What makes you sound like a robot when a phone or video call is lagging?

I get that it’s connection issues, but why the “robot voice” and not static or something?

Lossy compression. In order to save bandwidth, the transmitting computer converts the speech into a bunch of tones, cuts out those which matter the least, and sends the instructions for how to play the remaining ones to the receiving computer. This normally works amazingly well, and your voice can be transmitted using little data. But if the connection is slow, the compression is increased by cutting out more and more significant tones, making the voice sound more and more robotic. And if the connection drops completely for a moment, the computer may mask this by continuing to play the last tones it received until new ones are available, making for a droning buzz of the last syllable received. It’s often a better alternative than silence for short stutters.
