While Araki clarified that "Wryyy" is the sound he believes vampires make, you cannot make the argument that it is a result of DIO's vampirism and not just DIO's genes in general; after all, Jolyne inherited "Ora" from Jotaro, although she could have just picked up the mannerism from his behaviour if he was even around her enough for it to pass on, and Giorno inherited "Muda" from DIO as well. I believe that the effects of the Stone Mask are not hereditary, plus since vampires are shown to otherwise act and function as undead, it is likely that, other than DIO who had access to Jonathan's body, they are unlikely to be able to breed either.
