This old post of mine may be of interest, where I point out: "After a bit of threat modeling, it becomes apparent that future spearphishing robocalls may not directly con you, but rather “farm” your voice data by asking you benign questions, and use that to train a voice model to penetrate more deeply into your network." A lot of this writing has been on the wall forever and many (I'm sure otherwise smart people in) mission critical industries like banking, ISPs, and more refused to even acknowledge the risks.

2021 - "Despite the prevalence of deepfake audio tech, banks and ISPs rush ahead with “voice print” authentication" https://keydiscussions.com/2021/12/07/despite-the-prevalence... ends with a section called "The next crisis: robocalls that spoof the voices of victims at scale"
