Patent ID: 8055308

Claim:
A method for responding to digital vehicle requests, the method comprising: receiving a voice query at a telematics unit in a vehicle; converting the voice query to a digital signal; transmitting the digital signal from the telematics unit to a computer-end recipient at a call center node in communication with an information database, wherein the digital signal is sent to the computer-end recipient at the call center node via a digital packet data protocol over a wireless network; extracting a computer-readable command from the digital signal; executing the extracted computer-readable command at the call center node; accessing the information database based on the computer-readable command; formulating at least one response to the computer-readable command using the computer-end recipient; transmitting the at least one formulated response via the digital packet data protocol over the wireless network to the telematics unit, wherein the digital signal transmitted to the computer-end recipient and the formulated response are each compressed at different compression ratios based on whether the digital signal or formulated response is audibly played in a vehicle, and wherein when the at least one formulated response is to be audibly played in the vehicle the digital signal is compressed using a compression ratio that is at least twice the compression ratio used to compress the at least one formulated response; and translating the at least one formulated response to an analog format for playback in the vehicle.
