UX rol question (Specific for my project) [on hold]

I am studying Communication and multimeda design and it's time to graduate. I have a free project ahead of me, where i want to learn more about UX. So i chose the UX designer rol.

I am thinking of a project to make an audio experience for blind children. My teacher said that i made the focus too much on the "audio" and that i need to focus on a UX task.

Can you help me with a direction so i can do this project but the focus is more on a specific UX task?
