Text to speech is not read when navigate to other screen or click on back button in Xamarin forms

Hi Guys,

I am Implemented Text to speech functionality using Xamarin forms Essentials package, Text to speech is not read when we navigate to other screen or click on back button.

I have 5 pages in my Application, suppose I am in SecondPage before reading speech content in the Second page when i navigate to third page or press back button Text to Speech is not working.

Can anyone help on this.
