The official credit list at the end of Hogwarts Legacy shows all the voice actors for the game but doesn't specifically reveal who performed which roles. Because of that, it's not entirely clear who is Sirona Ryan's voice actor.

The Hogwarts Legacy page on IMDB gives a clearer picture of who voiced what characters, such as Jason Anthony as the Sorting Hat and Lesley Nicol as Professor Matilda Weasley, but the majority of actors are still missing their contributions.

Despite the lack of confirmation, Twitter users believe Rebecca Root, a trans woman and actor credited for voice acting on the game, likely voiced Sirona. "Rebecca Root, a trans woman, is in the credits. If you listen to clips of her acting, it's pretty clear it's her playing the specific character," said one Twitter user.

The actor has not confirmed publicly if that's true, but those familiar with Rebecca's work are certain it's her voicing Sirona.
