I'm using NSAccessibilityAnnouncementRequestedNotification with NSAccessibilityPriorityMedium to announce incoming, unsolicited text in a text game - and sometimes VoiceOver will move onto the next message without fully reading out the first.
How can I get VoiceOver to fully read out the current message before moving onto the next?
I'm building this accessibility work as part of Mudlet (mudlet.org) an open-source MUD client to give more context.
