Summary of the issue:

Description of user facing changes
Reintroduces table sayAll commands.
Description of development approach
In my original PR #13956 I did a minor refactoring of SayAll classes, in order to avoid code reduplication and have a nice class inheritance. In order to achieve this I slightly rearranged calls to textInfo. This didn't affect functionality anywhere except for page turn detector in BookWorm.
Reverting to the original order of TextInfo calls at the cost of slightly less elegant code.
