Some time ago I made a script manager(https://github.com/fxnoob/Hand-in-the-air) inspired by Alexa skills system. Where you invoke scripts with hand gestures or with your voice.
In chrome extension i'm using webSpeech api, which sends voice data to google server and get text back, but one doesnt have to login in any account to verify. SO in a way google gets your voice data but that data is sudo anonymous.
At the moment no,but its not that far, one has to write macros to replace words to special chars which simple means introducing a new command in the codebase which already has a good structure and structured in a way to support multiple languages.
I've started this project, so i could type in julia lang(in pluto notebook).
currently one could type text, emoji, and do some other stuff, which is defined in terms of commands
see full list of command in the readme of
