How about medical equipment? Like one of those in ear themometers maybe, the ones for the mouth exist but per my experience they’re pretty delicate. I also think things such as heart monitors exist but is far too expensive or too inaccessible. Suff like blood pressure machines are usually inaccessible.

I think exercise equipment can be more accessible, such as a talking treadmill or an exercise bike, etc.... Yes, I think you can get simple ones and work without speech but not every feature on those are accessible.

A talking treadmill or exersize equipment would be awesome. Or an app that connects via bluetooth to the treadmill and is fully accessible would be great.
