Adding narration to Photo Story?

i'm making a photo story (program is called photo story 3 for windows) and i want to add narration to the piece..i recorded the narration on my iphone and sent it to my email then saved it on my computer..my friend said i could upload it by acting as if it was music and uploading it there..but when i click on select music and then click on the folder that has the voice memos in it they don't show up..is there anyway i can upload the voice memos??????
