Kokoro TTS
Kokoro is a lightweight open-source voice generator with over 50 voices that runs smooth even on weak hardware. Great for audiobooks or streaming.
Overview
Kokoro TTS is a voice tool that sounds way better than you'd expect from something this tiny. It's free to use thanks to its Apache 2.0 license and weighs in at just 82M parameters. That means it can run smooth on laptops or small devices.
It’s got over 50 voices covering US and UK English French Japanese Mandarin Korean and more. You want fast? It runs in real time even on CPU. You want to tweak it? You can self-host it change voices or plug it into your app with OpenAI-like APIs.
Built with power tech but easy to run
Kokoro uses StyleTTS2 mixed with ISTFTNet which helps it sound more natural without needing huge compute. You don’t need a beefy setup either. It supports ONNX and PyTorch and you can even throw it in Docker.
It’s small but it beats bigger systems like XTTS and MetaVoice. You can use it for audiobooks, podcasts, games, embedded devices, accessibility or anything you want sound in.
Community tools make it even easier
There’s tons of wrappers and demos already. Like:
- kokoro-tts. CLI tool that reads EPUBs and PDFs
- Kokoro-FastAPI. Add GPU or ONNX backend with OpenAI-style endpoints
- StreamingKokoroJS. Lets you stream voice straight in browser
- Kokoro-Web. Desktop and web demo that just works

Most people think Kokoro TTS sounds amazing for its size. They credit it to high-quality synthetic training data and tight voice targeting. But they also point out it lacks open voice cloning and struggles with unseen voices.
Kokoro is basically a trimmed and modified StyleTTS 2. But instead of trying to cover every voice in the universe it sticks to a few very clean ones. The training data seems to be mostly ElevenLabs and OpenAI voices which are already top-notch. That alone gives it a huge edge.
