Using an existing voice line and modify it ?

[HakkamDaRed]

Hello there,

I'm quite new to this, I followed several tutorials and know how to use Alltalk to create basic voice lines.
It appears to me that the most difficult part is to have an accurate tone and behavior in the created voices.

Like, you have to have a model that is a "only whispering voice" model in order to have whispering voices coming out of the AI.

So I wondered if I could take an existing line (like "You shall not pass !" in LoTR ) and apply an RVC or else onto it, in order to change the voice, but not the intent in the voice.
Is that possible ?

How do you usually do to mix voices intentions with a particular voice (morgan freeman or else) ?

Thanks for your time, have a great day ;)
