NA

Additional context

Needs to be tested with electron DEP, by trying switching to

npm install pocketsphinx-stt@3.0.0-alpha.1

and running npm run start:prod etc..

as separate issue worth looking into same segmentation and Multithread to speed up Mozilla DeepSpeech STT

So unfortunately no worker threads in electron yet. I have been using the cluster api instead until this feature is no longer experimental.
https://nodejs.org/dist/latest-v10.x/docs/api/cluster.html
I have example code here https://github.com/vijayee/js-offs/blob/master/src/block-cache-cluster.js
vs its worker counterpart https://github.com/vijayee/js-offs/blob/master/src/block-cache-worker.js

seems like it's not compatible for now, so closing for now to revisit if this ever changes, or if there's time to refactor using cluster.
