Abstract

In some embodiments, systems and methods for hands-free voice-activated devices include devices that are capable of recognizing voice commands from specific users. According to some embodiments, hands-free voice-activated devices may also or alternatively be responsive to an activation identifier.

Claims

1. A method, comprising:

receiving voice input;

determining if the voice input is associated with a recognized user;

determining, in the case that the voice input is associated with the recognized user, a command associated with the voice input; and

executing the command.

2. The method of claim 1, further comprising:

initiating an activation state in the case that the voice input is associated with the recognized user.

3. The method of claim 2, further comprising:

listening, during the activation state, for voice commands provided by the recognized user.

4. The method of claim 2, further comprising:

terminating the activation state upon the occurrence of an event.

5. The method of claim 4, wherein the event includes at least one of a lapse of a time period or a receipt of a termination command.

6. The method of claim 1, further comprising:

learning to identify voice input from the recognized user.

7. The method of claim 6, wherein the learning is conducted for each of a plurality of recognized users.

8. The method of claim 1, wherein the determining the command includes:

comparing at least one portion of the voice input to a plurality of stored voice input commands.

9. The method of claim 1, wherein the determining the command includes:

interpreting a natural language of the voice input to determine the command.

10. A method, comprising:

receiving voice input;

determining if the voice input is associated with a recognized activation identifier; and

initiating an activation state in the case that the voice input is associated with the recognized activation identifier.

11. The method of claim 10, further comprising:

determining, in the case that the voice input is associated with a recognized activation identifier, a command associated with the voice input; and

executing the command.

12. The method of claim 11, wherein the determining the command includes:

comparing at least one portion of the voice input to a plurality of stored voice input commands.

13. The method of claim 11, wherein the determining the command includes:

interpreting a natural language of the voice input to determine the command.

14. The method of claim 10, wherein the activation state is only initiated in the case that the recognized activation identifier is identified as being provided by a recognized user.

15. The method of claim 10, further comprising:

listening, during the activation state, for voice commands provided by a recognized user.

16. The method of claim 15, further comprising:

learning to identify voice input from the recognized user.

17. The method of claim 16, wherein the learning is conducted for each of a plurality of recognized users.

18. The method of claim 10, further comprising:

terminating the activation state upon the occurrence of an event.

19. The method of claim 18, wherein the event includes at least one of a lapse of a time period or a receipt of a termination command.

20. A system, comprising:

a memory configured to store instructions;

a communication port; and

a processor coupled to the memory and the communication port, the processor being configured to execute the stored instructions to;

receive voice input;

determine if the voice input is associated with a recognized user;

determine, in the case that the voice input is associated with a recognized user, a command associated with the voice input; and

execute the command.
