Accessible text based on a variable

I have a resource that has 3 possible languages (English, Welsh and Polish). To avoid having 3 of every slide, I've set each object on each slide to have different states, one for each language. These states are chosen via true/false variables.

The issue I'm having now is with the accessible text labels. I'd like it so that the label is set/changes based on which of the 3 language variables are set to true. Does anyone have any ideas how this could be done? Maybe something with javascript?
