Need help with Sella (Fate, Haruhi Nanao) RVC model on Russian
Hello, sensei! For a couple of months, I've been trying to create my first voice model for personal use (voice packs for home appliances like robot vacuum cleaners) on a loose schedule. I chose Sella (セラ) from Fate.
Due to her relatively rare appearance in anime, I only managed to collect 7 minutes and 30 seconds of clean recordings. I initially trained her from scratch, but since the dataset was Japanese, she handled Japanese lines well (like Leysritt's). However, when switching to my language, Russian, she lost the pronunciation of the Russian "R"s and began to sound unnatural.
My second attempt was to train a model based on RIN E3, but it didn't improve. I searched online for ready-made models (again), but due to restrictions in my country, I couldn't find anything.
Do any of you have any tips on how to get out of this situation, or is there a ready-made model with a voice that closely resembles the original Sella speaking Russian?
I think I've tried every possible output settings and every model checkpoint for 100-500 epochs.
I use Applio 3.3.0, UVR5, and Audacity, and I do everything on my PC. Gemini helped me understand the process.
