Reading labels when there are none

[KatieWoe]

Test device Samsung Operating System Win 11 Browser Firefox Problem description For https://github.com/phetsims/qa/issues/961 When labels are turned off, if you listen to voicing descriptions of the shape it will still refer to the labels. Saying things like "side c-d" or "corner b" etc. Should this be reworded when such labels aren't there?

Steps to reproduce

1. Make a shape such as a trapezoid
2. Uncheck the labels box
3. Turn on voicing
4. Listen to the description of the shape
5. Click on the shape edges and corner

Thanks @KatieWoe - I don't think this is a bug, even though "Labels" are hidden visually we still need a way to identify each Vertex/Side in the speech interface.

@terracoda do you agree?

[brettfiedler]

Yeah, this was explicitly discussed during implementation. It is an atypical case, but unavoidable without inventing new names for the sides or implementing a system to denote each side by their orientation which was deemed too complex for dev time.

[terracoda]

That is correct. The labels are visually hidden to reduce screen clutter, and to meet other pedagogically scenarios in the visual design, but for the Voicing they cannot be hidden or removed. They are essential for the descriptions.
