Systems and Methods for Off-Board Voice-Automated Vehicle Navigation
First Claim
1. A method of providing navigational information comprising:
- processing destination information spoken by a user of a mobile processing system;
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 mobile system user;
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 mobile system user 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 mobile processing system from the remote data center via the wireless link.

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.

10. A system for providing navigational information comprising:
-
a mobile system for processing and transmitting via a wireless link spoken requests from a mobile system user for navigational information to a selected destination; and a data center for processing the spoken requests for navigational information received via the wireless link and operable to; perform automated voice recognition processing on the spoken requests for navigational information to recognize destination components of the spoken requests; confirm the recognized destination components through interactive speech exchanges with the mobile system user via the wireless link and the mobile system; selectively allow human data center operator intervention to assist in identifying the selected recognized destination components having a recognition confidence below a selected threshold value; and download navigational information to the desired destination for transmission to the mobile system derived from the confirmed destination components. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
