Yes, I have a specific requirement for a mod I'm working on. I expected I would have to use a digitized voice which would be male, or at best non-gender.
I am working on a mod to replace the Great House vaults in Vivec. The Telvanni vault uses a creature named Nergel who is a demi-god, the mother of all scamps, who has been enslaved by the Telvanni to act as a gate keeper for their vault. To loot the vault the player must befriend Nergel, feed her to make her stronger, and then agree to a quest to retrieve her heart that has been stolen by the Telvanni. On completing the quest the door to the vault is opened, but Nergel betrays the player and trys to kill them.
Three voices are needed. A child-like idiot voice while Nergel decides if they will befriend or eat the player. An adult voice when Nergel is stronger and explains the quest to the player. Finally, a god-like voice once Nergel has it's heart, and then considers all mortals as irrelevant. For the god-like voice I will have to use a lot of digital enhancement. My idea is to use short introductory voice sequences accompanied by longer text dialogue. Voice examples are "Nergel hungry, hungry!", "Listen carefully hero", "Children, kill the mortal!".
I am glad to hear from your site that you have an English rather than American accent as the female voice is more resonant and easier to manipulate with filters. I will be using pitch change and distortion to get what I want. Sorry, but the final voice may not sound much like your real voice.
I have most of the elements of the Telvanni and Redoran mods completed but I cannot say when it will be released. If you are still interested let me know.
