This isn't about pausing anyone; it's about doing faster-than-realtime processing after a delay event. Humans can do that to some extent, and this is in fact done with some voice applications like Microsoft Teams, where after a network interruption the audio is sometimes played back really fast until the point that it becomes real-time again.

I hope it's an intentional design decision, because it works really well (for me). I can often perfectly keep track of a conversation in spite of the network delay. As much as I hate Teams, its meetings and voice implementation (also noise cancellation) works quite well, especially compared to current open source solutions like Jitsi or BigBlueButton.
