Yes, before they went "machine learning" all these assistants were much closer to command lines you spoke to - you had to learn the phrases, but they'd work reliably once you did.
I'd love something like this to run at home. Like an open weight model with a configurable command grammar that returns the most likely thing I said that matches the grammar. I've found things that are close but they have bits missing (like support for English) or aren't really open.
