The sounds come from Jurassic World (2015), during Owen Grady's raptor training scenes with the pack including Blue, Charlie, Delta and Echo. In the film the Velociraptors communicate with clicks, barks and responsive calls that Owen uses with a clicker and hand signals. Clips of those training moments circulated widely on YouTube and soundboards as isolated dinosaur audio. Because the calls are distinct from a generic roar, editors keep reusing them for dinosaur memes, park scenes and suspense builds where a clever predator needs to be heard before it is seen.
