A method and apparatus are described for providing route guidance to a user of a vehicle navigation system. A route is generated which corresponds to a plurality of maneuvers. Each of the maneuvers includes a plurality of voice fragments. Each of the voice fragments may have more than one associated audio file. Multiple audio files for the same voice fragment contain different audio output for the voice fragment. A maneuver instruction corresponding to a particular maneuver is generated by selecting audio files for each of the voice fragments in the maneuver. By providing multiple audio files for the same voice fragment and flexible selection of the multiple audio files for a maneuver instruction, route guidance communication may be improved.
