Although not all parrots can speak, those that do actually mimic the words they are hearing from humans.
parrots can squwark and can be trained to talk. If you want to do this you must say the word you want it to say and no other to it until it can say it. be prepared for this to take a long time.
they don't. they are extinct
yes, because they can speak,speak the same word for 1 week and they will repeat anything you say
"He does not", or, "he doesn't speak English" would be correct. It would never be 'he do not speak English,' as that is incorrect grammar.
Parrots ... and certain other birds ... are excellent mimics. They don't really "speak", they just repeat sounds they've heard... they can be trained in some cases to respond to specific stimuli in a particular way, though, which can give the illusion of them carrying out a (pre-scripted) short conversation. As to HOW they do it.... how do YOU do it? You have a tongue and a voice box. So do parrots.
To attract mates and show off. Quite simply, parrots are social creatures, and imitating sounds, including spoken words, is their way of communicating. Parrots are more likely to imitate speech if they have no other birds of their own type around.

"I can't speak English!" in English is Non parlo l'inglese! ("I don't speak English!") in Italian.
All parrots can talk, some better than others and it will vary bird to bird in a species. Some are smarter than others.
