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 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;
determining at the remote data center if a confidence score is below a recognition confidence value; and
if the confidence score is below the recognition confidence value, transmitting from the remote data center an automated request to have the user speak the destination information again.

Abstract
A method of providing navigational information includes the step of processing destination information spoken by a user of a mobile processing system and transmitting the processed voice information via a wireless link to a remote data center. The processed voice information is analyzed with a voice recognition system at the remote data center to recognize components of the destination information spoken by the user. The remote data center generates 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. The remote data center determines if a confidence score is below a recognition confidence value and, if the confidence score is below the recognition confidence value, transmits an automated request to have the user speak the destination information again.

12. A system for providing navigational information to a user, comprising:
-
a mobile processing system processing and transmitting via a wireless link spoken requests from a user for navigational information to a selected destination; and a data center processing the spoken requests for navigational information received via the wireless link and; performing automated voice recognition analysis on the spoken requests for navigational information to recognize destination components of the spoken requests; generating 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; determining if a confidence score is below a recognition confidence value; and if the confidence score is below the recognition confidence value, transmitting from the remote data center an automated request to have the user speak the destination information again. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
