Can I repurpose a Bluetooth voice remote as input device for a PC?

I am exploring ways to work with my PC that doesnt involve always sitting at a desk and typing with hands like a cave man.

Testing out using Wispr Flow and similar voice inputs -- seems to work fine for some use cases.

I also place the laptop on a treadmill sometimes and try to to get some research / browsing / work done. Mouse (trackball) and typing are the current weakest link.

are there decent handheld input gadgets that allow simple trackpad / click / scroll up&down / next&previous type of navigation and a push-to-talk voice input? I am looking at cheap remotes for FireTV stick and other streaming boxes that seem to have voice input -- anyway one could hack one of those to do our bidding and pair with a PC?
