Narration and text-to-speech on the user's machine through Guaardvark's Audio Foundry (Chatterbox, Kokoro, Piper) and consent-gated voice cloning from a reference clip. Use when the user wants a voiceover, narration of a script, a spoken line, or "make it sound like this voice".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Voice with Guaardvark
Read `setup` first. Expressive voices need the `audio_foundry` plugin running;
Piper works without it. `B=${GUAARDVARK_URL:-http://localhost:5000}`.
## Which engine
| engine | route | when |
|---|---|---|
| Chatterbox | Audio Foundry `backend: "chatterbox"` | expressive, emotion presets, **cloning** |
| Kokoro | Audio Foundry `backend: "kokoro"` | fast, clean, 10+ built-in voices (`af_heart` default) |
| Piper | `/api/voice/text-to-speech` | offline fallback, no GPU |
`GET $B/api/audio-foundry/voices` lists what is installed. `GET $B/api/voice/voices` lists Piper voices.
## Speak a line or a script
Over MCP, call `generate_speech` (`text` up to 3000 characters, optional `voice` such as
`af_heart`, `engine` auto | kokoro | chatterbox); it waits and returns the file with a download
link. Cloning is not offered over MCP. Without MCP, or for the Chatterbox knobs, use REST:
```bash
curl -s -X POST $B/api/audio-foundry/generate/voice -H 'Content-Type: application/json' -d '{
"text": "The line to speak.",
"backend": "auto", # auto | chatterbox | kokoro
"voice_id": "af_heart", # Kokoro voice, or omit

How to install
mdr add guaardvark/guaardvark/voice@sha256:1e3c0a4f720d23acThe line at the top of this page pins the label git:20261006.ce3280e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
