Read setup first. Expressive voices need the audio_foundry plugin running;
Piper works without it. B=${GUAARDVARK_URL:-http://localhost:5000}.
| 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.
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:
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

Build consistent characters, environments and props in Guaardvark's Cast Library and train LoRAs for them locally (reference photos → vision bible → sample plan → approved samples → training). Use when the user wants the same face or object across images, videos, a music video, or a Film Crew production, or asks to "train a LoRA".

Code intelligence over repositories Guaardvark has indexed: semantic code search, exact-text search, file listing, PageRank repository map, import dependency graph, reading one class or function, analysis and generated rewrites, plus the System Mapper and self-improvement status. Use when the user asks where something is implemented, how modules depend on each other, or wants an architecture map of an indexed repo.

Add any Hugging Face image or video model, checkpoint or LoRA to Guaardvark from a URL, list what is installed, and download registry models on request.
