1. 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.

Abstract
The invention provides a method and system for responding to digital vehicle requests. After a telematics unit receives a voice query and converts the voice query to a compressed digital signal, the signal is transmitted to a call center node. The signal is then parsed at the call center node to determine an inquiry. The call center node may then formulate at least one response to the inquiry and transmit the at least one formulated response in a digital format over the wireless network to the telematics unit. The at least one formulated response is then translated to an analog format at the telematics unit.

7. A method for responding to digital vehicle requests, comprising the steps of:
-
receiving a voice query at a telematics unit in a vehicle; converting the voice query to a digital signal; compressing the digital signal at a particular compression ratio that is established for transmitting voice queries that are not audibly reproduced; transmitting the digital signal from the telematics unit to a remote computer-end recipient via a digital cellular packet data protocol; parsing the digital signal using the computer-end recipient to determine an inquiry; formulating at least one response to the inquiry; compressing the at least one response at a compression ratio that is established for audible playback in the vehicle, which is two or more times less than the particular compression ratio; receiving a transmission of the at least one formulated response at the telematics unit via the digital cellular packet data protocol; and presenting the at least one formulated response. - View Dependent Claims (8, 9, 10, 11, 12)
