Gets or sets if the LiveRegionChanged events should be restricted with respect to how frequently they are sent when the LiveText changes. The default value is false, i.e. by default one LiveRegionChanged event will be raised for every LiveText change even if multiple LiveText changes occur per second. When this setting is enabled, the value of Frequency controls how frequently the LiveRegionChanged event is raised.

Remarks
This property is useful for LiveTextBlocks whose LiveText can change multiple times per second. Rapidly occurring LiveRegionChanged events can cause screen readers to read the same LiveText multiple times due to how automation events are handled in Windows.
