the following text is the official description of that app:

"Tired of the same old “Turn left”? Now that navigation is free in Ovi Maps you can create your own drive guidance instructions and share them with friends and family. Cheer up your loved ones’ dull morning commute or do your best pirate voice for a friend – Own Voice for Ovi Maps lets you say it your way! Own Voice for Ovi Maps requires the latest version of Ovi Maps installed on your device."
