looking for an ai to replicate a persons voice from a video & say a new sentence

I’ve heard it can be done but can’t find how so im hoping someone can point me in the right direction.

my partner’s mum died unexpectedly recently and whilst there are some videos of her there aren’t any where she is talking to my partner, no voice messages saying i love you etc its been hard on my partner and i was hoping to use the 2 videos i have with her speaking in them to clone her voice and have it say something like love you son etc is this possible?

the videos i have of her speaking total 7ish minutes of footage but there is background noise.
