Screen reader support is a basic necessity that Roblox should already support. It helps visually impaired or dyslexic people understand dialogue in story-driven games. I believe this should be added to help accessibility for people who have trouble reading.
Ideally, the feature should come as new properties on all GuiObjects, with “Readable” or “AllowScreenReading” acting as a bool to toggle the feature on/off, and an “AltText” string, which is what the screen reader will pick up. The purpose of this string will allow ImageLabels and ImageButtons to be read out, and leaving the string empty for TextLabels and TextButtons will read the “Text” property.
