How the heck do you make a website braille? And most browsers have text-to-speech capabilities built in.
“I’m from the government, and I’m here to help you.” Even a blind-from-birth person can see through that lie.
If the text is sent as text. If it is embedded in images the text-to-speech won't read it.
I'm trying to think of what a bricks and mortar grocery store does for the blind? The products don't have braille on them and the signs on the shelves don't either. Maybe the ADA requires that a store employee helps the blind shopper which isn't an option on a website.
Its expensive. It has to do with the coding of the site, so that the conversion tools can read it. So pictures will have a description and every cell has a label.
