// 仕組み
仕組み
- Run one Docker command
Pull a prebuilt image with the model baked in — CPU, NVIDIA GPU, ARM, and AMD variants exist. The server starts on port 8880.
- Point your client at it
Anything written for OpenAI's /v1/audio/speech endpoint works unchanged — just change the base URL to localhost:8880.
- Pick voices and languages
Choose from built-in voices, blend several into a mix, or generate a custom voicepack with the clone tuner.
- Generate with extras
Request SSML for fine control, or ask for per-word timestamps to build read-along experiences and captions.
// 機能
選ばれる理由
OpenAI-compatible API
A drop-in /v1/audio/speech endpoint — swap the URL in existing apps and keep your code.
Eight languages
English (US/GB), Spanish, French, Hindi, Italian, Japanese, Brazilian Portuguese, and Mandarin Chinese.
Voice mixing & cloning
Blend voices with weighted combinations or tune custom voicepacks from samples.
SSML + phonemes
Fine-grained pronunciation control, plus endpoints to generate phonemes from text and back.
Timestamped captions
Per-word or per-chunk captions for read-along UIs, subtitles, and karaoke-style apps.
Runs anywhere
Prebuilt images for CPU, NVIDIA, ARM, and AMD GPUs — plus Apple Silicon support when run directly.

// 自分で実行
自分で実行してみる
- Step 1 — CPU (laptops, servers)
Start the CPU image; the model is baked in, so there is nothing else to download.
docker run -p 8880:8880 ghcr.io/remsky/kokoro-fastapi-cpu:latest - Step 2 — NVIDIA GPU
Use the GPU image instead for much faster synthesis.
docker run --gpus all -p 8880:8880 ghcr.io/remsky/kokoro-fastapi-gpu:latest - Step 3 — Speak
POST to the OpenAI-style endpoint, e.g. http://localhost:8880/v1/audio/speech, with your text and voice choice.
// 活用例

// よくある質問
よくある質問
Is it free?
Yes — Apache-2.0 licensed and self-hosted. You pay nothing per character, unlike cloud TTS APIs.
How good is the quality?
Kokoro-82M is famous for punching far above its 82-million-parameter weight, with remarkably natural prosody for its size.
Which languages are supported?
Eight: English (US and GB), Spanish, French, Hindi, Italian, Japanese, Brazilian Portuguese, and Mandarin Chinese.
Kokoro-FastAPI or Qwen3-TTS?
Kokoro-FastAPI is lighter, faster, and dead simple via Docker. Qwen3-TTS offers larger, more expressive Alibaba models with streaming — pick by your quality-vs-speed tradeoff.
Can I use it commercially?
Yes — the Apache-2.0 license permits commercial use.
