Abstract
A system for providing navigational information comprises a mobile system processing and transmitting via a wireless link a continuous voice stream spoken by a user of the mobile system, the continuous voice stream including a complete destination address and a data center processing the continuous voice stream received via the wireless link into voice navigational information. The data center performs automated voice recognition processing on the voice navigational information to recognize destination components of the complete destination address, confirms the recognized destination components through interactive speech exchanges with the mobile system user via the wireless link and the mobile system, selectively allows human data center operator intervention to assist in identifying the selected recognized destination components having a recognition confidence below a selected threshold value, and downloads the complete destination address for transmission to the mobile system derived from the confirmed recognized destination components.
