Amazing vocal skills

The parrot is distinguished as the only animal capable of imitating the human voice, and repeating some of the words and sentences that it hears frequently from those around it, but how can this bird pronounce some human words clearly?
Acoustic memory: The brains of parrots differ in their structural structure from the brains of the rest of the birds. The strength of the parrot is in its vocal memory, which makes it able to store and imitate speech within a short time in a beeping manner, as the cortex surrounding the vocal centers in the parrot’s brain plays a role in helping it to learn easily and imitate subtly sounds.
