Please Help! My father is being scammed!

The woman in the video is Larissa Liveir, a Brazilian Guitarist. She's sponsored by Gibson. I'm not sure if the video was created with ai or not. The video was sent to my 70 year old father from a scammer pretending to be her. I know the voice is not hers. First she's Brazilian and her native language is Portuguese. The real Larissa Liveir does speak English but I assume with a heavy accent. There's no accent in this. Can someone please tell me if the video is AI?
