Product Overview
Protecting Voice
Blocking Your
Smart Speaker
Using light to deafen a microphone might sound like magic;
it is anything but. Our core technology (the Light Induction
Microphone Barrier) creates a physical shield against unwanted eavesdropping — a barrier no malware or hacking can circumvent.
How It Works
Our first product, the Talklock is an internet-disconnected,
voice-operated device that gives consumers the freedom to use
Siri, Alexa and other virtual assistants and still only be heard
when they choose.
The Talklock for the Amazon Echo Dot incorporates four LIMB Lasers to jam the microphones of the Alexa device. When a locally processed wake word is spoken, the TalkLock turns off the lasers, allowing the user to interact with the Alexa device before returning to “privacy mode.” Our device, having no radio or memory, does not and cannot send any information over the internet nor can it record any data.
