I have noticed when I use do not disturb with the latest iOS on iPhone 5, sometimes voiceOver will speak alerts for calls. I can't remember if texts are read, I have times where it works just as I expect it, but sometimes when I really don't want to be disturbed, I get the alerts, but no ringtone. Has anybody else experienced this? I am concerned it will do it in a meeting or some other important event. Fortunately that has not happened, the most inconvenient time was when I was unwell a few weeks ago and I didn't want to get up to answer, so fortunately I didn't have to worry about anyone else hearing the alert messages from VoiceOver.
