It's probably stuck in legal limbo in the EU. The recently passed EU AI Act prohibits "AI systems aiming to identify or infer emotions", and Advanced Voice does definitely infer the user's emotions.

(There is an exemption for "AI systems placed on the market strictly for medical or safety reasons, such as systems intended for therapeutical use", but Advanced Voice probably doesn't benefit from that exemption.)

Yes, but it works with a vpn and the change in latency isn’t big enough to have a noticeable impact on usability.
