+
+- Vietnamese M.C. Nguyễn Ngọc Ngạn
+- data scraping code: https://github.com/phineas-pta/speech-synthesis-ngngngan
+- 6h30min audio at 48 kHz + RMVPE pitch extraction = 16.1 GiB disk space
+- batch size = 8 ⇒ 1 epoch = 1053 steps
+- train locally from scratch, ≈ 10’30” per epoch
+- train 300 epochs, save ckpt every 5 epoch, select ckpt at 160th epoch
+- i haven’t tested all the models 1 by 1
