Run on pi3 with minibian

[jaumard]

I'm trying to setup sonus on my pi 3 with minibian OS but doesn't work, I made a very small script who do:

const Sonus = require('sonus')
const speech = require('@google-cloud/speech')({
  projectId: 'projectID',
  keyFilename: './project-e522...efac7.json'
})

const hotwords = [{ file: './Hey_lisa.pmdl', hotword: 'hey lisa' }]
const language = 'fr-FR'
const sonus = Sonus.init({ hotwords, language }, speech)
Sonus.start(sonus)
sonus.on('hotword', (index, keyword) => console.log("!"))
sonus.on('final-result', console.log)

On my mac this script works perfectly but on my pi 3 the script start and after 2 seconds just finish without an error message :(

Any idea ? I install like the doc say sudo apt-get install sox libsox-fmt-all

Also try this config for sonus as the doc say:

const sonus = Sonus.init({ hotwords, language, recordProgram: 'arecord'}, speech)
//or
const sonus = Sonus.init({ hotwords, language, recordProgram: 'arecord', device: 'plughw:1,0' }, speech)
//or 
const sonus = Sonus.init({ hotwords, language, recordProgram: 'arecord', device: 'hw:1,0' }, speech)

All same result, script end after few seconds without any error message :(

It's possible that minibian isn't supported by snowboy. You might try running it standalone to see if the error is firing silently. What version of Node are you using?

You may need to re-build the module since it's compiled for a full version of raspbian (worst case you'll see what you're missing). Install build deps:

sudo apt-get install libatlas-base-dev

And then build the module from scratch when installing

npm install --fallback-to-build

I use node v7.9.0 I just try npm install --fallback-to-build but no problem :( but same result

I also try snowboy directly by following this http://docs.kitt.ai/snowboy/ and first I have this error rec FAIL formats: can't open input default': snd_pcm_open error: No such file or directory but once I first do export AUDIODEV=hw:1,0 then rec temp.wav work correctly so I try again my little sample but same result it just start and finish after 1/2 seconds

I tried to run the snowboy demo but I have those errors:

python demo.py Hey_lisa.pmdl 
Traceback (most recent call last):
  File "demo.py", line 1, in <module>
    import snowboydecoder
  File "/var/www/sonus/rpi-arm-raspbian-8.0-1.2.0/snowboydecoder.py", line 5, in <module>
    import snowboydetect

    __import__(name)
ImportError: libpython2.7.so.1.0: cannot open shared object file: No such file or directory

Not familiar enough why python to know what it means and fix it...

Ok it was just python-dev to install ^^ the demo is working great... but still not sonus :(

[jaumard]

Ok I made the hotword working by doing export LD_LIBRARY_PATH=/usr/local/lib/python2.7/ but now another error with google speech :(

export LD_LIBRARY_PATH=/usr/local/lib/python2.7/
node index.js

Any idea ?

This should be fixed in the latest commit in master. I'll be updating the npm package later today.
