/en-us/en-us' dic = '/usr/local/share/pocketsphinx/model/en-us/9961.dic' lm= '/usr/local/share/pocketsphinx/model/en-us/9961.lm' config = Decoder.default_config() config.set_string('-hmm', hmm) config.set_string('-lm', lm) config.set_string('-dict', dic) config.set_string('-logfn', '/dev/null') config.set_string('-adcdev', 'plughw:1,0')

But it returns : ERROR: "cmd_ln.c", line 938: Unknown argument: -adcdev

Maybe I haven't the right syntax, I don't know.

  In python you configure adcdev in pyaudio framework which does the recording, not in pocketsphinx. You can use input_device_index option for that.

So I remove the line config.set_string('-adcdev', 'plughw:1,0').
Then I replace the line stream = p.open(format=pyaudio.paInt16, channels=1, rate=16000, input=True, frames_per_buffer=1024)
with stream = p.open(format=pyaudio.paInt16, channels=1, rate=16000, input=True, frames_per_buffer=1024, input_device_index=1)

But I still have some errors.

  You can enable logging back (-logfn option) to see the details.

It is saved in /dev/null, but I don't know how to open this file.

  /dev/null is a unix special file (device) to drop output. Everything written to that file is lost.
  
  You can remove the line
  
  config.set_string('-logfn', '/dev/null')
  
  to dump log to stdout. You can also use
  
  config.set_string('-logfn', 'filename.log')
  
  to dump log to a file.

Ok, thanks you.
So I could fix some erros, but I still have these ones :

I converted 9961.lm.bin into 9961.lm.bin and some errors are no longer here.
It seems like I have some problems with my cards

You need to configure alsa properly first, then start playing with pocketsphinx.

It didn't work on my Raspberry Pi, but on my laptop, when I'm launching my program with a stream related to the third micro like this :

stream = p.open(format=pyaudio.paInt16, channels=1, rate=16000, input=True, frames_per_buffer=1024, input_device_index = 3

I obtain these errors, which said that the number of channel (1 here) is incorrect.

  I don't think that index 3 is valid in your system, most likely you have different card layout. To get help on this issue you need to provide the alsa configuration. You can dump it with
  
  arecord -l
  
  you can also try to record from command line to make sure things work:
  
  arecord -D <device_name> -f S24_LE -c 1 -r 16000 test.wav

The result of arecord -l is :

**** List of CAPTURE Hardware Devices **** card 1: PCH [HDA Intel PCH], device 0: 92HD91BXX Analog [92HD91BXX Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 3: Device [USB Video Device], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0

So I'm launching arecord -D plughw;3,0, but index_option_device requires an integer.

  I guess you need to try other values of index like 1 or 2, don't you think so.

Yes, of course I already tried index between 0 and 3 but none of these work. I think the channel is the problem.

  Try with two channels?

With this piece of code found on https://doc.ubuntu-fr.org/pocketsphinx, I succeeded to list all the input devices index like this :

PortAudio System Info:

Here the index was 5.
Thanks you very much for your help, I'm very grateful to you.
