Alternative to Google Shopping List

I am looking for an alternative to Google shopping list, self hosted if possible.

KitchenOwl looks promising. Nextcloud and Homeassistant also offer something like this.

But: I would like to add items to the shopping list via voice control (smart speaker). Does anyone have experience with this or an idea how this could be implemented? I mean, I can already control devices in Homeassistant via Google Assistant, which works perfectly. But adding items to a list?
