how to make custom announcers ?

[wsa30h]

how do i make an entire new clone wars or galactic civil war announcer sounds ? i only need to replace the default announcer for when the hero bonus is active. i know that i can just delete the lines in the lua but i would like this to be professional. i know giftheck has done it so if he cpu;d ;eave his cw or gcw vo folder along with the streams that would be great.
