This is an Anki extension that integrates Kokoro-FastAPI to generate TTS (text-to-speech) audio from selected text in the card editor. KokoroTTS is an LLM that runs on your local hardware, meaning it's free and you don't depend on external APIs.
- Adds a TTS button to the Anki card editor.
- Generates audio using Kokoro-FastAPI and inserts it as a
[sound:...]tag in the current field. - Supports automatic Kokoro-FastAPI server startup and shutdown (UNIX only, optional).
- Configurable voice, API endpoint, audio format, and more.
- Anki (recent versions)
- UNIX-based OS (for autostart/shutdown features)
- Kokoro-FastAPI running locally or remotely
- Install Kokoro-FastAPI
- Download or clone this repository.
- Move, copy, or symlink the entire folder to your Anki add-ons directory.
- To find your add-ons directory, in Anki go to:
Tools→Add-ons→Open Add-ons Folder.
- To find your add-ons directory, in Anki go to:
- Restart Anki.
- Configure extension
Tools→Add-ons→config."path_to_kokoro_executable"is required to configure.
voice: TTS voice name from KokoroTTS.api_url: URL of the KokoroTTS API server.autostart:"true"to auto-start KokoroTTS server if not running.path_to_kokoro_executable: Absolute path to the KokoroTTS startup script (e.g.~/kokoro/start-gpu.sh).audio_format: Output audio file format (e.g.,"mp3").shutdown_by_timer:"true"to auto-shutdown KokoroTTS server after inactivity.idle_timeout_in_seconds: Seconds before Kokoro shuts down.
- Open the Anki card editor.
- Select text in a field and click the TTS button.
- Audio will be generated and inserted as a
[sound:...]tag.
- Because the TTS button essentially launches another, "heavy" project, the first press may take some time—for me, it's around 7 seconds. However, since everything runs in parallel, you can continue filling out the card while Kokoro is loading.
- Autostart and shutdown features require UNIX OS.
- KokoroTTS server must be accessible at the configured
api_url. - The extension will attempt to start the server if
autostartis enabled.
