I'm less clear what the error is since it is happening on the far side of the subprocess call.
Pocketsphinx was failing for me, too. If you remove '-logfn', '/dev/null' from the parameters in line 37 of audiogrep.py, you will see the log from pocketsphinx.
Mine said this at first:
INFO: feat.c(713): Initializing feature stream to type: '1s_c_d_dd', ceplen=13, CMN='current', VARNORM='no', AGC='none'

ERROR: "acmod.c", line 85: Acoustic model definition is not specified neither with -mdef option nor with -hmm
I realized that the way I installed it (I'm on ubuntu and did apt-get install pocketsphinx-utils), might not have installed any kind of acoustic/language models. So I installed the package, pocketsphinx-hmm-en-hub4wsj, and then it complained about not setting anything with -hmm.
So I modified the line that sets the parameters to the pocketsphinx_continuous call, giving it the location of the language model:
transcript = subprocess.check_output(['pocketsphinx_continuous', '-infile', f, '-hmm', '/usr/share/sphinx-voxforge-en/hmm/voxforge_en_sphinx.cd_cont_3000', '-time', 'yes', '-vad_prespeech', str(pre), '-vad_postspeech', str(post)])
It still complained about a missing something or other, so I installed another package, pocketsphinx-lm-en-hub4.
Now it is analyzing happily and my computer fan is buzzing away. It's taking a while... hopefully nothing breaks! I also wonder if there was a more straightforward way of doing this...
Hey - thanks for letting me know about this - I've only tested it on a mac. I should add some instructions about installing it on Ubuntu.
Your comment was very helpful. I've removed where the subprocess pipes the logs to /dev/null but I'm still not quite able to get it to work.
The debian version of pocketsphinx-hmm-en-hub4wsj doesn't contain the file voxforge_en_sphinx.cd_cont_3000:
https://packages.debian.org/jessie/all/pocketsphinx-hmm-en-hub4wsj/filelist
I will dig into this more in the morning.
I got it running on ubuntu 14.04 after applying @YottaSecond’s suggestions. Caveat on 14.04: I needed to change ffmpeg to avconv, since avconv is the shipped alternative to ffmpeg in this version.
@jdittrich, have you successfully generated any mp3s? Supercut.mp3 keeps coming back as 0 bytes for me, even though the log shows a bunch of different areas that are being cut.
@YottaSecond No, only transcripts – avconv crashes while generating (so I get 0byte files, too).
@YottaSecond @jdittrich I'm having the same problem. It generates transcripts (which for the most part are single words on each line but with some very large unbroken sections) and indicates its adding bits into the supercut but this ends up being 0 bytes. Perhaps a new bug should be filed for this specifically?
@OisinMoran @jdittrich We're all using avconv, right? Maybe this will work properly if we actually switch to ffmpeg? Or maybe it's just a matter of getting the right arguments for avconv?
I was having trouble finding a repository for ffmpeg, though, and I'm wondering if I'll have to build that from source? Right now it seems like a lot of work to do in order to make Obama say silly things, but if I do make any progress I'll be sure to update!
future ubuntu 15.04 includes ffmpeg again. The rather active ubuntuusers.de-wiki suggests using ppa:jon-severinsson/ffmpeg if one needs it. If anybody tries ffmpeg on linux instead of avconv, let us know.
@YottaSecond I am using ffmpeg and got it from the ppa:jon-severinsson/ffmpeg that @jdittrich suggested. I'm doing this all on linux btw
@OisinMoran a new bug makes sense imho, otherwise it will be hard for maintainers to see what the actual issues are.
I am working on a docker image for audiogrep and I ran into some of these issues as well. It really helps to just run the pocketsphinx command directly and see what it throws - so far I came across missing the hmm and lm libs and now I am trying a file that is too big and I get this error http://sourceforge.net/p/cmusphinx/discussion/help/thread/f609780c/
Dockerfile for interests sake https://github.com/kevinhughes27/audiogrep-docker/blob/master/Dockerfile
@sethwoodworth If you install pocketsphinx from the pocketsphinx website rather than from the debian package manager it works. The version packaged in debian is 0.8-5, the current version is 4-5
