Text to speech Engine subsystem ¿change voice?

Hello! I have the “Text to Speech” plugin installed and working correctly, but I would like to have an in-game menu to be able to choose the voice from the ones installed in windows.
If something like that is impossible, at least I would like to change it while working on the game because it is really unpleasant to hear when it reads texts in Spanish instead of English. I have installed a Spanish voice that is chosen as default, but unreal doesn’t seem to care about that.

Greetings and thanks in advance.
