Method and system for controlling an in-vehicle CD player
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.

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;

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.
