Hi Isabel,

You could make each one a toggle button using <button>. But don't use aria-pressed if any of your users are using IE11 (which still includes most JAWS users) because IE doesn't support aria-pressed correctly. This is a pity because aria-pressed has the semantics to allow AT to report the current state and any change in state, but that doesn't happen in IE (with either JAWS or NVDA).

You can easily create a toggle button without aria-pressed by changing the button's name when its state changes to indicate the new action, e.g. from "select French" to "unslect French". Make sure the button name is an action, not the state, because button names are always actions. Provide feedback to screen reader users using aria-live, e.g. "French is selected" or "You selected French". The button would need to have the additional action of changing the status of the currently 'selected' button in the group (if there is one) to 'unselected'. You'll need to inform users up front that the group only allows one selection so that they know this will happen. If you still feel it may not be clear, consider adding information about the additional action to the screen reader feedback, e.g. "French selected and German unselected".

And don't make them look like standard radio buttons because otherwise users will think they are standard radio buttons.
