Other comments say that these recordings are unlinked from your account after some time (6 months for apple) or you turn this feature off.

What just jumped to my mind is that, leaving aside how unique your voice can be, or how identifiable your behaviour and patterns are (hint: a lot), there are a lot of searches that reveal unmistakable and straight personal info. What about:
"Hey phone, text [name of my special other] [naughty and quirky stuff]"
I wouldn't care too much if someone listened to me ask for a Starbucks, but I certainly don't want anyone to listen to that.
