Read current page title with screen reader when push/pop a page - xamarin.forms

Question

I'm developing an app for blind or visually impaired people using Xamarin.Forms. I have a NavigationPage with the title X, and when the app starts talkback reads the title X. I have 4 pages that can be navigated to with A, B, C and D titles. I would like that when navigating through different pages, the screen reader would read the title of the page. Is it possible?
For example, if I switch on talkback on Android and I navigate through settings pages, talkback reads all page titles. I want to do something similar.

Read current page title with screen reader when push/pop a page
You could use DependencyService to achieve the feature on each platform and call the function code in the OnAppearing method of each page.
Check the code:
Create an interface in the shared project.
public interface IAccessibilityManager
{
void sendAccessibility(string speakText);
}
Implement the interface in the required platform projects.
[assembly: Dependency(typeof(DroidAccessibilityImplement))]
namespace App19F_9.Droid
{
public class DroidAccessibilityImplement : IAccessibilityManager
{
public void sendAccessibility(string speakContent)
{
AccessibilityManager manager = (AccessibilityManager)Android.App.Application.Context.GetSystemService(Context.AccessibilityService);
if (manager.IsEnabled)
{
AccessibilityEvent _event = AccessibilityEvent.Obtain();
_event.EventType = EventTypes.Announcement;
_event.Text.Add(new Java.Lang.String(speakContent));
manager.SendAccessibilityEvent(_event);
}
}
}
}
Resolve the platform implementations from shared code.
public partial class Page5 : ContentPage
{
...
protected override void OnAppearing()
{
base.OnAppearing();
DependencyService.Get<IAccessibilityManager>().sendAccessibility(this.Title);
}
}
