I need an API build for my project

I spoke with someone who is tech-savvy and asked if they knew of an AI that could convert voice notes into videos. They mentioned that an API would need to be built for that, and I was wondering if anyone here could do such a thing and what the cost might be. You can comment here below or send me a DM. Here’s part of our conversation:

“I’m looking for an AI that works on both phone and laptop. It should allow importing a voice recording to create a digital avatar and generate a background based on the content of the voice recording.”

“You would need to build it into an API, I don’t know of any model that can do that by default.”
