Playlists with windows media player

Dear sir,

In our project we give the voice to the system.Then the relevant text 
for those spoken words are written in a text file.By reading those 
characters one by one from those words in the text file, images are 
displayed in a windows media player using .avi files.

1) We want to make a play list according to the input voice at that 
time(the time voice is given).When another voice is coming, previous play 
list should be dissapeared.

2) We want to handle the replay also in windows media player.
 

Thankyou.
