Emma Watson speaks in a fairly 'neutral' RP, or Received Pronunciation. This is a fairly upper-middle class accent - but not the Queen's English as most people think. The accent you hear her speak in the video above is probably quite unvarnished. It is likely the accent Emma grew up speaking at home with her parents.
From what I've read, Harry Potter have 'London' accent. Not only Harry Potter, most of the characters in the movie (including Ron and Hermione) have SouthEastern British accent. One reason for that is, South East English accents are the most familiar British accents to Americans.
Hermione Jean Granger is a Muggle-born Gryffindor, who becomes best friends with Harry Potter and Ron Weasley. Rowling confirmed in a 2004 interview that Hermione is an only child. Rowling has described the character of Luna Lovegood as the "anti-Hermione" as they are so very different.
Firenze. The precise pronunciation of Firenze's name proved to be as mysterious to some of us as the vague premonitions he and his fellow centaurs made to Harry, Ron, Hermione and pretty much everyone else at Hogwarts. But we're disinclined to agree with Professor Trelawney that Firenze is a 'nag'.
Was Hermione a real name before Harry Potter? Aside from the character in The Winter's Tale, another famous 'Hermione' is King Menelaus of Sparta's daughter with Helen of Troy. In fact, it was from her that the name came from. After the Trojan War ended, Hermione was married to Neoptolemus, son of Achilles.

His Patronus is a dragon, since his name means dragon in Latin and he shows no particular fondness for any other creature. He could also have a white peacock Patronus, since Malfoy Manor has white peacocks at the entrance.
There are no swear words in the books. Rowling's editor wouldn't allow it, although she has said Ron would have swore a lot. Instead, he often says "bloody hell". Not true, Molly Weasley calls Bellatrix Lestrange a bitch in DH.
So from that, I would suggest this pronunciation: 'Ah-Gryd'. 'Ah', is an archaic phonetic form of producing a 'H' sound, hence why his named his 'Hagrid'.
The name Hermione is a Greek Baby Names baby name. In Greek Baby Names the meaning of the name Hermione is: Well born. Stone. Feminine name derived from Hermes. In Greek mythology, Hermione was the daughter of King Menelaus of Sparta and Helen of Troy.
In case you've forgotten that passage from Goblet of Fire, Hermione slowly sounds out her name in four syllables for Krum: “Hermione was now teaching Krum to say her name properly; he kept calling her 'Hermy-own. ' 'Her – my – oh – nee,' she said, slowly and clearly.”
"'Her – my – oh – nee,' she said, slowly and clearly," wrote Rowling about Hermione. Hermione's name isn't the only one commonly mispronounced.
In Harry Potter and the Goblet of Fire, Hermione dates Viktor Krum, a visiting student from the Eastern European magic school of Durmstrang. 'Hermione was now teaching Krum to say her name properly; he kept calling her "Hermy-own,"' the passage reads. '"Her – my – oh – nee," she said, slowly and clearly.
Harry used his signature dueling spell: Expelliarmus. Due to a combination of the Elder Wand's true owner being Harry, not Voldemort, and the spells colliding, Voldemort's Avada Kedavra rebounded upon him (again). Since at that point all of his horcruxes had been destroyed there was nothing to keep him alive.
Wingardium Leviosa. This is the spell that nearly ended Hermione and Ron's relationship way before it began, when Hermione went full know-it-all: 'It's Wing-gar-dium Levi-o-sa, make the “gar” nice and long.
