Embodiment
Below describe in detail with reference to each accompanying drawing.As long as maybe, just the identical Reference numeral of use is indicated same or analogous element in accompanying drawing and following description.Although possibly describe embodiments of the invention, modification, reorganization and other realizations are possible.For example, can replace, add or revise the element shown in the accompanying drawing, and can be through disclosed method displacement, rearrangement or interpolation stage are revised method described herein.Therefore, below detailed description does not limit the present invention.On the contrary, correct scope of the present invention is defined by appended claims.
Spoken dialog system (SDS) make people can be enough their sound and computing machine carry out alternately.The primary clustering that drives this SDS can comprise dialog manager: this assembly management and user's the session based on dialogue.Dialog manager can be confirmed user's intention through the combination of a plurality of input sources, this a plurality of input sources such as speech recognition and the output of natural language understanding assembly, the context from previous dialogue round, user's context and/or the result who returns from knowledge base (for example search engine).After confirming intention, dialog manager can be taked action, such as the dialogue that shows net result and/or continuation and user to the user to satisfy their intention.
Fig. 1 is the block diagram of operating environment 100, and operating environment 100 comprises user 105, server 107, network 120 and subscriber equipment 130.Server 107 can comprise spoken dialog system (SDS) 110, personal assistant program 112 and/or search agent 118.SDS 110 can be used for receiving user's phrase, inquiry, action and/or action request via network 120.Network 120 can comprise proprietary network (for example, corporate intranet), cellular network and/or such as public networks such as the Internets.Operating environment 100 also can comprise a plurality of data sources 150 (A)-(C).Subscriber equipment 130 can be used for providing images displayed 132, such as the image that is associated with photo, video and/or recreation.Subscriber equipment 130 can be coupled to camera 135, and camera 135 can be used for recording user 105 and catches action and/or the gesture that user 105 is done.Subscriber equipment 130 also can further be used for catching user 105 such as the word through microphone 137 oral accounts, and/or catch from user 105 such as other input through keyboard and/or mouse (not drawing).According to other embodiments of the invention, camera 135 can comprise any motion detection device that moves that can detect user 105.For example; Camera 135 can comprise Microsoft
Figure BDA0000148842180000031
motion capture device, and it comprises a plurality of cameras and a plurality of microphone.
Fig. 2 sets forth to be used for providing the method 200 of personalization of the user inquiring process flow diagram in each related summary stage according to one embodiment of the invention.Method 200 can use computing equipment 300 to realize that this will more describe in detail with reference to figure 3 below.Hereinafter the mode in each stage of implementation method 200 will be described in more detail.Method 200 can start from initial block 205 and proceed to the stage 210, and there, computing equipment 300 can receive a plurality of signals from the user.For example, SDS 110 can receive oral account inquiry and by the first performed gesture of camera 135 identifying users 105.For example, the user can wave and say an order, like " hello, xbox ".
Subsequently, method 200 can advance to the stage 220, and there, computing equipment 300 can confirm that whether this signal is to this system.For example, user 105 points to screens can comprise that is activated a gesture, and user 105 passes by before the camera 135 and can not comprise the activation gesture.According to various embodiments of the present invention, user 105 can be defined as the gesture that is associated with any gesture.If gesture that is identified and/or voice signal are identified as not to SDS 110, then method 200 can finish in the stage 270.
If signal pin is to this system, then method 200 can advance to the stage 230, and there, computing equipment 300 can be retrieved the context that is associated with Visual Display.For example, metadata can be associated with video flowing, and video flowing provides such as information such as title, performer, description, gradings.For another example, a retrieval context that can be from data source 150 (A)-(C).For example, data source 150 (A) can comprise the film information website.
Method 200 can advance to step 240 subsequently, and there, computing equipment 300 can be translated into agent actions with the signal that receives.For example, camera 135 can be caught user 105 sensing gesture, points to the subclass that gesture can be used for indicating Visual Display.For example, three famous actors are arranged in the present frame of film video, but which name in camera identifying user 105 positive senses three famous actors then.Indication can be used to create with such as " whom that performer is? " And so on the agent actions that is associated of speech polling.Therefore, agent actions can optionally identify indicated that of user in three famous actors.
Method 200 can advance to the stage 250 subsequently, and there, computing equipment 300 can be carried out agent actions according to context that is retrieved and received signal.For example, SDS 110 can be from all performers' the film that data source 150 (A) retrieval is shown tabulation, three famous actors that the result is narrowed down to when signal is received to be shown, and point to which performer according to user 105 and identify concrete performer.
Method 200 then can advance to the stage 260, and there, computing equipment 300 can show the result who is associated with performed inquiry to the user.For example, can show on subscriber equipment 130 that captions provide the result of inquiry.Subsequently, method 200 can finish in the stage 270.
