Abstract

A system and method for an integrated, multi-modal, multi-device natural language voice services environment may be provided. In particular, the environment may include a plurality of voice-enabled devices each having intent determination capabilities for processing multi-modal natural language utterances in addition to knowledge of the intent determination capabilities of other devices in the environment. Further, the environment may be arranged in a centralized manner, a distributed peer-to-peer manner, or various combinations thereof. As such, the various devices may cooperate to determine intent of multi-modal natural language utterances, and commands, queries, or other requests may be routed to one or more of the devices best suited to take action in response thereto.

Claims

1. A method of providing an integrated natural language voice services environment comprising one or more of an input device that receives a natural language utterance, a first device, or one or more secondary devices, the method being implemented in the first device having one or more physical processors programmed with computer program instructions that, when executed by the one or more physical processors, program the first device to perform the method, the method comprising:

obtaining, by the first device from the input device, the natural language utterance;

transcribing, by the first device, the natural language utterance;

determining, by the first device, a preliminary intent prediction of the natural language utterance based on the transcribing; and

invoking, by the first device, at least one action at one or more of the input device, the first device, or the one or more secondary devices based on the preliminary intent prediction.

2. The method of claim 1, wherein invoking the at least one action at one or more of the input device, the first device, or the one or more secondary devices comprises transmitting a request related to the natural language utterance based on the preliminary intent prediction.

3. The method of claim 1, wherein the one or more secondary devices include at least a second device, the method further comprising:

transmitting, by the first device, the natural language utterance to the second device;

receiving, by the first device from the second device, a second intent prediction of the natural language utterance; and

determining, by the first device, an intent of the natural language utterance based on the preliminary intent prediction and the second intent prediction, wherein the at least one action is invoked based on the determined intent.

4. The method of claim 3, the method further comprising:

determining, by the first device, processing capabilities associated with the one or more secondary devices; and

selecting, by the first device, based on the processing capabilities associated with the one or more secondary devices, the second device to make the second intent prediction of the natural language utterance.

5. The method of claim 4, the method further comprising:

maintaining, by the first device, a constellation model that describes natural language resources, dynamic states, and intent determination capabilities associated with the input device and the one or more secondary devices, wherein the processing capabilities associated with the one or more secondary devices are determined based on the constellation model.

6. The method of claim 5, wherein the intent determination capabilities for a given one of the input device, the first device, or the one or more secondary devices are based on at least one of processing power, storage resources, natural language processing capabilities, or local knowledge.

7. The method of claim 3, the method further comprising:

determining, by the first device, a domain relating to the natural language utterance; and

selecting, by the first device, based on the domain, the second device to make the second intent prediction of the natural language utterance.

8. The method of claim 7, wherein the one or more secondary devices are associated with different domains, the second device is associated with the domain, and the different domains comprise the domain.

9. The method of claim 1, the method further comprising:

communicating, by the first device, the natural language utterance to each of the one or more secondary devices, wherein each of the one or more secondary devices determine an intent of the natural language utterance received at the input device using local intent determination capabilities;

receiving, by the first device, the intent determined by each of the secondary devices; and

arbitrating, by the first device, among the intent determinations of the secondary devices to determine the intent of the natural language utterance, wherein the at least one action is invoked based on the arbitrated intent determinations.

10. The method of claim 1, wherein the input device initially received the natural language utterance.

11. A system for processing a natural language utterance in an integrated natural language voice services environment comprising a plurality of devices configured to connect to each other, the system comprising:

an input device that receives the natural language utterance;

one or more secondary devices; and

a first device having one or more physical processors programmed with computer program instructions that, when executed by the one or more physical processors, program the first device to;

obtain, from the input device, the natural language utterance;

transcribe the natural language utterance;

determine a preliminary intent prediction of the natural language utterance based on the transcription; and

invoke at least one action at one or more of the input device, the first device, or the one or more secondary devices based on the preliminary intent prediction.

12. The system of claim 11, wherein to invoke the at least one action at one or more of the input device, the first device, or the one or more secondary devices, the first device is further programmed to:

transmit a request related to the natural language utterance based on the preliminary intent prediction.

13. The system of claim 11, wherein the one or more secondary devices include at least a second device, and wherein the first device is further programmed to:

transmit the natural language utterance to the second device;

receive, from the second device, a second intent prediction of the natural language utterance; and

determine an intent of the natural language utterance based on the preliminary intent prediction and the second intent prediction, wherein the at least one action is invoked based on the determined intent.

14. The system of claim 13, wherein the first device is further programmed to:

determine processing capabilities associated with the one or more secondary devices; and

select based on the processing capabilities associated with the one or more secondary devices, the second device to make the second intent prediction of the natural language utterance.

15. The system of claim 14, wherein the first device is further programmed to:

maintain a constellation model that describes natural language resources, dynamic states, and intent determination capabilities associated with the input device and the one or more secondary devices, wherein the processing capabilities associated with the one or more secondary devices are determined based on the constellation model.

16. The system of claim 15, wherein the intent determination capabilities for a given one of the input device, the first device, or the one or more secondary devices are based on at least one of processing power, storage resources, natural language processing capabilities, or local knowledge.

17. The system of claim 13, wherein the first device is further programmed to:

determine a domain relating to the natural language utterance; and

select, based on the domain, the second device to make the second intent prediction of the natural language utterance.

18. The system of claim 17, wherein the one or more secondary devices are associated with different domains, the second device is associated with the domain, and the different domains comprise the domain.

19. The system of claim 11, wherein the first device is further programmed to:

communicate the natural language utterance to each of the one or more secondary devices, wherein each of the one or more secondary devices determine an intent of the natural language utterance received at the input device using local intent determination capabilities;

receive the intent determined by each of the secondary devices; and

arbitrate among the intent determinations of the secondary devices to determine the intent of the natural language utterance, wherein the at least one action is invoked based on the arbitrated intent determinations.
