Hi, I have a web app running on a webos 2018 TV. It is enhanced with aria-labels and such so that a screen reader should synthesize speech from the focused elements. I have turned on voice assistance of course. On another well known platform I have speech, but on this system it is silent. I know I can make it speak using webos API, but for now I'm looking for this screen reader approach. Is there anything I can do to enable it?
