Some intrepid data miners who have the beta version of Street Fighter V unearthed some in-game audio files of a female voice announcing character names. Each character revealed so far in the game is among the discovered audio samples, along with other interesting names: Guile, Juri, Urien, Alex, Ibuki, Bison (Balrog/boxer) and Fan.
You can hear the names here.
Also in the same set of leaks are audio files of the same female voice announcing names of Capcom Pro Tour events and their host countries. It's still a wonder what role these will play in the final build of the game, so let's just all wait for SFV to come to the PlayStation 4 and the PC on February 16, 2016.
