This and other discussions on HN make me think on the fact that so much of your voice has been recorded by companies when you call their support lines. Are these troves of voice recordings stored safely with appropriate levels of access control?

I mean most people can usually pick up on the difference between a voice recording and a generated voice sample based on the recording. Have there been studies where generated voices are then subjected to telephone compression and layered with background noise to appear to be a phone call from a car?

If DeepFake voices only need 5 second clips to produce good enough versions of anyone's voice and any discrepancy in quality could be attributed as a bad telephone connection or masked with background noise, is anyone really safe?
