Glow-TTS + fine-tuned HiFi-GAN (LJ Speech) is an open-weights text-to-speech model from VITS study (public implementations), released June 2021.

Catalogue identity notes

Exact ljspeech system in VITS Table 1; HiFi-GAN fine-tuning is a distinct vocoder configuration. Published implementation/checkpoint links in §3.4; no generic Tacotron or Glow-TTS score substitution.

Each result implies a score on its own, after adjusting for how hard its test is and who ran it. The score is their weighted average, with a small pull toward the middle for thinly tested models. Each test's weight is its counts column above; here it's added up by who ran the tests. How it works
