What they did
He wanted to start Grok Bot voice chat hands-free. Using a USB mic (a small Bluetooth speaker with a mic works too) and the free, open-source openWakeWord, he first tested the built-in "Hey Jarvis" model. Then Grok Bot trained a custom "Hey Grok" model on his Mac, so saying it from anywhere in the house opens voice chat. It cost nothing.
How it went
Saying "Hey Grok" anywhere in the house opens Grok Bot voice chat on his computer, with no clicks and no extra cost.
Worth knowing
- X post by @Texas_Twins_Dad (Oct 25, 2026 Denver time): he used openWakeWord, tested "Hey Jarvis" first, then had Grok Bot train a custom "Hey Grok" model on his Mac; saying it opens voice chat.
- An always-listening mic should run locally only; check that nothing records or uploads audio until after the wake word fires.
Prompt

Help me set up a hands-free wake word on my [Mac/PC] that opens [Grok Bot voice chat / app] when I say "[Hey Grok]". Use the free, open-source openWakeWord. First get a built-in wake word working with my [USB mic / Bluetooth speaker mic], then train a custom model for my phrase on this machine and wire it to open the app. Show me each command before running it and tell me how to turn it off.
