For anybody else who also hadn't come across the term RVC before:

"The RVC model is a Retrieval-based Voice Conversion system using AI for high-quality voice cloning. It utilizes artificial intelligence to modify or clone voices in real-time." Source: https://speechify.com/blog/rvc-vocal-models/

Wow. I'm going to give each family member a password and make them prove that they're real when they call me :)

or go pro and issue a One Time Pad to each of them.

Would make a nice vignette in a film about a dystopian future where video can be be generated cheaply and of sufficient quality.

Yeah but I tried Audimee too and they are working on giving best quality voices. It is not about u train or use RVC, it is about quality and save time.

Now if only the prices would drop and I could start making custom audiobooks for the price of regular audiobooks.

Great, so the competition is going to yield cheap services with a nice UX.
