It annoys me most when it's something that doesn't need a voice in the first place.

A few beeps would have done the job perfectly, but no, my bluetooth headphones insist on using the most awful sounding loud, nasally whingeing American harpy voice to say:
"Heeadphoenes conneecteed"
"Heeadphoenes disconeeected"
"powerrrrrrrrrrr ahfff"

Interesting, because as an American, I always switch my voice assistant to a British English opinion when possible because I find a lot of the American one to often have a Southern US dialect to them which I despise the sound of.

Guess American voice as a service deals seem to be cheaper for those companies

Most of the stuff i interact with lets you choose between both.
Supply and demand i guess.

One of the reasons I like my Sennheiser bluetooth headphones is the power on/off/recharge headset is a chirpy hampshire/oxofrdshire accent.

And the Sonys even more, as they just go "budoom" when you power them up.
