Abstract

The present invention provides a method for controlling a compact disc player in a telematics equipped mobile vehicle that includes receiving CD data, from at least one compact disc, and analog input at the telematics unit. The method further includes producing a metadata file based on the received CD data, producing a speech recognition grammar file based on the metadata file, producing a dialog command based on the received analog input, and controlling the compact disc player in the telematics equipped mobile vehicle responsive to a control command. The control command is based on the speech recognition grammar file and the dialog command. The metadata is selected from one or more members of a group including: disc title, artist name, song title, disc number, and track number.

Claims

1. A method for controlling a compact disc player in a telematics equipped mobile vehicle, the method comprising:

receiving CD data and analog input at the telematics unit, the CD data received from at least one compact disc;

producing a metadata file based on the received CD data;

producing a speech recognition grammar file based on the metadata file;

producing a dialog command based on the received analog input; and

controlling the compact disc player in the telematics equipped mobile vehicle responsive to a control command, the control command based on the speech recognition grammar file and the dialog command.

2. The method of claim 1, wherein receiving CD data at the telematics unit comprises:

querying each of the compact discs for CD data; and

transferring the CD data to the telematics unit.

3. The method of claim 1, wherein the metadata is selected from one or more members of the group consisting of:

disc title, artist name, song title, disc number, and track number.

4. The method of claim 1, wherein producing the metadata file based on the received CD data comprises:

analyzing the CD data with music recognition software;

identifying metadata within the CD data; and

generating the metadata file.

5. The method of claim 1, wherein producing the speech recognition grammar file based on the metadata file comprises:

analyzing the metadata file with speech recognition software;

identifying speech recognition grammar within the metadata; and

generating the speech recognition grammar file.

6. The method of claim 5, further comprising:

transferring the generated speech recognition grammar file to an ASR engine having a dynamic grammar control mechanism.

7. The method of claim 1, wherein controlling the compact disc player comprises:

comparing the dialog command with the speech recognition grammar file;

determining a control command based on the comparison; and

implementing the control command.

8. The method of claim 1, further comprising:

establishing a wireless data connection between the telematics equipped mobile vehicle and a call center;

sending the CD data to a call center; and

receiving the metadata file at the telematics equipped mobile vehicle.

9. The method of claim 1, further comprising:

establishing a wireless data connection between the telematics equipped mobile vehicle and a call center;

sending the CD data to a call center;

sending the analog input to the call center; and

receiving the speech recognition grammar file and the dialog command at the telematics equipped mobile vehicle.

10. The method of claim 1, further comprising:

establishing a wireless data connection between the telematics equipped mobile vehicle and a call center;

sending the CD data to a call center;

sending the analog input to the call center;

producing the control command at the call center; and

receiving the control command at the telematics equipped mobile vehicle.

11. The method of claim 10, wherein producing the control command comprises:

comparing the dialog command with the speech recognition grammar file at the call center; and

determining the control command based on the comparison at the call center.

12. A computer readable medium for controlling a compact disc player in a telematics equipped mobile vehicle, comprising:

computer readable code for receiving CD data and analog input at the telematics unit, the CD data received from at least one compact disc;

computer readable code for producing a metadata file based on the received CD data;

computer readable code for producing a speech recognition grammar file based on the metadata file;

computer readable code for producing a dialog command based on received analog input; and

computer readable code for controlling the compact disc player in the telematics equipped mobile vehicle responsive to a control command, the control command based on the speech recognition grammar file and the dialog command.

13. The computer readable medium of claim 12, wherein the computer readable code for receiving CD data at the telematics unit comprises:

computer readable code for querying each of the compact discs for CD data; and

computer readable code for transferring the CD data to the telematics unit.

14. The computer readable medium of claim 12, wherein the metadata is selected from one or more members of the group consisting of:

disc title, artist name, song title, disc number, and track number.

15. The computer readable medium of claim 12, wherein the computer readable code for producing the metadata file based on the CD data comprises:

computer readable code for analyzing the CD data with music recognition software;

computer readable code for identifying metadata within the CD data; and

computer readable code for generating the metadata file.

16. The computer readable medium of claim 12, wherein the computer readable code for producing the speech recognition grammar file based on the metadata file comprises:

computer readable code for analyzing the metadata file with speech recognition software;

computer readable code for identifying speech recognition grammar within the metadata; and

computer readable code for generating the speech recognition grammar file.

17. The computer readable medium of claim 16, further comprising:

computer readable code for transferring the generated speech recognition grammar file to an ASR engine having a dynamic grammar control mechanism.

18. The computer readable medium of claim 12, wherein the computer readable code for controlling the compact disc player comprises:

computer readable code for comparing the dialog command with the speech recognition grammar file;

computer readable code for determining a control command based on the comparison; and

computer readable code for implementing the control command.

19. The computer readable medium of claim 12, further comprising:

computer readable code for establishing a wireless data connection between the telematics equipped mobile vehicle and a call center;

computer readable code for sending the CD data to a call center; and

computer readable code for receiving metadata file at the telematics equipped mobile vehicle.

20. The computer readable medium of claim 12, further comprising:

computer readable code for establishing a wireless data connection between the telematics equipped mobile vehicle and a call center;

computer readable code for sending the CD data to a call center;

computer readable code for sending the dialog command to the call center; and

computer readable code for receiving the speech recognition grammar file and the dialog command at the telematics equipped mobile vehicle.

21. The computer readable medium of claim 12, further comprising:

computer readable code for establishing a wireless data connection between the telematics equipped mobile vehicle and a call center;

computer readable code for sending the CD data to a call center;

computer readable code for sending the analog input to the call center;

computer readable code for producing the control command at the call center; and

computer readable code for receiving the control command at the telematics equipped mobile vehicle.

22. The computer readable medium of claim 21, wherein the computer readable code for producing the control command comprises:

computer readable code for comparing the dialog command with the speech recognition grammar file at the call center; and

computer readable code for determining the control command based on the comparison at the call center.
