VoiceAttack can be used to freely create arbitrary voice commands with pretty good recognition accuracy. It can send KB&M or gamepad inputs and run scripts and various other features. I used to use it to supplement controls for Elite: Dangerous and it worked pretty well. I imagine it'd get tiresome for complex games but could be good for simpler games, and for other computer tasks. https://voiceattack.com/Default.aspx
There are tons of potential accessibility devices like specialized buttons and breath control etc, but they're usually expensive medical devices or custom builds. The other commenters have already mentioned the consumer products I'm aware of.
Star Trek still has traditionalists and hobbyists that prepare food without replicators. Sisko's father famously ran a Cajun restaurant in New Orleans. I wouldn't be surprised if someone ran a fast food burger shop because "the fries just don't crunch the same from a replicator" or something.
It also would be possible to have something like a replicator kiosk shop, which would be like fast food.
There are a few restaurants mentioned on the wiki, but they don't distinguish between traditional preparation and replicator food (it includes Quark's on the list). None of the space ones look like fast food though. https://memory-alpha.fandom.com/wiki/Restaurant
