Add different language support

[Pierre-Gilles]

Hi !

I'm contacted you on Twitter last days, I'm the founder of Gladys.

I just finally tried your module with billing enabled on Google Cloud Plateform. It works like a charm :)

Just one feedback, as I'm speaking french, I want to send my voice to Google Cloud speech with the fr-FR languageCode.

We should be able to specify in your lib which language we are using. It's simple, just a little parameter to add :

    const recognitionStream = _self.recognizer.createRecognizeStream({
      config: {
        encoding: 'LINEAR16',
        sampleRate: 16000,
        languageCode: LANGUAGE_HERE
      },
      singleUtterance: true,
      interimResults: true,
      verbose: true
    })

Maybe it can be an optional parameter of the Sonus constructor.

It's just a detail, otherwise your module just works great :) Planning to make a blog post about that to my community.

If you want I can submit you a PR to add language support, or you can do it yourself, as you prefer.

Thanks again,

[Pierre-Gilles]

Another, non related feedback, when I install your module with a simple "npm install", post-install tasks of snowboy are not executed, and I don't get the compiled file of snowboy for my plateform ( and I get a missing file => /home/pi/node_modules/snowboy/lib/node/binding/Release/node-v48-linux-arm/snowboy.node )

But if I install manually snowboy after sonus, it just works.

Don't know if it's a problem on your side or on snowboy side :)

I already implemented that last night in #8 (see the updated example for usage). I haven't updated the npm package yet, there are a few more things I want to do first, but I'm hoping to sort those out tonight. Let me know if there's anything I can do to help with your blog post!

Interesting issue with the installation, haven't seen that before. I'll investigate!

Keep the feedback coming!

Closing this out because the language issue has been resolved and post-install seems to be working now.
