You should add an AXValueDescription attribute to your slider.
The best way is to make a subclass of the slider cell.
The Sketch+Accessibility example has sample code for how to do this:

Look for the class SKTPixelSliderCell. The code shows you what you would need to do. Then, in IB, set the type of slider cell to be your custom subclass.
