I found this library that can be very interesting to make a plugin with it.
https://www.phpclasses.org/package/11383-PHP-Generate-form-inputs-to-allow-user-voice-control.html
This class can generate form inputs to allow user voice control.
It can generate HTML for form inputs that allow the user to set values of form inputs.
The class can generate form inputs with HTML tags that let the user set options of select inputs or set the value of text inputs according what the user said when the user touches on a microphone icon that appears on the Web page.
Currently it only works on the Chrome browser.
I have been working in a very large plugin for a few months different from everything in the store and I do not want to start a project if I have not finished the previous one, so I leave the link for you to comment if you see it interesting.
