How to make a live voice sound like man and woman.

Hi. We are currently working on a project where we are using pitch shifting to try to change male or female voices to sound sexy.

Right now, pitch shifting sounds very robotic and non human, our desired affect is to create a patch where when someone talks we can make them sound similar to perhaps for example Barry white or Jane Birkin.The main goal is to make people sound sexy.

We have attached the patch we have began working with right now. Does anyone have any advice, patches or suggestions on what we can perhaps do to get a cleaner more human sexy sounding voice.

Thankyou
Miyashi
