Abstract

The invention provides a method for communicating a vehicle location information by initiating communication between a mobile communication unit and a receiving center, requesting a location information wherein the request is initiated by an automated speech recognition unit, receiving the request for vehicle information at the receiving center, receiving a vehicle location signal at the receiving center from the mobile vehicle, retrieving geographic information from a database based on the vehicle location signal, and sending the geographic information to the mobile vehicle.

Claims

1. A method for communicating a vehicle location information, comprising:

initiating communication between a mobile communication unit and a receiving center;

requesting a location information, wherein the request is initiated by an automated speech recognition unit;

receiving the request for vehicle information at the receiving center;

receiving a vehicle location signal at the receiving center from the mobile vehicle;

retrieving geographic information from a database based on the vehicle location signal; and

sending the geographic information to the mobile vehicle and wherein initiating the request for location information comprises;

providing a set of pole-zero coefficients in response to a speech signal;

providing a set of cepstral coefficients in response to the pole-zero coefficients;

providing a spectral vector in response to the cepstral coefficients; and

classifying the spectral vector and a keyword.

2. The method of claim 1, wherein the location response is sent in a predetermined format of complexity.

3. The method of claim 2 wherein the predetermined format of complexity comprises a response including one or more formats selected from the group consisting of:

a street same, a cross street name, a direction of travel, an address, an intersection, a point of interest, and a feature.

4. A computer usable medium comprising computer readable code for communicating a vehicle location information, comprising:

computer readable code for initiating communication between a mobile communication unit and a receiving center;

computer readable code for requesting a location information, wherein the request is initiated by an automated speech recognition unit;

computer readable code for receiving the request for vehicle information at the receiving center;

computer readable code for receiving a vehicle location signal at the receiving center from the mobile vehicle;

computer readable code for receiving geographic information from a database based on the vehicle location signal; and

computer readable code for sending the geographic information to the mobile vehicle and wherein computer readable code for initiating the request for location information comprises;

computer readable code for providing a set of pole-zero coefficients in response to a speech signal;

computer readable code for providing a set of cepstral coefficients in response to the pole-zero coefficients;

computer readable code for providing a spectral vector in response to the cepstral coefficients; and

computer readable code for classifying the spectral vector and keyword.
