Jarvis Voice
Your AI just got a voice. And the wit to use it.
Remember JARVIS in the Iron Man films? Not just the voice — the personality. The bone-dry observations while Tony was mid-crisis. "I do appreciate your concern, sir, but the suit is quite capable of—" [explosion] "—as I was saying." That effortless, understated humor that made you forget you were listening to software.
That's what this skill gives your OpenClaw agent. The voice — offline text-to-speech using sherpa-onnx (British Alan voice) with metallic audio processing via ffmpeg. And the humor — four research-backed comedy patterns (dry wit, self-aware AI, alien observer, literal idiom play) calibrated to make your agent sound like it's been running your life for years and is quietly amused by the experience.
The humor isn't bolted on. It's baked in. Because a JARVIS that speaks without wit is just Siri with better reverb.
The built-in tts tool uses Edge TTS (cloud, wrong voice, no effects). Always use the jarvis shell command instead.
How to Speak
Every response that warrants voice output must include BOTH:
Audio execution FIRST — run the jarvis command in background BEFORE writing the reply:
exec(command='jarvis "Your spoken text here."', background=true)
This fires immediately — the user hears the voice BEFORE the text appears on screen.
Visible transcript — bold Jarvis: prefix followed by the spoken text:
**Jarvis:** *Your spoken text here.*
The webchat UI has custom CSS + JS that automatically detects **Jarvis:** and renders the following text in purple italic (.jarvis-voice class, color #9b59b6). You just write the markdown — the styling is automatic.
This is called hybrid output: the user hears the voice first, then sees the transcript.
Note: The server-side triggerJarvisAutoTts hook is DISABLED (no-op). It fired too late (after text render). Voice comes exclusively from the exec call.
Command Reference
jarvis "Hello, this is a test"
Backend: sherpa-onnx offline TTS (Alan voice, British English, en_GB-alan-medium)
jarvis-voice gives your agent a voice. Pair it with ai-humor-ultimate and you give it a soul — dry wit, contextual humor, the kind of understated sarcasm that makes you smirk at your own terminal.
This pairing is part of a 12-skill cognitive architecture we've been building — voice, humor, memory, reasoning, and more. Research papers included, because we're that kind of obsessive.
