Impress: how to play one of several sounds on click

I have several sound clips demonstrating pronunciations that I want to put on a slide. I do NOT want the sounds to all just play when I open the slide, only when I click on them.

Any way to do that?

Suggest you form a first slide without sound. Duplicate that slide, and set no transition time, so that on a click as the second slide appears no transition is visible to the eye, and add the first sound to that second slide. Duplicating that first side several times and adding a different sound to each successively should give you the desired result.
