ERROR:root:Error occured! __init__() got an unexpected keywork argument 'hmm'

[Brent Hunter]

Hello all,

I've installed Jasper onto a RPi2 successfully, and all is working well (kind of) when integrating with Google STT/TTS.

However, I wanted to use CMUSphinx/Pocketsphinx for offline recognition.  I've reconfigured Jasper profile, and now I get the following when executing jasper.py:

root@raspberrypi:/home/pi/jasper# ./jasper.py --debug

After some time spent analysing the code in stt.py, I've discovered I needed to change the following code:

from:

 self._decoder = ps.Decoder(hmm=hmm_dir, logfn=self._logfile, **vocabulary.decoder_kwargs)
 

to:

        #self._decoder = ps.Decoder(logfn=self._logfile, hmm=hmm_dir, **vocabulary.decoder_kwargs)
 psConfig = ps.Decoder.default_config()
 psConfig.set_string('-hmm', hmm_dir)
 psConfig.set_string('-lm', '/home/pi/lmfiles/cmusphinx-5.0-en-us.lm.dmp')
 psConfig.set_string('-dict', '/home/pi/dictfiles/cmudict-0.7b.dict')
 self._decoder = ps.Decoder(psConfig)

I still haven't got it working properly yet...  Is it because I'm using Pocketsphinx 5prealpha, instead of sphinx 0.8?

[Brent Hunter]

It's finally working.  I'm not sure why I had to change some code, but my guess is because I'm using 5prealpha (instead of pocketsphinx 0.8).

Ignore my post above. 

In the 'stt.py' file I removed the following line:

self._decoder = ps.Decoder(logfn=self._logfile, hmm=hmm_dir, **vocabulary.decoder_kwargs)

and replaced with this:

 psConfig = ps.Decoder.default_config()
 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)

Within the same 'stt.py' file I also had to change:

result = self._decoder.get_hyp()

to:

result = self._decoder.hyp()

Also:

transcribed = [result[0]]

was changed to:

transcribed = (result.hypstr, '')

transcribed is expecting to return a list of phrase/s, which is why I had to return a blank string along with the actual phrase to the transcribed variable.  I don't know Python that well, so if anyone can tell me why I had to do this would be great.

Hi Brent

You post was most helpful, however I changed your last line to this:

        if result is None:

                transcribed = ''

        else:

                transcribed = result.hypstr

Which seems to work wonderfully well. It seemed that in somecases result would end up as a NoneType which would cause things to error out. What this does is check to see if result has anything in it, and pass on either an empty string, or the object 'hypstr'

[Wei]

following your post then get this error: OSError: Can't find command 'phonetisaurus-g2p'! Please check if Phonetisaurus is installed and in your $PATH.

by the way, what is the change of profile.yml?

Hello Wei, Compile and install Sphinxbase/Pocketsphinx from source.

Installing Sphinxbase/Pocketsphinx

DONT DO THIS

First, you need to install Pocketsphinx. If you’re using Debian Sid (unstable) or Jessie (testing), you can just do:

sudo apt-get update
sudo apt-get install pocketsphinx

FOLLOW THIS 

If you’re not using Debian Sid/Jessie, you need to compile and install them from source:

wget http://downloads.sourceforge.net/project/cmusphinx/sphinxbase/0.8/sphinxbase-0.8.tar.gz
tar -zxvf sphinxbase-0.8.tar.gz
cd ~/sphinxbase-0.8/
./configure --enable-fixed
make
sudo make install
wget http://downloads.sourceforge.net/project/cmusphinx/pocketsphinx/0.8/pocketsphinx-0.8.tar.gz
tar -zxvf pocketsphinx-0.8.tar.gz
cd ~/pocketsphinx-0.8/
./configure
make
sudo make install

[Wei]

Hi Jitendra,
I have installed pocketsphinx 0.5 and it works ok, this is business between Jasper and sphinx, i just don't know the configuration of it. And i didn't install openfst and other dependences. Is that ok?

[Jitendra]

Why you are using old version of pocketsphinx ? There is no harm in using pocketsphinx 0.8. with Jasper also follows the following step

Installing Phonetisaurus, m2m-aligner and MITLM

To use the Pocketsphinx STT engine, you also need to install MIT Language Modeling Toolkit, m2m-aligner and Phonetisaurus (and thus OpenFST).

DONT DO THIS

On Debian, you can install these from the experimental repository:

sudo su -c "echo 'deb http://ftp.debian.org/debian experimental main contrib non-free' > /etc/apt/sources.list.d/experimental.list"
sudo apt-get update
sudo apt-get -t experimental install phonetisaurus m2m-aligner mitlm

FOLLOW BELOW STEPS

If you’re not using Debian, perform these steps:

wget http://distfiles.macports.org/openfst/openfst-1.3.3.tar.gz
wget https://mitlm.googlecode.com/files/mitlm-0.4.1.tar.gz
wget https://m2m-aligner.googlecode.com/files/m2m-aligner-1.2.tar.gz
wget https://phonetisaurus.googlecode.com/files/phonetisaurus-0.7.8.tgz


Build and Install all of the above Manually. See the further steps at
http://jasperproject.github.io/documentation/installation/

[Wei]

I have try to install openfst for several times, and compiling always stuck, someone said we need modify memory switch of raspberry pi, I didn't try that, I don't know if it will work.

[Jitendra]

Oh yes that the problem with Swap space.

Increase the swap space before compilation and then compile openfst and
after succesfull compilation remove swap file and free the memory

see below set of commands

To resize swap space:

sudo nano /etc/dphys-swapfile

CONF_SWAPSIZE=250

 

sudo dphys-swapfile setup

sudo dphys-swapfile  swapon

ls -l /var/swap

sudo apt-get --purge clean

Free the Swap space 

sudo swapoff -a

sudo update-rc.d -f dphys-swapfile remove

sudo rm /var/swap

ls -l /var/swap

free -h

[Wei]

Jitendra, thanks for your help, finally openfst successfully installed, 

at last, I got the same error: __init__() got an unexpected keyword argument 'hmm'

I modify the stt.py follow this post, and Jasper can print what I said, but has no response of any command, even no beeps.

seems Jasper didn't execute the command.

I installed pocketsphinx 5 prealpha and also installed pocketsphinx 0.8, so I just get confused, which one is working now?

how to uninstall pocketsphinx 5 prealpha? maybe I should uninstall it and reinstall 0.8.

[John Evans]

These instructions also helped me as well as the ones below (or above) from secret. I followed all the instructions for arch linux but just couldn't get it to work. I'm still not quite there but at least I'm a step further.

Thanks
