You have a 1 after Name, but you don't after Text.
Also, all sound files for diaries go in:

redist\lang\eng\voices\diaries

You have them sort of correct, but try moving them from the "fake" directory in your custom story folder to the real one in the redist.

If none of that helps, could you post your full lang file?
