It wouldn't be a League of Legends rework if there weren't a lot of aesthetic changes for the champion, and Irelia's rework is no exception. Along with her extensive ability changes and visual update, she's got a whole kit of new voice lines by a new actor.
This update, as well as the details of her rework can be found in the Public Beta Environment patch notes. Considering that she has over seventeen minutes of voice footage, it's likely that she's getting different lines for her various skins.
Irelia has been long overdue for an overhaul after multiple nerfs. Riot Games finally giving her a shiny new makeover, is a much appreciated gesture for old League fans.
