[Xerte] specific sound playing

[Restrepo Zea Céline]

Hello,

I am using Xerte toolkits and would like to know how to play specific 
parts of an audio (narration) when for example clicking on hotspot Image.
I want to do something similar to what is done in the webside 
http://www.languageguide.org/french/vocabulary/body/

With the hotspot Image activity, I can insert a narration (containing 
the different recorded words), then I can have my image with the 
pictures of the different words and the clicking zones. What I would 
like is that when a person clicks on one specific element of the 
picture, not only the text is shown but also one specific part of the 
narration to be played.

I hope I am being clear enough.

Cheers,

Céline Restrepo
