I am try to running the example code bellow and getting error

INFO: feat.c(715): Initializing feature stream to type: '1s_c_d_dd', ceplen=13, CMN='live', VARNORM='no', AGC='none'
ERROR: "acmod.c", line 79: Folder 'pocketsphinx/model/en-us/en-us' does not contain acoustic model definition 'mdef'
Traceback (most recent call last):

  File "/usr/local/lib/python2.7/dist-packages/pocketsphinx/pocketsphinx.py", line 260, in __init__
    this = _pocketsphinx.new_Decoder(*args)
RuntimeError: new_Decoder returned -1

My Code:

#!/usr/bin/env python
from os import environ, path

from pocketsphinx.pocketsphinx import *
from sphinxbase.sphinxbase import *

MODELDIR = "pocketsphinx/model"
DATADIR = "pocketsphinx/test/data"

# Create a decoder with certain model
config = Decoder.default_config()
config.set_string('-hmm', path.join(MODELDIR, 'en-us/en-us'))
config.set_string('-lm', path.join(MODELDIR, 'en-us/en-us.lm.bin'))
config.set_string('-dict', path.join(MODELDIR, 'en-us/cmudict-en-us.dict'))
decoder = Decoder(config)

# Decode streaming data.
decoder = Decoder(config)
decoder.start_utt()
stream = open(path.join(DATADIR, 'goforward.raw'), 'rb')
while True:
  buf = stream.read(1024)
  if buf:
    decoder.process_raw(buf, False, False)
  else:
    break
decoder.end_utt()
print ('Best hypothesis segments: ', [seg.word for seg in decoder.seg()])

How can i solve this problem .

Thanks

I am facing the same error. I made changes to config file.

Hi, I've faced with same problem to. Just check the folders with installed pocketsphinx packages and verify if the MODELDIR and DATADIR path are correct and .set_string to.

In my case package were installed in this folder. /home/user-name/.pyenv/versions/general/lib/python3.6/site-packages/pocketsphinx/model. And there was no folder 'test' and nested 'en-us' folder.
