Animation/Machine Learning Mobile App

Hello, I want to animate the face of a 3D modeled character using machine learning. Specifically, using the data/images of babies and young teenagers facing expressions and body gesturing while singing. I know various places where to get such data in large amounts according to the required formats. The idea is to have our custom character sing to various songs played in the background. I am still familiarizing myself with the machine learning services released by AWS and Google Cloud. Please tell me briefly about your specific approach, experience with machine learning frameworks and what would you need me to provide (ex: 3d model of character), being as specific as possible, Thanks
