The PlayStation 4 is shipped with a few accessibility features such as the Magnifier and Text-to-Speech capability, which are meant to make the console easier to use. You can enable the accessibility features by going into Settings > Accessibility, but there's an easier and hassle-free method.
This tutorial will teach how to add the Accessibility Settings to the Quick menu.
Access PS4 Accessibility Settings from the Quick Menu
Go to Settings > Accessibility and tick the Add to Quick Menu checkbox.
Moving forward, you will be able to access the accessibility features by holding down the PS button of the DualShock 4 Controller for a couple of seconds, and selecting Accessibility Settings from the Quick Menu.
