A distilled Kokoro-82M af_heart voice (7.6M params) went from 15x realtime to roughly 50x on one i7-14700K core, with the file shrinking from 8.46 MB to 3.56 MB. Training ran on a single 4070 Ti Super over about a day, with each weight change gated on 400 dev sentences x 3 seeds plus 1,600 held-out sentences.
