I am fully in favor of team "I'm never sending my voice anywhere", but assuming a locally-hosted voice control I'll say: voice is a great interface around the house.
If I'm preparing to leave and wonder whether I should bring a jacket, yelling "what's the weather like?" is much more convenient than taking out my phone (or go pick it up from the other room), unlock it, go to the home screen, open the weather app, wait 2-3 seconds and then scroll to the full forecast.
I'm not saying that checking my phone is an annoyance - it's still much better than checking the newspaper. But being able to keep my uninterrupted focus in what I'm doing is the type of luxury one only notices once it's gone.
I've never liked any answer I've gotten to questions like "what's the weather like."
I look at the forecast in my weather app -- the whole fullscreen thing -- and follow some sort of mental algorithm that I can't fully specify to arrive at the conclusion about what to wear/bring. The spoken data feels like it's missing something, or maybe it's just transmitted in a sequence that my brain can't work with.
It's not that I don't trust it, exactly. It's that I can't use it for the task I'm trying to do. Never could. I have this problem with a lot of voice interfaces, and it suggests to me that either a) they're not very good, or b) my brain is not designed for that kind of UX.
It's certainly gives a very different kind of answer than my roommate would. Often times the most useful answer to receive can be "exactly like yesterday" or "slightly warmer/colder" - a voice assistant wouldn't do that.
