Can you please tell me if there is any software to change my recorded voice to my friend's voice?
I suppose, there is no software to change the recorded voice to someone else's voice because it's difficult to program that voice and develop the plug-in to resemble the characteristics of that person.
Browse the database of Software Informer to look for applications that can change your voice to pre-defined ones.
