Like chickens.

I'm not even joking. The sounds ours make would be terrifying if they were the size of an ostrich, much less a trex

Have you ever heard big cats? They sound like little cats but... deeper. I feel like dinosaurs would sound like birds with similar deepening, depending on the size of the dino.

Did you know that turtles scream when they, uh, copulate? Imagine how loud a dinosaur would have been.

Probably something like this

I'm not sure, but considering most animals make at least some sounds none of us would guess came from them, I wouldn't be surprised if the topic of their vocals was just abandoned by science and left up for interpretation.

Jacha-chacha-chacha-chow!

Kinda like birds, but much deeper/lower & also slower. Instead of making 12 sounds in 1.5 seconds, they would maybe take like 6 seconds to make the same 12 sounds.

You ever hear lyrebirds? Usually they'll mimic the environment but sometimes they'll sing in a way you swear was right from the Jurassic. They definitely don't roar, that came from the junk era of paleontology when people were just hip-firing and assumed they were giant lizards.

What do you mean? Didn't you see the historical documentary "Jurassic Park"?

Never give up, never surrender!

I'll be very disappointed when they finally clone a real life T-Rex from DNA preserved in amber, and it won't sound like it's supposed to, meaning like Gary Rydstrom decided how they should sound.

I like to imagine they all sounded like pigeons.
