how to run text-to-speech AI locally — free voices, and voice cloning, on your own machine

Best lightweight narration: Kokoro-82M — ~2-3GB VRAM, runs on CPU, 54 voices, Apache 2.0 (commercial-OK). Can't clone.

Best open voice cloning: XTTS v2 — clones from a 6-second clip, 17 languages (non-commercial license).
