Voice guide navigation files

[OfficerJJ]

What is the file format for voice guide files? Since Nokia Own Voice is not available for my phone i would like to record them on my own

Actually if you check the voice files, I suppose you could maybe try replacing the actual audio files. However there are textual files as well, but as those ones clearly indicate the copyright information, and say that any re-distributions etc are prohibited, you might just want to have a look into them and then contact the entity mentioned in them for any information on how you could use the files.
