in response to a third voice input received from the user device in response to the combined dialog response, updating a state of both the first dialog and the second dialog.

6. The method of claim 1 , wherein each suggested dialog response of the first plurality of suggested dialog responses is scored, and wherein the particular dialog corresponding to the first task is determined based on the scoring.

7. The method of claim 1 , further comprising receiving, from the first data provider, a non-augmented response that ignores the suggested dialog response of the second data provider.

8. The method of claim 1 , wherein:

each dialog response of the first plurality of suggested dialog responses includes a respective confidence score provided by a respective data provider of the plurality of data providers; and

the one or more first dialog responses in the corresponding first dialog are selected based on the respective confidence scores.

9. A dialog system comprising:

a user device; and

one or more computers configured to interact with the user device and to perform operations comprising:

receiving at the dialog system a request, from the user device, associated with performance of a first task, wherein the request comprises a first voice input of a user of the user device;

submitting the request to each of a plurality of distinct data providers, wherein each data provider is associated with a distinct data model configured to interpret particular types of voice inputs;

in response to the first voice input, receiving a first plurality of suggested dialog responses to the first voice input from two or more of the data providers;

determining, from the first plurality of suggested dialog responses, a dialog intent of the first voice input and a corresponding first dialog for the first task including one or more first dialog responses to provide to the user device to complete the first dialog for the first task;

receiving at the dialog system a second voice input in response to providing the one or more first dialog responses to the user and submitting the second voice input to each of the plurality of data providers;

receiving a second plurality of suggested dialog responses to the second voice input from two or more of the data providers;

in response to one of the second plurality of suggested dialog responses of a second data provider, receiving, from a first data provider, an augmented response that includes a modification or addition based on a disambiguation of an entity, the disambiguation of the entity being included in the suggested dialog response that is provided by the second data provider; and

determining a second dialog response including determining a combined response including the suggested dialog response of the second data provider and the augmented response of the first data provider and providing the combined response to the user device.

10. The system of claim 9 , wherein the one or more computers are configured to perform operations comprising:

updating a state of the first dialog in response to the one or more first dialog responses to the first voice input; and

providing the updated state to the plurality of data providers as context for analyzing the second voice input.

11. The system of claim 9 , wherein the first dialog is generated by a first data provider and the second dialog is generated by a second data provider of the plurality of data providers.

12. The system of claim 9 , wherein the one or more computers are configured to perform operations comprising:

combining a dialog response from a first data provider and a second data provider to provide to the user device, wherein the combined dialog response is associated with the first task and with a second task determined from the second voice input.

13. The system of claim 12 , wherein the one or more computers are configured to perform operations comprising:

in response to a third voice input received from the user device in response to the combined dialog response, updating a state of both the first dialog and the second dialog.

14. The system of claim 9 , wherein each suggested dialog response of the first plurality of suggested dialog responses is scored, and wherein the particular dialog corresponding to the first task is determined based on the scoring.

15. One or more non-transitory computer storage media encoded with computer program instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:

receiving at a dialog system a request, from a user device, associated with performance of a first task, wherein the request comprises a first voice input of a user of the user device;

submitting the request to each of a plurality of distinct data providers, wherein each data provider is associated with a distinct data model configured to interpret particular types of voice inputs;

in response to the first voice input, receiving a first plurality of suggested dialog responses to the first voice input from two or more of the data providers;

determining, from the first plurality of suggested dialog responses, a dialog intent of the first voice input and a corresponding first dialog for the first task including one or more first dialog responses to provide to the user device to complete the first dialog for the first task;

receiving at the dialog system a second voice input in response to providing the one or more first dialog responses to the user and submitting the second voice input to each of the plurality of data providers;

receiving a second plurality of suggested dialog responses to the second voice input from two or more of the data providers;

in response to one of the second plurality of suggested dialog responses of a second data provider, receiving, from a first data provider, an augmented response that includes a modification or addition based on a disambiguation of an entity, the disambiguation of the entity being included in the suggested dialog response that is provided by the second data provider; and

determining a second dialog response including determining a combined response including the suggested dialog response of the second data provider and the augmented response of the first data provider and providing the combined response to the user device.

16. The one or more non-transitory computer storage media of claim 15 , comprising computer program instructions that when executed by the one or more computers cause the one or more computers to perform operations comprising:

updating a state of the first dialog in response to the one or more first dialog responses to the first voice input; and

providing the updated state to the plurality of data providers as context for analyzing the second voice input.

17. The one or more non-transitory computer storage media of claim 15 , wherein the first dialog is generated by a first data provider and the second dialog is generated by a second data provider of the plurality of data providers.

18. The one or more non-transitory computer storage media of claim 15 , further comprising computer program instructions that when executed by the one or more computers cause the one or more computers to perform operations comprising:

combining a dialog response from a first data provider and a second data provider to provide to the user device, wherein the combined dialog response is associated with the first task and with a second task determined from the second voice input.

19. The one or more non-transitory computer storage media of claim 18 , further comprising computer program instructions that when executed by the one or more computers cause the one or more computers to perform operations comprising:
