# has-valid-accessibility-live-region
On android devices, when components dynamically change, we want TalkBack to alert the end user. This is made possible by the `accessibilityLiveRegion` property. It can be set to the following values:
- `"none"`: Accessibility services should not announce changes to this view.
- `"polite"`: Accessibility services should announce changes to this view.
- `"assertive"`: Accessibility services should interrupt ongoing speech to immediately announce changes to this view.
