juste un petit commentaire

Hi Lisa, 

I have listened to the audio and the delivery is very slow so can't fault it.

I am wondering if the problem is the words melting into each other which makes them more difficult to hear on their own? 

Sylvie travaille comme infirmière 

here, the word comme makes it sound

comminfirmière

dans un hôpital ----> danZuNhopital

Hope this helps!
