Screen Readers and Overlapping Audio

Hello! Can someone please tell me if the highlighted statement from 2020 below is still accurate? I seem to be having inconsistent results. Next, if it IS accurate, the screen reader and audio will still overlap while the screen reader reads the slide title, correct? How is this best handled, please?  (I know about variables, etc. but it seems from this article "stop audio" wouldn't be needed.)
