building a netflix like movie library with speech recognition

This is a UI related question any pointers, examples or links would be greatly appreciated.
Can I use Unity/Unreal to build a UI ( mobile app i.e gearVR) for a custom movie library with search and speech recognition features , if not how can I go about doing something like that. Thanks.

 

Yes. After all, it's just software...

 

Thanks, since I'm not super familiar with game engines and their capabilities or limitations with UI building and server side mapping of the content I wanted to see if someone else has done something along those lines and had any feedback or recomendations.
