This property specifies whether content will be aurally rendered, and the nature of its rendering. It controls aural rendering in much the same way the 'display' property controls visual rendering.
Explicitly sets the value of this property to that of the parent.
Uses normal pronunciation rules for the current language to render content.
Suppresses/skips aural rendering of the element. No time is taken to render the element. Child elements can override this value.
