Noticed something strange...Normal?

Hey guys, new to me 2018 GLE 3550. Still tinkering to get used to all the bells and whistles. As per usual, Chicago has been experiencing some "go home, you're drunk" weather. One day it'll be 80F+, the next day 40's. On one of the hot days, I had the AC on full blast, loud fans. I hit the voice command button, and the fans automatically turned to low, quieting the fans, then back to high after the voice command was done. Is this normal and a convenience thing by MB, or is something wrong and my AC about to go?

normal, it is meant to do that so the system can hear you better, MB's attention to detail. Congrats on the purchase.

MB’s of all kinds.
Perfectly normal. I had this way back in 2011 on my first W212. I remember the first time I experienced that.
