Accessbility and Static Content (copyright)

Hi! I'm updating one of my sample modules to meet Accessibility standards.

I understand all the material I've read regarding functionality, focus, font, colors, images, etc.

I have audio in my module. How does this work with a learner who uses a screen reader? I haven't found a clear answer to this issue. On my second slide, I will have an Accessibility Lightbox. I'm attaching the first slide and would appreciate any feedback.

Thanks for your help.
