Abstract:
1. A method of providing navigational information to a vehicle driver comprising: processing destination information spoken by a vehicle driver 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 voice recognition system at the remote data center to recognize components of the destination information spoken by the vehicle driver; generating at the remote data center a list of hypothetical recognized components of the destination information listed by confidence levels as calculated for each component of the destination information analyzed by the voice recognition system; displaying the 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 interactive voice exchanges between the vehicle driver and the remote data center; determining a destination from confirmed components of the destination information; generating route information to the destination at the remote data center; and transmitting the route information to the on-board processing system from the remote data center via the wireless link.
