Take a picture or a screenshot with my voice

I spend a lot of time taking pictures with a usb camera attached to a microscope. Thing is... I need to manipulate the plaque with my two hands, so moving one hand from the microscope to the computer to take a screenshot (space bar) is really difficult. Question is... Is there an app that hears my voice and takes pictures? I was thinking ... maybe a personal voice assistant is the way to go... but maybe an application (like gnome-cheese or something) already does the job.... My question is a bit like this one (https://unix.stackexchange.com/questions/616291/detect-simple-voice-commands) . I have to say 'cheese' or 'photo' or 'whatever' and that's gonna be the input for whatever program can take screenshots... I've been searching around and found this https://voice2json.org/ . Somewhere it says that > It can be used to: > > Add voice commands to existing applications or Unix-style workflows I do not know if this is overkill or very simple. Ps. I am using Fedora 35 Thanks
