When will you add custom voices for both text-to-speech and voice to voice calls?

because just like character.ai, I was hoping this site also has the similar voices,

I hope you guys add it later, because that would be really nice so we can have full control of what models we can use but also make character models we wanted,

or unless you can redirect me how to add custom voices, because some of them don't have the last time I experienced it
