1. A method of providing navigational information to a vehicle occupant comprising:

  • processing destination information spoken by a vehicle occupant with an on-board processing system on a vehicle;

    transmitting the processed voice information via a wireless link to a remote data center;

    analyzing the processed voice information with a computerized voice recognition system at the remote data center to recognize components of the destination information spoken by the vehicle occupant;

    computer-generating at the remote data center a list of hypothetical recognized components of the destination information listed by confidence levels as computer-calculated for each component of the destination information analyzed by the voice recognition system;

    computer-generating a display of the computer-generated list of hypothetical recognized components and confidence levels at the remote data center for selective checking by a human data center operator;

    selecting a set of hypothetical components based on the confidence levels in the list;

    confirming the accuracy of the selected set of hypothetical recognized components of the destination information via computer-generated interactive exchanges between the vehicle occupant and the remote data center; and

    determining a destination from confirmed components of the destination information.
