Abstract
A method of providing navigational information comprises processing destination information spoken by a user of a mobile processing system. The processed voice information is transmitted to a remote data center. The processed voice information is analyzed at the data center to recognize components of the destination information. The center generates a list of hypothetical recognized components of the destination by confidence levels as calculated for each component of the information analyzed. The hypothetical recognized component list is displayed with confidence levels at the data center for selective checking by a human data center operator. A set of hypothetical components is selected based on confidence levels in the list. The accuracy of the selected set of hypothetical recognized components of the destination information is confirmed though interactive voice exchanges between the mobile system user and the remote data center. A destination is determined from confirmed components of the destination information.
