A physical button for voice-to-text

I use voice-to-text so much now that I'm starting to wonder if I need a dedicated physical button for it.

I already have a little one-handed keyboard for my left hand, which has been nice. But I'm imagining something even easier. Maybe a button attached to my hand? A ring? Something I can press without reaching for a keyboard.

I did some searching and found something called Flic, but it didn't exactly inspire a ton of confidence.

Has anyone else gone down this rabbit hole? What did you end up using?
