I just used a button yesterday in Herndon, VA (D.C. suburbs) that had the audio crossing indicator, and actually announced the street name with a voice when the light changed. My friend commented that it would seem unlikely a blind person would be crossing there, but I have a blind friend who commutes downtown every day on the Metro. I don't know if the button does anything else, or if it was just repurposed like you describe.
