Google Meet Auto Unmute

Ever started talking in a Google Meet call and realised — too late — that you were muted the whole time?

Auto Unmute fixes that. It watches for mouth movement (using your camera) and recognised speech (using Chrome's built-in Web Speech API) and, the moment it detects you actually trying to talk while muted, it sends the same Ctrl+D / Cmd+D shortcut you would have pressed yourself, and unmutes you within roughly 400 ms.

It is the inverse of the popular open-source extension "Google Meet Auto Mute" by Morpho, Inc. Where that extension mutes you when you go quiet, this one unmutes you when you start talking — and only in that direction. It will never mute you on its own.

KEY FEATURES

• Auto-unmute on speech: dispatches the standard Meet mic-toggle hotkey when sustained speech is detected.
• Two complementary detection engines, selectable in the popup:
– Image: local mouth-movement detection via the open-source face-api.js library.
– Speech: Chrome's built-in Web Speech API.
– Both (default) for maximum reliability.
• Tunable sensitivity: pick how many consecutive 200 ms frames of speech must occur before unmuting (1 to 10, default 2 ≈ 400 ms) and how open your mouth must be to count as "speaking".
• Camera selector and speech language selector.
• Optional live activity panels in the popup so you can see exactly what the extension is detecting.
• Never re-mutes you on its own — only you decide when to mute again.

PRIVACY

100% local. The extension does not collect, transmit, store, or share any user data. No analytics, no telemetry, no remote servers, no third parties. Your camera and microphone streams are read frame-by-frame in your browser and immediately discarded. Only your settings are saved (via Chrome's standard sync storage).
