Speech Notes
The virtual screen reader used in this site's demos and real screen readers (NVDA, VoiceOver, JAWS, etc.) don't always announce things the same way. This section lists known differences related to this role.
N control(s)- Real screen readers rarely announce this. NVDA / VoiceOver do not announce aria-controls, and JAWS has it off by default since 2019. Safe to ignore.
