I was recently astonished when using speech recognition software on my computer finally made the computer silent. So when I use the speech recognition, my fan just stops. I investigated it and it does not stop, but the speech recognition software seems to slow down the fan to the minimal speed, even though the CPU cores are getting hotter and hotter. You never know these days what programs do.

Is it a Mac ? I think Macs always do that when they're actively listening with the internal microphone.
Yes, it's a Mac. An iMac, pretty old iMac. I did test it with Siri and that doesn't turn down the fan.
That is something that Macs do at the system level (if you were experiencing this on a Mac)
