You're likely using pocketsphinx8-5prealpha. There are some API changes, as detailed in this message from the support forum ERROR:root:Error occured! init() got an unexpected keywork argument 'hmm'. For reference's sake, here's the changes I have in my (working with 5prealpha) stt.py

do not use TAB while indent a line in profile.yml, instead use two SPACE and see if that solve your issue.
from jasper-client.
I tried exactly two spaces for indenting, but that caused the crash as before. My profile.yml:
carrier: ''

phone_number: ''

(I used two spaces to start the hmmdir line, githubs formatting just isnt showing it)

See configuration here

And validate your yaml here

Oh shoot ok I see the issue with the indenting, thats fixed now
from jasper-client.
I reverted the changed path that I tried to change by hardcoding in client/stt.py, but jasper still crashes:

Im not clear on what the issue is, but I wonder if the fact that the new path to the hmm dir does not contain a folder named hmm in its path might be throwing something off? FWIW, when I ls the directory that Im setting hmm_dir to, the output is
usr@server:/usr/share/pocketsphinx/model/en-us/en-us$ ls
feat.params mdef means noisedict README sendump transition_matrices variances
Which is what should be in the hmm dir afaik
from jasper-client.
I double checked with a fresh clone of jasper and the crash still happens. The issue seems to be between Jasper and possibly the new directory location for hmm_dir
from jasper-client.
I think you missed pocketsphinx:
see below config
stt_engine: sphinx
pocketsphinx:
hmm_dir: '/usr/share/pocketsphinx/model/en-us/en-us'
from jasper-client.
I dont think thats the issue, my current profile.yml is
carrier: ''
first_name: John
gmail_address: ########
gmail_password: ########
last_name: Lawson
phone_number: ''
prefers_email: true
stt_engine: sphinx

Hey mecparts, I gave the changes you described a try but Im still crashing. Im having a little bit of trouble following the changes you made, the last part generating that transcribed variable and returning it is supposed to go in the del function ?
from jasper-client.
When I ran jasper with the changes you described it crashes with

No, the last changes are in the transcribe function. Look at the line numbers in the @@ lines of the diff.
from jasper-client.
Replace the __init__ function in the PocketSphinxSTT class with this code:
def __init__(self, vocabulary, hmm_dir="/usr/local/share/" +
"pocketsphinx/model/hmm/en_US/hub4wsj_sc_8k"):
"""
Initiates the pocketsphinx instance.
Arguments:
vocabulary -- a PocketsphinxVocabulary instance
hmm_dir -- the path of the Hidden Markov Model (HMM)
"""

# quirky bug where first import doesn't work

self._logger.debug("Initializing PocketSphinx Decoder with hmm_dir " +

if not os.path.exists(hmm_dir):
msg = ("hmm_dir '%s' does not exist! Please make sure that you " +
"have set the correct hmm_dir in your profile.") % hmm_dir
self._logger.error(msg)
raise RuntimeError(msg)

psConfig.set_string('-hmm', hmm_dir)
psConfig.set_string('-lm', vocabulary.decoder_kwargs['lm'])
psConfig.set_string('-dict', vocabulary.decoder_kwargs['dict'])
self._decoder = ps.Decoder(psConfig)
And the transcribe function in the same class with this:
def transcribe(self, fp):
"""
Performs STT, transcribing an audio file and returning the result.
Arguments:
fp -- a file object containing audio data
"""
fp.seek(44)
# FIXME: Can't use the Decoder.decode_raw() here, because
# pocketsphinx segfaults with tempfile.SpooledTemporaryFile()
data = fp.read()
self._decoder.start_utt()
self._decoder.process_raw(data, False, True)
self._decoder.end_utt()
#result = self._decoder.get_hyp()
result = self._decoder.hyp()
with open(self._logfile, 'r+') as f:
# for line in f:
# self._logger.debug(line.strip())
f.truncate()
#transcribed = [result[0]]
if result is None:
transcribed = []
else:
transcribed = [result[0]]
self._logger.info('Transcribed: %r', transcribed)
return transcribed
and see what that gets you. I can't guarantee it will work error free first time; I've modified the code I'm working with to return multiple hypotheses from PocketSphinx and to work with Mycroft's adapt.intent parser, among other things, so I can't really test it easily anymore. I like the fact that the adapt parser can assign probabilities to each hypothesis from PocketSphinx and that I can use those probabilities in the brain code to pick the best hypothesis to select a module (rather than Jasper's "use the first module that matches" approach).
from jasper-client.
this looks to be an issue caused by using an updated pocketsphinx version (from pip), rather than the outdated version that the Jasper docs and code rely on. is there any plan to make changes required to support the new version?

The work on Jasper - specifically making it work as-is and refactoring to Python 3 is being conducted at https://github.com/aplawson/jasper-client -- including a tutorial on how to build it and/or deploy it with a custom Raspbian ISO image. //adam
