Your privacy
"This call may be recorded" is old news. What happens to the recording now is the new part.
Companies have recorded calls for decades. That part isn't new, and in most places it's legal as long as they tell you. What's new is what the recording becomes after you hang up.
It used to sit on a server and get ignored. Now it can be turned into text, searched, and in some cases used to train AI. Your voice, and what you said, can become data that sticks around.
What companies are allowed to do with your voice keeps shifting. I send the changes that actually matter to you and skip the ones that don't.
What to do
If your bank offers voice ID as the only way in, ask for a second step too, like a code or a password. Your voice is easier to copy than it used to be, so don't let it be the only key to your money.
Ask the questions above and you're ahead of most people. When something changes about how your voice gets used, I'll let you know.
