This is a one-time userscript that provides only Google's server-side speech recognition as a polyfill, no further updates will be implemented. Use the (firefox-only) extension listed here for a better experience: https://github.com/apersongithub/Speech-Recognition-Polyfill

This is basically equivalent to Google Chrome's native support for the Web Speech API.
This userscript is the exact same speech recognition polyfill for voice search as on google.com and youtube.com. Remember to speak loud and clear.
Punctuation and grammar is only supported with with cloud v2 backend (see script for info).
This usersript may cause issues with sites that have their own polyfill implementation for unsupported browsers (unlikely).
The image below is of the actual extension but it works practically the same minus the customization options.
Please read the disclaimer in the script, basically as long as you use it like a normal person then you'll be good!
