Vocal mimicry is a feature of many Bio-Masks and is used as a lure by many Yautja to attract humans. Often containing distress calls (Help me, help me!), beckons (over here!) or insults (Come get some, freak). The Predators can produce these mimicries anywhere, attracting the attention of a Marine. Predators have been seen to copy the phrases used by soldiers and when it is played, it seems disturbingly warped, as seen In Predator, when Dillon is thanking Mac for stabing a scorpion that was on his shoulder, the Predator is heard playing their voices back.
