I cant edit the sound bank! Well, i CAN but only the default speech and have no idea of where are the files of the others (like thespian, my favourite)

Anyone knows where are the others WAVs?

On your CD, in Data\User\Speech.

Thank you very much!

As a side question...I have my own custom soundbank. Can other players hear it or does it revert to some default?

it reverts to the Default one if the others dont have it with the same name and file names.

it reverts to the Default one if the others dont have it with the same name and file names.
You wanted to say "with the exact same folder name".
(The file names are are the same for all speechbanks anyway.)

That means, one should always use the folder name or the name of the zip file that you downloaded the speechbank in.
