Local and self-hosted text-to-speech with Kokoro, the ~82M-parameter open-weight (Apache 2.0) model by hexgrad. Use when synthesizing speech offline, on-device, in the browser, or on your own server without per-character API cost — for high-volume narration, audiobooks, privacy-constrained pipelines, and prototyping. Covers running Kokoro via the Python `kokoro` package, ONNX / kokoro-js in the browser, and the OpenAI-compatible Kokoro-FastAPI wrapper; picking voices and language codes; blending voices; chunking long text; controlling pronunciation via misaki/espeak-ng; and judging when Kokoro is the right tool versus when its lack of voice cloning, narrow emotional range, and weaker non-English quality mean you should reach for a hosted or larger model instead. Not for voice cloning, expressive/emotional character performance, or high-fidelity multilingual work — say so and route elsewhere.

# Kokoro TTS (open-weight, self-hosted)
Kokoro is a small, fast, permissively licensed text-to-speech model. Its entire
value proposition is that you run it yourself: no API key, no per-character billing,
no audio leaving your machine. This skill helps an agent decide whether Kokoro fits a
job, run it through the right runtime, and get acceptable output — and, just as
importantly, recognize the jobs where Kokoro will disappoint the user and something
else is the correct answer.
