Abstract

A voice-responsive building management system is described herein. One system includes an interface, a dynamic grammar builder, and a speech processing engine. The interface is configured to receive a speech card of a user, wherein the speech card of the user includes speech training data of the user and domain vocabulary for applications of the building management system for which the user is authorized. The dynamic grammar builder is configured to generate grammar from a building information model of the building management system. The speech processing engine is configured to receive a voice command or voice query from the user, and execute the voice command or voice query using the speech training data of the user, the domain vocabulary, and the grammar generated from the building information model.

Claims

1. A voice-responsive building management system, comprising:

an interface configured to receive a speech card of a user, wherein the speech card of the user includes;

speech training data of the user; and

domain vocabulary for applications of the building management system for which the user is authorized;

a dynamic grammar builder configured to generate grammar from a building information model of the building management system; and

a speech processing engine configured to;

receive a voice command or voice query from the user; and

execute the voice command or voice query using the speech training data of the user, the domain vocabulary, and the grammar generated from the building information model.

2. The system of claim 1, wherein:

the dynamic grammar builder is configured to generate grammar from project configuration data associated with the building management system; and

the speech processing engine is configured to execute the voice command or voice query using the grammar generated from the project configuration data.

3. The system of claim 2, wherein the project configuration data is pre-loaded into the building management system during installation of the building management system.

4. The system of claim 1, wherein:

the dynamic grammar builder is configured to generate grammar from controller configuration data associated with the building management system; and

the speech processing engine is configured to execute the voice command or voice query using the grammar generated from the controller configuration data.

5. The system of claim 4, wherein the controller configuration data is dynamically loaded into the building management system during runtime of the building management system.

6. The system of claim 1, wherein:

the dynamic grammar builder is configured to generate grammar from runtime data associated with the building management system; and

the speech processing engine is configured to execute the voice command or voice query using the grammar generated from the runtime data.

7. The system of claim 1, wherein the building information model is a three-dimensional building information model.

8. A computer implemented method for operating a voice-responsive building management system, comprising:

receiving speech training data of a user and domain vocabulary for applications of the building management system for which the user is authorized;

generating grammar from a building information model of the building management system;

receiving a voice command or voice query from the user; and

executing the voice command or voice query using the speech training data of the user, the domain vocabulary, and the grammar generated from the building information model.

9. The method of claim 8, wherein the method includes receiving the speech training data of the user and the domain vocabulary from a speech card issued to the user.

10. The method of claim 8, wherein the method includes receiving the speech training data of the user from a cloud-based computing system.

11. The method of claim 8, wherein executing the voice command or voice query includes displaying information associated with the voice command or voice query to the user.

12. The method of claim 8, wherein executing the voice command or voice query includes providing a voice response with information associated with the voice command or voice query to the user.

13. The method of claim 8, wherein:

the voice command or voice query includes a particular item associated with the building management system; and

executing the voice command or voice query includes displaying the particular item and data associated with the particular item.

14. The method of claim 8, wherein:

the voice command or voice query includes a particular item associated with the building management system; and

executing the voice command or voice query includes providing a voice response with data associated with the particular item.

15. The method of claim 8, wherein the method is performed without using the internet.

20. The system of claim 15, wherein the speech card is encrypted such that only the applications of the building management system for which the user is authorized can decrypt and use the speech card.

16. A voice-responsive building management system, comprising:

a speech card having speech training data of a user and domain vocabulary for applications of the building management system for which the user is authorized;

an interface configured to receive the speech card;

a dynamic grammar builder configured to generate grammar from a building information model of the building management system; and

a speech processing engine configured to;

receive a voice command or voice query from the user; and

execute the voice command or voice query using the speech training data of the user, the domain vocabulary, and the grammar generated from the building information model.

17. The system of claim 16, wherein the speech training data of the user includes speaker voice variations associated with the user.

18. The system of claim 16, wherein the domain vocabulary includes:

a pronunciation lexicon for the user and the applications of the building management system for which the user is authorized; and

grammar recognition for the user and the applications of the building management system for which the user is authorized.

19. The system of claim 16, wherein:

the speech card includes a speech password; and

the speech card includes details of the user.
