I'm working on an app, and I would like users to be able to use it hands-free in certain views. Basically, press a specific button with a voice command.

The scenario is similar to tracking inventory, so you'd have the app in an item's view, and as you go you'd tell the app something like "Increase", and the count of items would increase.

I looked into the Speech framework, and I can see them pressing a button when the inventory starts and pressing it again when it ends, but I don't know if a lot of ambient noise, people talking normally, and being on for maybe hours at a time is a good idea.

I also looked into shortcuts, but they seem to work even when your app is not open, so I don't see how that would work, since you need to select an item to count first.

Is there a way to do it more like Siri, where you'd say "Siri, increase" or "App name, increase" while on specific views in the app and it doing it?
