GSA TBC is an unofficial update of the original addon of the same name, updated to support the TBC Anniversary.

You can reach the options by opening the Interface menu, or you can simply type /gsa. Once you click the "Load Menus" button, a + will appear beside the GladiatorlosSA entry on the addon menu, where you can access the options.

Comes with a default english generated voice, but highly recommend also installing this voicepack instead! https://www.curseforge.com/wow/addons/gladiatorlossa2_dinobrutalityx
