Abstract

The invention relates to a speech recognition assembly for acoustically controlling a function of a motor vehicle, wherein the speech recognition assembly comprises a microphone disposed in the motor vehicle for inputting a voice command, a data base disposed in the motor vehicle in which respectively at least one meaning is allocated to phonetic representations of voice commands and an on-board-speech-recognition-system disposed in the motor vehicle for determining a meaning of the voice command by use of a meaning of a phonetic representation of a voice command stored in the data base, and wherein the speech recognition assembly further comprises an off-board-speech-recognition-system disposed spatially separated from the motor vehicle for determining a meaning of the voice command.

Claims

1. Speech recognition assembly for acoustically controlling a function of a motor vehicle, wherein the speech recognition assembly comprises:

a microphone disposed in the motor vehicle for inputting a voice command;

a data base disposed in the motor vehicle in which respectively at least one meaning is allocated to phonetic representations of voice commands;

an on-board-speech-recognition-system disposed in the motor vehicle for determining a meaning of the voice command by use of a meaning of a phonetic representation of a voice command which is stored in the data base;

an off-board-speech-recognition-system disposed spatially separated from the motor vehicle for determining a meaning of the voice command; and

a communication system for transmitting a voice command from the motor vehicle to the off-board-speech-recognition-system and for transmitting

a meaning of the voice command transmitted to the off-board-speech-recognition-system, wherein the meaning was determined by the off-board-speech-recognition-system and

a meaning of the associated phonetic representation

from the off-board-speech-recognition-system to the motor vehicle, wherein the phonetic representation together with the meaning of the voice command determined by the off-board-speech-recognition-system is storable in the data base.

2. Speech recognition assembly for acoustically controlling a function of a motor vehicle, wherein the speech recognition assembly comprises:

a microphone disposed in the motor vehicle for inputting a voice command;

a data base disposed in the motor vehicle in which respectively at least one meaning is allocated to phonetic representations of voice commands;

an on-board-speech-recognition-system disposed in the motor vehicle for determining a meaning of the voice command by use of a meaning of a phonetic representation of a voice command which is stored in the data base;

an off-board-speech-recognition-system disposed spatially separated from the motor vehicle for determining a meaning of the voice command; and

a communication system for transmitting a voice command from the motor vehicle to the off-board-speech-recognition-system and for transmitting

a meaning of the voice command transmitted to the off-board-speech-recognition-system and determined by the off-board-speech-recognition-system

from the off-board-speech-recognition-system to the motor vehicle, wherein a phonetic representation associated to the meaning together with the meaning of the voice command determined by the off-board-speech-recognition-system and a position allocated to the meaning is storable in the data base.

3. Speech recognition assembly for acoustically controlling a function of a motor vehicle, wherein the speech recognition assembly comprises:

a microphone disposed in the motor vehicle for inputting a voice command;

a data base disposed in the motor vehicle in which respectively at least one meaning is allocated to phonetic representations of voice commands;

an on-board-speech-recognition-system disposed in the motor vehicle for determining a meaning of the voice command by use of a meaning of a phonetic representation of a voice command which is stored in the data base;

an off-board-speech-recognition-system disposed spatially separated from the motor vehicle for determining a meaning of the voice command; and

a communication system for transmitting the voice command from the motor vehicle to the off-board-speech-recognition-system and for transmitting

a meaning of the voice command transmitted to the off-board-speech-recognition-system which was determined by the off-board-speech-recognition-system and

a position allocated to the meaning

from the off-board-speech-recognition-system to the motor vehicle.

4. Speech recognition assembly according to claim 3, wherein the meaning of the voice command determined by the off-board-speech-recognition-system together with the position allocated to the meaning is storable in the data base.

5. Speech recognition assembly according to claim 3, wherein a phonetic representation associated to the meaning is transmittable by means of the communication system from the off-board-speech-recognition-system to the motor vehicle.

6. Speech recognition assembly according to claim 5, wherein the phonetic representation associated to the meaning together with the meaning determined by the off-board-speech-recognition-system and a position allocated to the meaning is storable in the data base.

7. Method for acoustically controlling a function of a motor vehicle, wherein the method comprises the steps of:

inputting a voice command by a microphone disposed in the motor vehicle;

attempting to determine a meaning of the voice command by means of an on-board-speech-recognition-system arranged in the motor vehicle by use of a data base arranged in the motor vehicle, wherein in the data base at least one meaning is allocated to phonetic representations of voice commands;

transmitting the voice command from the motor vehicle to an off-board-speech-recognition-system if the meaning of the voice command cannot be determined by means of the on-board-speech-recognition-system;

determining a meaning of the voice command transmitted to the off-board-speech-recognition-system by mean of the off-board-speech-recognition-system;

transmitting the meaning from the off-board-speech-recognition-system to the motor vehicle;

transmitting at least one information of the group consisting of;

a phonetic representation associated to the meaning; and

a position allocated to the meaning;

from the off-board-speech-recognition-system to the motor vehicle; and

controlling the function of the motor vehicle according to the determined meaning of the voice command.

8. Method according to claim 7, further comprising:

storing the meaning together with the phonetic representation associated to the meaning into the data base.

9. Method according to claim 7, further comprising:

storing the meaning together with the position allocated to the meaning into the data base.

10. Method according to claim 7, wherein the meaning, the phonetic representation associated to the meaning and the position allocated to the meaning are transmitted from the off-board-speech-recognition-system to the motor vehicle.

11. Method according to claim 10, further comprising:

storing the meaning together with the phonetic representation associated to the meaning and the position allocated to the meaning into the data base.

12. Motor vehicle comprising:

a microphone for inputting a voice command;

a data base in which respectively at least one meaning and a position are allocated to phonetic representations of voice commands; and

an on-board-speech-recognition-system for determining a meaning of the voice command by use of a meaning of a phonetic representation of a voice command stored in the data base.

13. Motor vehicle according to claim 12, further comprising:

an interface for a wireless access to an off-board-speech-recognition-system which is spatially separated from the motor vehicle.

14. Motor vehicle according to claim 13, wherein the phonetic representation of a voice command transmitted to the off-board-speech-recognition-system together with its meaning determined by the off-board-speech-recognition-system and a position allocated to the meaning is stored in the data base.
