in accordance with a determination that the first voice input corresponds to a first occupant of the plurality of occupants, authenticating the first occupant, and presenting at the electronic device a response; and

in accordance with a determination that the first voice input corresponds to none of the plurality of occupants: restricting functionality of the electronic device.

11. The device of claim 10 , wherein the request is a request for personal information, the response includes the requested personal information with respect to the first occupant, and restricting functionality of the electronic device comprises acting on only requests that involve non-personal information.

12. The device of claim 11 , comprising instructions for:

determining the request based on the first voice input; and

generating the response in accordance with the determined request.

13. The device of claim 12 , wherein:

the determined request includes a request to the electronic device to awaken; and

the response includes an audible greeting, wherein the greeting includes an indication of an identity of the determined first occupant.

14. The device of claim 12 , wherein:

the personal information includes an email, a calendar event, or a bank balance; and

the device comprises instructions for:

obtaining the requested personal information with respect to the first occupant.

15. The device of claim 14 , comprising instructions for:

16. A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which, when executed by an electronic device being configured to present information to a plurality of occupants and having one or more microphones, a speaker, and one or more processors, cause the electronic device to perform operations comprising:

receiving a first voice input associated with a request;

in response to receiving the first voice input, accessing one or more voice models each trained to a different one of the plurality of occupants;

comparing the first voice input to the one or more voice models;

based on the comparing, determining whether the first voice input corresponds to any of the plurality of occupants;

in accordance with a determination that the first voice input corresponds to a first occupant of the plurality of occupants, authenticating the first occupant, and presenting at the electronic device a response; and

in accordance with a determination that the first voice input corresponds to none of the plurality of occupants: restricting functionality of the electronic device.

17. The computer readable storage medium of claim 16 , wherein the request is a request for personal information, the response includes the requested personal information with respect to the first occupant, and restricting functionality of the electronic device comprises acting on only requests that involve non-personal information.

18. The computer readable storage medium of claim 17 , further comprising instructions which, when executed by the electronic device, cause the electronic device to perform operations comprising:

receiving a second voice input;

comparing the second voice input to the one or more voice models;
