Ok, Girder maybe don't have voice recognition implementer yet, but at least we can find a way to patch it.
the way I managed to have vocal command is using MS sidewinder game voice.
it's a soft intended to help gamers by leaving the possibility to set verbal command to a keyboard equivilent.
Girder can catch those keyboard commands with the standard keyboard or KeyboardEx.
just map vocal commands to unused keys and catch em into girder to have vocal response to you media.
Mine answers to "skip track" or "exit program" on an enjoyable manner.
Ok I had to rethink most of my GML, but it's not as hard as it would be translating my GVMS to LUA
