Dictation mics are not cheap, unfortunately, but you may be able to get used ones for much less.

*Quick guide to save you time:

-you can say "scroll to top/bottom", "click ok", "open Firefox", etc.

-it will always be typing when you talk unless it a) hears a command, b) you say "command mode", which will listen only for commands, or c) you mute:

-"mute" puts mic to sleep so you don't accidentally type when speaking ("unmute" to unmute)

-say "what can I say" to open advanced menu, allowing you to setup custom voice commands ("open projects folder", "open xyz website", etc.). Works well!

-full voice control of mouse is possible but a little slow. "Open grid" splits screen into a numbered 3x3 grid. You pick a number, it creates a new 3x3 grid in side the box you chose, and repeat until you can tell it to click.

The other thing I tried on Android is Futo voice input via F-droid + an app that turns you phone into a bluetooth keyboard (so as I spoke, it "typed" on the target device). The keyboard app is "Bluetooth Keyboard & Mouse"). It worked smoothly sometimes and other times not.

I map one of the keys to voice input push-to-talk for handy: https://handy.computer/

This involved reverse engineering and writing new drivers for both (with no existing reference for the PSVR). It's all in that library, so if that sounds interesting to you, you can probably get Claude/Codex/whatever to convert it to a Windows app pretty quickly.

I haven't been maintaining this tool actively, but maybe it's useful to someone.

A MX3 air mouse might be the exact thing you want though.

I don't know if any of them have PTT with microphone but you should be able to pair the clicker with a regular bluetooth headset, while the headset may be on all the time you might be able to use something like joy-2-key and a macro/hotkey utility to map the button press to mic mute.
