looking for specialist for tv-series dialect/accent

[elooije]

dear community,
not sure if this the right place, if so please point me in the right direction.
for an international tv-series I would like to polish the actors performance to make them sound the same.
the cast, from all over the country, need to sound like they are from the same family talking with the same accent/dialect. they will learn their lines using pre-recorded samples and there is a dialect coach on set, but it will never sound coherent.
I'm looking for someone who can develop a language model with the applicable accent, to make sure the actors performance will be polished by this new AI language model of the dialect-language.

Respeecher and Elevenlabs can lead to the same endresult, but they throw away the actors performance, and make the voice-actor (with the right dialect) sound like the on-screen actor. that's a nuance difference that is sensitive in the actors community.

Thanks!

एक घर है जिसमें कोई दरवाज़ा नहीं,
न खिड़की, न छत, न दीवार।
फिर भी उसमें कुछ छुपा है ऐसा,
जो सुबह उगता है और रात में मर जाता है।
न इंसान इसे बना सकता है,
न तोड़ सकता है, फिर भी हर कोई इसे देखता है।
बताओ क्या?
