Ask HN: Voice Conversion Methods

Hi All, I've been doing research on voice-to-voice technologies and have made some attempts to train a model with Retrieval-Based Voice Conversion but I struggled to complete the process due to software bugs/dependencies I didn't have time to resolve. I plan to make another attempt at training a model soon and would like to ask if anyone can recommend me any practical advice or resources for achieving this? My personal use case is to replace the narrator of a purchased audio book with it's author (if possible) instead of the voice artist. It is common to find high quality speech available from authors to train a model with. It can be very distracting and frustrating to listen to books with accents and pronunciations that are unsuited to the material. Thanks in advance
