you need to pick your build
then click the "task" link in the bottom left
then in the new page, click on tha "artifatcs" tab
then pick target.zip or target.dmg
that's your firefox build
extract, run with "./firefox -no-remote -profileManager"
create a profile named "webspeechapi"
close
run with "./firefox -no-remote -P webspeechapi"
once opened, go to about:config, search for webspeech.recognition, toggle both prefs to true
then go to about:deepspeech
click "install lib", wait for the download & extraction to complete
you should then get a reload, and be able to click "install en-us"
wait again for download & extraction, it should reload another time, and you should see some model parameters as well as "English (US)"
then you can go to, for example, translate.google.com
you will have a mic in the bottom left of the input box once you select "English" as an input language
please keep that to you
this is **very** preliminary code
I don't have to have people playing with it
at least not outside of my knowledge
