Calla Voice
Calla Voice is hands-free voice control for Windows — dictation, clicking, and commands in one program, built for people who can't use a mouse or keyboard. Everything runs on your own machine. Nothing you say leaves it.
Ask to join the beta 30-day free trial · no card, no account · Windows 10/11No mode switching. Say "scroll down" or "press control p" in the middle of a sentence and it just happens — while ordinary sentences still type normally.
Speech recognition runs locally on your own computer. No cloud, no accounts, no analytics, no subscription servers listening in.
Built and used daily by an active day trader. Instant commands fire in a fraction of a second; dictation keeps up with natural speech.
With the Chrome extension, say "click" plus whatever a button says. When several match, they're numbered — say the number.
Calla Voice was built by a quadriplegic who ran his computer — and his trading desk — by voice for 27 years. When the software he depended on stopped keeping up, he built his own.
The first thing he told his wife when it ran: "It worked beautifully." Calla comes from the Greek kallos — beauty — and the calla lily, shaped like a horn. That's the standard the software is held to every day.
Calla Voice is in limited beta. Every install comes with a 30-day free trial — just your name, no card and no account. It runs best on a PC with an NVIDIA graphics card, and adapts itself to smaller machines automatically.
