Kokoro
A small, open-weight text-to-speech model that produces natural voices on modest hardware.
Kokoro is a compact open-weight text-to-speech model. Despite its small size it produces natural, pleasant speech, and it runs comfortably without a heavy GPU.
Its Apache licence and modest footprint make it the practical open choice when speech synthesis has to stay local.
Where it fits
A fit when you need good-quality, self-hosted text-to-speech on limited hardware, with a permissive licence.
Where it does not fit
Not the match for the most expressive, emotionally nuanced output: a hosted premium voice still leads there.
