@ Warrof, the new technologies used in the Memorial Edition are incompatible with the translation tools available, unfortunately. I'm looking at getting it to work, but it's unlikely to happen within the next year.
I think it's ok to use the Full Voice version after buying the Memorial Edition, but that's just my personal stance.
