python example file continuous_test.py "error"

[loek]

I use the raspberry pi with jessie and I installed pocketsphinx with pip.
When I run the example file continuoes_test.py I get this error:
Can someone help me solve this problem.

Traceback (most recent call last):
  File "continuous_test.py", line 16, in <module>
    decoder = Decoder(config)
  File "/usr/local/lib/python2.7/dist-packages/pocketsphinx/pocketsphinx.py", line 271, in __init__
    this = _pocketsphinx.new_Decoder(*args)
RuntimeError: new_Decoder returned -1

Below is the script:

#!/usr/bin/python
from os import environ, path
from pocketsphinx.pocketsphinx import *
from sphinxbase.sphinxbase import *

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

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'))
config.set_string('-logfn', '/dev/null')
decoder = Decoder(config)
stream = open(path.join(DATADIR, 'goforward.raw'), 'rb')
#stream = open('10001-90210-01803.wav', 'rb')
in_speech_bf = False
decoder.start_utt()
while True:
    buf = stream.read(1024)
    if buf:
        decoder.process_raw(buf, False, False)
        if decoder.get_in_speech() != in_speech_bf:
            in_speech_bf = decoder.get_in_speech()
            if not in_speech_bf:
                decoder.end_utt()
                print 'Result:', decoder.hyp().hypstr
                decoder.start_utt()
    else:
        break
decoder.end_utt()

MODELDIR = "../../../model"

You didn't specify a path to the acoustic model properly here, you need to specify correct path:

config.set_string('-logfn', '/dev/null')

You can remove this line to get more details about the problem.

Thanks. The file continuoes_test.py is working now. With this test I can hear my voice in the speaker. But the other example files in the dir test are not working.
Do you know an example that pocketsphinx say someting in the speaker.
I mean python examples.
