Abstract
A method of providing navigational information includes processing destination information spoken by a mobile processing system user. The processed voice information is transmitted to a remote center wirelessly. The processed voice information is voice recognition analyzed to recognize components of die destination information spoken. The remote center generates a list of hypothetical recognized components of the destination information listed by confidence levels. The list of hypothetical recognized components is displayed with confidence levels at the remote center for selective checking by a human data center operator. A component set is selected based on the confidence levels and accuracy of the selected set is confirmed by interactive voice exchanges. A destination is determined from confirmed components of the destination information. Route information to the destination is generated at the remote center and the route information is transmitted wirelessly to the mobile processing system from the remote center.
