But it doesn't need to be my voice. It in fact should be illegal for Microsoft to use my voice for training without my express consent, and even then they must delete all models and data about it when requested. And it should be illegal for an employer to request or expect it.
One example mitigation I implemented at a local bank is to have them disable most aspects of internet access to my accounts. They are read-only from the internet and outbound wire transfers are blocked. They now require my physical presence and I make sure all the employees know me personally. I test them from time to time on the phone. My goal is to terminate business relationships with anyone I can not do this with. This will be too much for some people at first, having to treat every business relationship as hostile and I am not even sure I can get 100% completion of my goal
I do not know how to solve this on a global scale. I think the only way things start changing around this vulnerability is when powerful people experience shared pain. Lawmakers, executives, investors, etc... Such as businesses losing billions because some department thought they were talking to a real person and governments losing large amounts of tax revenue when more companies have this capability and it gets abused by deviants. Curious what happens when the fake POTUS calls the real Vladimir and Xi.
Any control over that is going to be through social and legal mechanisms, it isn't going to work to try to prevent access to the needed data.
I bet you haven't read their privacy policy. It starts with: "Your privacy is very important for us." /s
