This is independent of `TextOverride`, so the visible label can stay short while the spoken label stays descriptive. The following example sets `IconOverride` and `AccessibilityLabel` together:

+Setting an explicit `AccessibilityLabel` is recommended whenever `IconOverride` is set or `TextOverride` is hidden, because screen readers would otherwise announce a generic value or no value at all. For more accessibility guidance, see [Accessibility](~/fundamentals/accessibility.md).

 All of these properties are backed by <xref:Microsoft.Maui.Controls.BindableProperty> objects, which means that the properties can be targets of data bindings. Each <xref:Microsoft.Maui.Controls.BindableProperty> has a `OneTime` binding mode, which means that data goes from the source to the target but only when the `BindingContext` changes.

+### Set the back button accessibility label
+
+Starting in .NET MAUI 11, you can set the accessibility label that screen readers (TalkBack on Android, VoiceOver on iOS and Mac Catalyst, Narrator on Windows) announce for the back button on a <xref:Microsoft.Maui.Controls.NavigationPage> navigation bar. The label is set with the `NavigationPage.BackButtonAccessibilityLabel` attached property on the page that displays the back button:
+
+```xaml
+<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
+             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
+             x:Class="MyApp.DetailPage"
+             Title="Order details"
+             NavigationPage.BackButtonAccessibilityLabel="Back to order list">
+    <!-- ... -->
+</ContentPage>
+```
+
+Setting an explicit label is recommended when the back button title is hidden, abbreviated, or shows only an icon, because screen readers would otherwise announce a generic value or no value at all. The label is independent of the `BackButtonTitle` attached property, so the visible title can stay short while the spoken label stays descriptive.

 ## Page navigation events
 
 The <xref:Microsoft.Maui.Controls.Page> class defines `NavigatedTo`, `NavigatingFrom`, and `NavigatedFrom` navigation events that are raised during page navigation. The `NavigatingFrom` event is raised when the current page is about to be navigated away from. The `NavigatedFrom` event is raised after the current page has been navigated away from. The `NavigatedTo` event is raised after navigating to the current page.
