According to one embodiment, the planner module (225) can determine a plurality of domains necessary to perform a task based on the determined intent. The planner module (225) can determine a plurality of operations included in each of the plurality of domains determined based on the intent. According to one embodiment, the planner module (225) can determine parameters necessary to execute the determined plurality of operations or result values ​​output by the execution of the plurality of operations. The parameters and the result values ​​can be defined as concepts of a specified format (or class). Accordingly, the plan can include a plurality of operations and a plurality of concepts determined by the user's intent. The planner module (225) can determine the relationships between the plurality of operations and the plurality of concepts in a stepwise (or hierarchical) manner. For example, the planner module (225) can determine the execution order of a plurality of actions based on the user's intention, based on a plurality of concepts. In other words, the planner module (225) can determine the execution order of a plurality of actions based on parameters required for the execution of the plurality of actions and results output by the execution of the plurality of actions. Accordingly, the planner module (225) can generate a plan including association information (e.g., ontology) between a plurality of actions and a plurality of concepts. The planner module (225) can generate the plan using information stored in a capsule database (230) in which a set of relationships between concepts and actions is stored.

[0065] The natural language generation module (227) of one embodiment can convert specified information into text format. The information converted into text format may be in the form of natural language speech. The text-to-speech conversion module (229) of one embodiment can convert information in text format into information in speech format.

[0066] According to one embodiment, some or all of the functions of the natural language platform (220) may also be implemented in the electronic device (201).

[0067] The capsule database (230) may store information on the relationships between a plurality of concepts and actions corresponding to a plurality of domains. According to one embodiment, a capsule may include a plurality of action objects (or action information) and concept objects (or concept information) included in a plan. According to one embodiment, the capsule database (230) may store a plurality of capsules in the form of a concept action network (CAN). According to one embodiment, the plurality of capsules may be stored in a function registry included in the capsule database (230).

[0068] The capsule database (230) may include a strategy registry that stores strategy information necessary for determining a plan corresponding to a voice input. The strategy information may include reference information for determining a single plan when there are multiple plans corresponding to a user input. According to one embodiment, the capsule database (230) may include a follow-up registry that stores information on follow-up actions for suggesting follow-up actions to a user in a specified situation. The follow-up actions may include, for example, follow-up utterances. According to one embodiment, the capsule database (230) may include a layout registry that stores layout information of information output through the electronic device (201). According to one embodiment, the capsule database (230) may include a vocabulary registry that stores vocabulary information included in capsule information. According to one embodiment, the capsule database (230) may include a dialog registry that stores information on a dialogue (or interaction) with a user. The capsule database (230) can update stored objects through a developer tool. The developer tool may include, for example, a function editor for updating action objects or concept objects. The developer tool may include a vocabulary editor for updating vocabulary. The developer tool may include a strategy editor for creating and registering strategies that determine plans. The developer tool may include a dialog editor for creating conversations with users.The developer tool may include a follow-up editor that activates follow-up goals and allows editing of follow-up utterances that provide hints. The follow-up goals may be determined based on currently set goals, user preferences, or environmental conditions. In one embodiment, the capsule database (230) may also be implemented within the electronic device (201).

[0069] The execution engine (240) of one embodiment can produce a result using the generated plan. The end user interface (250) can transmit the produced result to the electronic device (201). Accordingly, the electronic device (201) can receive the result and provide the received result to the user. The management platform (260) of one embodiment can manage information used in the intelligent server (200). The big data platform (270) of one embodiment can collect user data. The analysis platform (280) of one embodiment can manage the quality of service (QoS) of the intelligent server (200). For example, the analysis platform (280) can manage the components and processing speed (or efficiency) of the intelligent server (200).

[0070] In one embodiment, a service server (300) may provide a service (e.g., food ordering or hotel reservation) specified to an electronic device (201). In one embodiment, the service server (300) may be a server operated by a library. Services of the service server (300), such as CP Service A (301) and CP Service B (302), may interact with the front end (210) of the intelligent server (200). The service server (300) in one embodiment may provide information to the intelligent server (200) for generating a plan corresponding to a received user input. The provided information may be stored in a capsule database (230). In addition, the service server (300) may provide result information according to the plan to the intelligent server (200).

[0071] In the integrated intelligence system (20) described above, the electronic device (201) can provide various intelligent services to the user in response to user input. The user input may include, for example, input via a physical button, touch input, or voice input.

[0072] In one embodiment, the electronic device (201) may provide a voice recognition service through an intelligent app (or voice recognition app) stored within the device. In this case, for example, the electronic device (201) may recognize a user utterance or voice input received through the microphone and provide the user with a service corresponding to the recognized voice input.

[0073] In one embodiment, the electronic device (201) may perform a designated action based on the received voice input, either alone or in conjunction with the intelligent server and / or service server. For example, the electronic device (201) may execute an app corresponding to the received voice input and perform a designated action through the executed app.

[0074] In one embodiment, when an electronic device (201) provides a service together with an intelligent server (200) and / or a service server (300), the electronic device (201) can detect a user's speech using the microphone (206) and generate a signal (or voice data) corresponding to the detected user's speech. The electronic device (201) can transmit the voice data to the intelligent server (200) using the communication interface (202).

[0075] An intelligent server (200) according to one embodiment may generate a plan for performing a task corresponding to a voice input received from an electronic device (201), or a result of performing an operation according to the plan, in response to a voice input. The plan may include, for example, a plurality of operations for performing a task corresponding to a user's voice input, and a plurality of concepts related to the plurality of operations. The concept may define parameters input to the execution of the plurality of operations, or result values ​​output by the execution of the plurality of operations. The plan may include association information between the plurality of operations and the plurality of concepts.

[0076] An electronic device (201) of one embodiment can receive the response using a communication interface (202). The electronic device (201) can output a voice signal generated within the electronic device (201) to the outside using the speaker (205), or can output an image generated within the electronic device (201) to the outside using the display module (204).

[0077]

[0078] FIG. 3 is a diagram showing a form in which relationship information between concepts and actions is stored in a database according to various embodiments.

[0079] The capsule database (e.g., the capsule database (230) of FIG. 2) of the intelligent server (e.g., the intelligent server (200) of FIG. 2) may store capsules in the form of a CAN (concept action network) (400). The capsule database may store operations for processing tasks corresponding to a user's voice input and parameters necessary for the operations in the form of a CAN (concept action network).

[0080] The capsule database may store a plurality of capsules (capsule (A) (401), capsule (B) (404)) corresponding to each of a plurality of domains. In one embodiment, one capsule (e.g., capsule (A) (401)) may correspond to one domain (e.g., location (geo)). In addition, one capsule may correspond to at least one service provider (e.g., CP 1 (402) or CP 2 (403)) for performing a function for a domain related to the capsule. In one embodiment, one capsule may include at least one operation (410) and at least one concept (420) for performing a designated function. CAN (400) may store other information such as CP 3 (406). In addition, capsule B (404) may correspond to a service provider (e.g., CP 4 (405)).

[0081] The above natural language platform (e.g., the natural language platform (220) of FIG. 2) can generate a plan for performing a task corresponding to a received voice input using capsules stored in a capsule database. For example, the planner module of the natural language platform (e.g., the planner module (225) of FIG. 2) can generate a plan using capsules stored in a capsule database. For example, a plan (407) can be generated using actions (4011, 4013) and concepts (4012, 4014) of capsule A (401) and actions (4041) and concepts (4042) of capsule B (404).

[0082]

[0083] FIG. 4 is a diagram illustrating a screen for processing voice input received through an intelligent app by an electronic device according to various embodiments.

[0084] The electronic device (201) can execute an intelligent app to process user input through an intelligent server (e.g., the intelligent server (200) of FIG. 2).

[0085] According to one embodiment, on screen 310, when the electronic device (201) recognizes a designated voice input (e.g., wake up!) or receives an input via a hardware key (e.g., a dedicated hardware key), the electronic device (201) may execute an intelligent app for processing the voice input. For example, the electronic device (201) may execute the intelligent app while the schedule app is running. According to one embodiment, the electronic device (201) may display an object (e.g., an icon) (311) corresponding to the intelligent app on the display module (204) (e.g., the display module (160) of FIG. 1, the display module (204) of FIG. 2). According to one embodiment, the electronic device (201) may receive a voice input by a user's speech. For example, the electronic device (201) may receive a voice input such as "Tell me my schedule for this week!" According to one embodiment, the electronic device (201) can display a user interface (UI) (313) (e.g., an input window) of an intelligent app displaying text data of received voice input on a display module (204).

[0086] According to one embodiment, on the 320 screen, the electronic device (201) may display a result corresponding to the received voice input on the display module (204). For example, the electronic device (201) may receive a plan corresponding to the received user input and display 'this week's schedule' on the display module (204) according to the plan.

[0087]

[0088] FIG. 5 is a diagram illustrating an operation of an electronic device processing a user's speech according to one embodiment.

[0089] Referring to FIG. 5, according to one embodiment, the electronic device (501) may include at least a part of the configuration of the electronic device (101) described with reference to FIG. 1 and the electronic device (201) described with reference to FIG. 2. The intelligent server (601) may include at least a part of the configuration of the intelligent server (200) described with reference to FIG. 2. With respect to the electronic device (501) and the intelligent server (601), any description overlapping with that described with reference to FIGS. 1 to 4 will be omitted.

[0090] According to one embodiment, an electronic device (501) (e.g., the electronic device (101) of FIG. 1 or the electronic device (201) of FIG. 2) and an intelligent server (601) (e.g., the intelligent server (200) of FIG. 2) may be connected via a local area network (LAN), a wide area network (WAN), a value added network (VAN), a mobile radio communication network, a satellite communication network, or a combination thereof. The electronic device (501) and the intelligent server (601) may communicate with each other via a wired communication method or a wireless communication method (e.g., wireless LAN (WiFi), Bluetooth, Bluetooth low energy, ZigBee, WiFi direct (WFD), ultra wide band (UWB), infrared data association (IrDA), near field communication (NFC)). The electronic device (501) can communicate with a peripheral device (e.g., the electronic device (102) of FIG. 1 or the electronic device (104) of FIG. 1) located around the electronic device (501).

[0091] According to one embodiment, the electronic device (501) may be implemented as at least one of a smartphone, a tablet personal computer, a mobile phone, a speaker (e.g., an AI speaker), a video phone, an e-book reader, a desktop personal computer, a laptop personal computer, a netbook computer, a workstation, a server, a personal digital assistant (PDA), a portable multimedia player (PMP), an MP3 player, a mobile medical device, a camera, or a wearable device.

[0092] According to one embodiment, the electronic device (501) may obtain a voice signal corresponding to a user's speech and transmit the voice signal to an intelligent server (601). The intelligent server (601) may obtain text data corresponding to the user's speech based on the voice signal. The text data may be converted into computer-readable text by performing automatic speech recognition (ASR) on the voice signal. The intelligent server (601) may analyze the user's speech using the text data. The intelligent server (601) may use the analysis results (e.g., intent information, domain, and / or capsule) to perform a necessary function or provide a response (e.g., question, answer) to be provided to the user to a device (e.g., electronic device (501)). The intelligent server (601) may be implemented in software. Some or all of the intelligent server (601) may be implemented in the electronic device (501). That is, an on-device artificial intelligence (AI) capable of processing speech without communication with an intelligent server (601) can be installed in the electronic device (501). Components such as the natural language platform (220) described with reference to FIGS. 2 to 4 can be implemented in the electronic device (501).

[0093] According to one embodiment, the electronic device (501) can convert a user utterance into text data through an automatic speech recognition module (e.g., an automatic speech recognition module (221) of FIG. 2). The electronic device (501) can determine a domain (and / or intent information) corresponding to the user utterance based on the text data through a natural language understanding model (e.g., a natural language understanding module (223) of FIG. 2).

[0094] According to one embodiment, a domain may correspond to a category (or service) associated with an action (or function) that a user wishes to perform using a device. Domains may be categorized based on the services they provide. For example, a music playback domain may support a music playback service (e.g., a music playback service encompassing the Melon app and the Spotify app). For example, a communication domain may support a communication service (e.g., a communication service encompassing a messaging app, a chat app, and an email app). User utterances may be processed based on each corresponding domain. Tasks corresponding to user utterances may be processed in capsules (e.g., applications). One capsule may correspond to one domain. One capsule may include at least one action and at least one concept for performing a specified function. A capsule may process a task corresponding to a user utterance based on intent information. The intent information may be determined in the capsule or in a natural language understanding module.

[0095] In one embodiment, intent information may be information indicating a user's intent, as determined by interpreting text data. Intent information may include information indicating an action (or function) the user intends to perform using the terminal. Intent information may also be referred to as goal information.

[0096] In one embodiment, a slot may be detailed information related to intent information. A slot may be a parameter required to perform an action based on a user intent. For example, if the text converted from a user's voice input is "What time is it in San Francisco?", the domain may be the "date & time domain," the intent information may correspond to "providing date / time information," the slot may be "San Francisco," and the capsule (e.g., an application) may provide the user with the time in San Francisco. For example, if the text converted from a user's voice input is "What's the weather like here?", the domain may be the "weather domain," the intent information may correspond to "providing weather information," the slot may be "current location," and the capsule may provide the user with the weather at the current location. For example, if the text converted from the user's voice input is "Set the oven temperature to 300 degrees," the domain may be the 'device control domain, the intent information may correspond to 'oven control,' the slot may be '300 degrees,' and the capsule may attempt to set the oven temperature to 300 degrees.

[0097] According to one embodiment, the electronic device (501) can perform a task in response to a user input, as described above. The task may be an operation or function performed in response to the user input. The task may be a unit designated by the manufacturer of the electronic device (501), etc. The electronic device (501) can perform (or support) a task that requires the satisfaction of prerequisites.

[0098] In one embodiment, a prerequisite may be something that must be met in order to perform a task. The conditions that must be met in order to perform a task may vary. The prerequisite may be one defined by the manufacturer of the electronic device (501) among the above conditions. The manufacturer of the electronic device (501) may define as a prerequisite a condition that requires a change in the user's settings and / or a condition that requires an active action from the user. For example, in order to perform a task corresponding to 'receiving a call via text', a condition that must be met may be 'the setting for receiving a call via text must be allowed'. The manufacturer of the electronic device (501) may define as a prerequisite the condition 'the setting for receiving a call via text must be allowed', which requires a change in the user's settings. For example, in order to perform a task corresponding to 'creating a highlight video', the conditions that must be met may be as follows: 1) the gallery app must be running; 2) a photo must exist in the gallery app; and 3) a photo selected for creating a highlight video must exist. The manufacturer of the electronic device (501) may define the conditions 'a photo must exist in the gallery app' and 'a photo selected for highlight video generation must exist' as preconditions, which require active action from the user. The manufacturer of the electronic device (501) may set the condition 'the gallery app must be running' so that the electronic device (501) performs the condition directly as needed. The manufacturer of the electronic device (501) may define sub-steps to satisfy the condition 'the gallery app must be running'. The manufacturer of the electronic device (501) may define sub-steps to satisfy the precondition 'a photo must exist in the gallery app' and the precondition 'a photo selected for highlight video generation must exist'.

[0099] In one embodiment, sub-steps may be sequentially performed to perform a task. The sub-steps may be defined by the manufacturer of the electronic device (501). The sub-steps may include steps for satisfying prerequisites. Additionally, the sub-steps may include steps for satisfying conditions that are not defined as prerequisites but must be satisfied to perform the task (e.g., the gallery app must be running). Depending on whether the prerequisites are satisfied (e.g., whether the required settings are permitted on the electronic device or whether the required data is stored on the electronic device), the user interface (UI) (e.g., a guide) provided by the electronic device to the user may vary.

[0100] In one embodiment, the electronic device (501) can provide guidance to the user throughout the session in which the task is performed. If a new task is completed at least once (e.g., all prerequisites are met) according to the guidance of the electronic device (501), the electronic device (501) can immediately perform the new task when it receives another user request for the new task. The electronic device (501) can enhance the user experience for new tasks.

[0101] Referring to FIG. 5, according to one embodiment, an electronic device (501) may receive an input (e.g., an utterance) (e.g., "Answer a call via text") from a user. The utterance (e.g., "Answer a call via text") may correspond to a task (e.g., a task corresponding to "Answer a call via text") that requires satisfaction of a prerequisite (e.g., that the setting for answering calls via text is allowed). The electronic device (501) may determine whether the prerequisite (e.g., that the setting for answering calls via text is allowed) is satisfied. The prerequisite (e.g., that the setting for answering calls via text is allowed) may not be satisfied. In order to satisfy the prerequisite (e.g., that the setting for answering calls via text is allowed), the electronic device (501) may provide a user interface (UI) (511) (e.g., a setting screen for answering calls via text) to the user based on a deep link. The electronic device (501) can provide guidance to the user throughout a session in which a task (e.g., a task corresponding to 'answer a call by text') is performed.

[0102] According to one embodiment, some or all of the operations performed in the electronic device (501) may be performed in the electronic device (501) and / or the intelligent server (601). The following description will be continued on the assumption that the electronic device (501) performs the operations.

[0103]

[0104] FIG. 6 is a schematic block diagram of an electronic device according to one embodiment, and FIG. 7 is a diagram illustrating new task lists according to one embodiment.

[0105] Referring to FIG. 6, according to one embodiment, the electronic device (501) may include at least a part of the configuration of the electronic device (101) described with reference to FIG. 1 and the electronic device (201) described with reference to FIG. 2. As described above, an on-device artificial intelligence (AI) capable of processing speech without communication with an intelligent server (e.g., the intelligent server (200) of FIG. 2, the intelligent server (601) of FIG. 5) may be installed in the electronic device (501). That is, the natural language platform (220) described with reference to FIGS. 2 to 4 may be implemented in the electronic device (501). With respect to the electronic device (501), any description that overlaps with the description with reference to FIGS. 1 to 4 will be omitted.

[0106] According to one embodiment, the electronic device (501) may include a wireless communication circuit (510) (e.g., the wireless communication module (192) of FIG. 1). The electronic device (501) may include a processor (520) (e.g., the processor (120) of FIG. 1, the processor (203) of FIG. 2). The electronic device (501) may include a memory (530) (e.g., the memory (130) of FIG. 1, the memory (207) of FIG. 2). The processor (520) (e.g., an application processor) may access the memory (530) to execute one or more instructions. The processor (520) may cause the electronic device (501) to provide a response to a user. The memory (530) may store various data used by at least one component (e.g., the processor (520)) of the electronic device (501). The memory (530) may include a new task list database (531).

[0107] According to one embodiment, the processor (520) may be implemented as a circuit (e.g., a processing circuit) such as a system on chip (SoC) or an integrated circuit (IC). The processor (520) may include one or more processors. For example, the processor (520) may include a combination of one or more processors such as a CPU, a GPU, an MPU, an AP, and a CP.

[0108] According to one embodiment, the memory (530) may include one or more memories. The instructions stored in the memory (530) may be stored in a single memory. The instructions stored in the memory (530) may be divided and stored in a plurality of memories. The instructions stored in the memory (530) may be individually or collectively executed by the processor (520) to cause the electronic device (501) to perform and / or control the operations of the electronic device (501) described with reference to FIGS. 5 to 12. The instructions stored in the memory (530) may be individually or collectively executed by a plurality of processors to cause the electronic device (501) to perform and / or control the operations of the electronic device (501) described with reference to FIGS. 5 to 12.

[0109] According to one embodiment, the electronic device (501) can receive a user's input. The electronic device (501) can determine a task corresponding to the user's input based on a first natural language understanding (NLU) model (521) or a second NLU model (522). The first NLU model (521) can correspond to at least a part of the natural language understanding module (223) of FIG. 2. For example, if the task corresponding to the input is a task that does not require satisfaction of a prerequisite, the electronic device (501) can perform the task through the first NLU model (521), and if the task corresponding to the input is a task that requires satisfaction of a prerequisite, the electronic device (501) can perform the task through the second NLU model (522). For example, if the electronic device (501) fails to perform a task determined by the first NLU model (521) (e.g., due to failure to satisfy a prerequisite), the electronic device (501) may continue to perform the task by using the second NLU model (522) (e.g., providing guidance for satisfying the prerequisite and performing sub-steps for satisfying the prerequisite). The second NLU model (522) may be for processing a command for which guidance is provided. In terms of processable tasks, the tasks processed by the first NLU model (521) may be a super set of the tasks processed by the second NLU model (522). The manufacturer of the electronic device (501) may define in advance which task will be performed based on which NLU model. The electronic device (501) can obtain information about a task (e.g., application information (e.g., capsule) associated with the task and / or intent information corresponding to the task) based on the first NLU model (521) or the second NLU model (522).

[0110] According to one embodiment, the electronic device (501) may acquire a list based on application information (e.g., a capsule) associated with a task and / or intent information corresponding to the task. The acquired list may be any one of the lists stored in the new task list database (531). Referring to FIG. 7, lists (700) stored in the new task list database (531) may be confirmed. The list (701) may be associated with a task (e.g., a task corresponding to 'answer a call via text'). A list (701) may include application information (e.g., a capsule) (e.g., a phone application) associated with a task (e.g., a task corresponding to 'answer a text call'), intent information corresponding to the task (e.g., 'answer a text call'), operating system information supporting the task (e.g., operating system X), application version information supporting the task (e.g., phone application version x.xx.xx), prerequisites (e.g., 'answer a text call setting must be allowed'), and sub-steps (e.g., 1. Check whether a call is in progress via a phone app, 2. Check that the Text call setting is on, 3. Execute 'answer a text call'). The capsule, intent information, prerequisites, and sub-steps are described in detail in FIG. 5, so a redundant description will be omitted. A list (702) may be associated with a task (e.g., a task corresponding to 'continue running an app on another device'). A list (703) may be associated with a task (e.g., a task corresponding to 'create a highlight video').

[0111] In one embodiment, the prerequisites may include prerequisites (e.g., 711, 721, 722) related to the configuration of the electronic device (501). The prerequisites (e.g., 711, 721, 722) may be satisfied based on a user interface (UI) provided to the user based on a deep link. The prerequisites may include prerequisites (e.g., 731, 732) related to data stored in the electronic device (501). The prerequisites (e.g., 731, 732) may be satisfied based on the execution of sub-steps. The prerequisites and sub-steps will be described in detail with reference to FIGS. 8 to 10 .

[0112] According to one embodiment, the electronic device (501) may compare information obtained from the second NLU (522) (e.g., application information associated with the task (e.g., capsule), intent information corresponding to the task) with information included in the lists (700) to select a list associated with the task.

[0113] According to one embodiment, the electronic device (501) can check whether it (e.g., the electronic device (501)) supports the task based on the operating system information and application version information included in the list. The electronic device (501) may check whether it supports the task through the operating system check module (523) and the application version check module (524). If the electronic device (501) does not support the task, the electronic device (501) can terminate the session for performing the task. If the electronic device (501) supports the task, the electronic device (501) can maintain the microphone in an activated state throughout the session for performing the task (e.g., to continuously receive the user's input throughout the session for performing the task).

[0114] According to one embodiment, an electronic device (501) supporting a task may collect information of the electronic device (501) to determine whether prerequisites are satisfied. The electronic device (501) may determine whether prerequisites are satisfied based on the information of the electronic device (501). The electronic device (501) may utilize a prerequisite pre-executor (525) and / or a sub-step scheduler (526) to satisfy unsatisfied prerequisites.

[0115] In one embodiment, to satisfy a prerequisite based on a UI provided to a user based on a deep link, the electronic device (501) may utilize a prerequisite pre-executor (525). For example, to satisfy prerequisite (721), the electronic device (501) may execute a deep link to provide a UI (e.g., 511 of FIG. 5) to the user.

[0116] According to one embodiment, for prerequisites to be satisfied by performing a sub-step, the electronic device (501) may utilize a sub-step scheduler (526). The electronic device (501) may determine (e.g., schedule) sub-steps to be performed among the sub-steps based on whether the prerequisites are satisfied. For example, for a prerequisite (731) that is satisfied, the electronic device (501) may decide not to perform sub-step (741). For example, for a prerequisite (732) that is not satisfied, the electronic device (501) may decide to perform sub-step (742). Based on the scheduling result, the electronic device (501) may perform at least some of the sub-steps included in the list. Depending on whether the prerequisites are satisfied, the order in which the electronic device (501) provides the UI may vary.

[0117] According to one embodiment, the electronic device (501) can provide guidance to the user throughout the session in which the task is performed. A single guidance (e.g., a UI) provided by the electronic device (501) may be intended to satisfy a single prerequisite. The electronic device (501) can selectively provide the user with guidance corresponding to the prerequisites. If a new task is completed at least once according to the guidance of the electronic device (501) (e.g., all prerequisites are satisfied), the electronic device (501) can immediately perform the new task when it receives another user request for the new task. The device (501) can enhance the user experience for the new task.

[0118]

[0119] FIGS. 8 to 11 are diagrams illustrating an operation of an electronic device processing a user's speech according to one embodiment.

[0120] Referring to FIG. 8A, an electronic device (801) may receive an input (e.g., an utterance) (e.g., “Answer the call with text”) from a user. The utterance (e.g., “Answer the call with text”) may correspond to a task (e.g., a task corresponding to “Answer the call with text”) that requires satisfaction of a prerequisite (e.g., the setting for answering calls with text is allowed). The electronic device (801) may determine whether the prerequisite (e.g., the setting for answering calls with text is allowed) is satisfied. The prerequisite (e.g., the setting for answering calls with text is allowed) may not be satisfied. The electronic device (801) may not be able to perform the task (e.g., the task corresponding to “Answer the call with text”). As voice assistant functions become more advanced, new tasks that can be performed only when all prerequisites are satisfied are increasing. Even when users attempt to perform new tasks through voice assistants, issues arise where new tasks are not executed because not all prerequisites are met.

[0121] Referring to FIG. 8B , according to one embodiment, the electronic device (501) may receive an input (e.g., an utterance) (e.g., "Answer the call with text") from a user. The utterance (e.g., "Answer the call with text") may correspond to a task (e.g., a task corresponding to "Answer the call with text") that requires the satisfaction of a prerequisite (e.g., that the setting for answering calls with text is allowed). The electronic device (501) can determine whether a prerequisite (e.g., the setting for receiving calls via text is allowed (e.g., 711 of FIG. 7)) is satisfied. The prerequisite (e.g., the setting for receiving calls via text is allowed) may not be satisfied. In order to satisfy the prerequisite (e.g., the setting for receiving calls via text is allowed), the electronic device (501) can provide a user interface (UI) (512) (e.g., a screen for setting text calls) to the user based on a deep link. If the user approves the setting for receiving calls via text, the electronic device (501) can perform a task (e.g., a task corresponding to 'receiving calls via text'). The electronic device (501) can provide a UI (513) (e.g., a screen for receiving calls via text) to the user.

[0122] Referring to FIG. 9A, an electronic device (901) may receive an input (e.g., an utterance) (e.g., “Continue playing on another device”) from a user. The utterance (e.g., “Continue playing on another device”) may correspond to a task (e.g., a task corresponding to “Continue playing on another device”) that requires satisfaction of prerequisites (e.g., Bluetooth on (e.g., 721 of FIG. 7), app continuing on another device (e.g., 722 of FIG. 7)). The electronic device (901), which was performing the task (e.g., the task corresponding to “Continue playing on another device”), may be forced to provide an error message (e.g., “This function is currently unavailable. Please turn on Bluetooth and try again”) to the user due to a failure to satisfy the prerequisite (721). The electronic device (901) may fail to perform the task.

[0123] Referring to FIG. 9B, according to one embodiment, an electronic device (501) may receive an input (e.g., an utterance) (e.g., "Continue running on another device") from a user. The utterance (e.g., "Continue running on another device") may correspond to a task (e.g., a task corresponding to "Continue running the app on another device") that requires satisfaction of prerequisites (e.g., Bluetooth on (e.g., 721 of FIG. 7), app continuing execution on another device (e.g., 722 of FIG. 7)). The electronic device (501), which was performing the task (e.g., the task corresponding to "Continue running the app on another device") through a first natural language understanding (NLU) model (e.g., the first NLU model (521) of FIG. 6), may fail due to unsatisfaction of the prerequisites (721, 722). When the task execution by the first NLU model (521) fails, the electronic device (501) can analyze the user input through the second NLU model (e.g., the second NLU model (522) of FIG. 6). The electronic device (501) can determine whether the user input (e.g., utterance) is a command (e.g., a command for providing guidance) processed through the second NLU model (522). If the user input (e.g., utterance) is a command processed through the second NLU model (522), the electronic device (501) can continue to perform the task (e.g., a task corresponding to 'continue running the app on another device') through the second NLU model (522) (e.g., providing guidance for satisfying a prerequisite and performing sub-steps for satisfying the prerequisite).

[0124] According to one embodiment, the electronic device (501) may provide a UI (514) (e.g., a Bluetooth setting screen) to the user based on a deep link to satisfy the prerequisite (721). The electronic device (501) may provide a UI (515) (e.g., a setting screen for continuing to use an app on another device) to the user based on a deep link to satisfy the prerequisite (722). If the user approves all settings, the electronic device (501) may perform a task (e.g., a task corresponding to “continue running the app on another device”). The electronic device (501) may guide the user to the result of performing the task (e.g., uttering “continue running the app currently running on the device on another device”). Depending on whether the prerequisites are satisfied, the UI provided by the electronic device (501) to the user may vary.

[0125] Referring to FIG. 9c, according to one embodiment, the prerequisite (721) may be satisfied, and the prerequisite (722) may not be satisfied. The electronic device (501) may not provide a UI (e.g., a Bluetooth setting screen) for satisfying the prerequisite (721). In order to satisfy the prerequisite (722), the electronic device (501) may provide a UI (516) (e.g., a setting screen for continuing to use the app on another device) to the user based on a deep link.

[0126] Referring to FIG. 9D , according to one embodiment, the prerequisites (e.g., 721, 722) may be satisfied. The electronic device (501) may perform a task (e.g., a task corresponding to "continue running the app on another device"). The electronic device (501) may guide the user on the result of performing the task (e.g., uttering "continue running the app currently running on the device on another device").

[0127] Referring to FIG. 10A, according to one embodiment, before determining whether a prerequisite is satisfied, the electronic device (501) may first check whether it supports the task based on the operating system information and application version information included in the list. If the electronic device (501) does not support the task, the electronic device (501) may terminate the session for performing the task. The electronic device (501) may inform the user that it does not support the task (e.g., a task corresponding to the utterance "Make a highlight video") (e.g., uttering "This function is not supported by this device").

[0128] Referring to FIG. 10B, according to one embodiment, when the electronic device (501) supports a task, the electronic device (501) may determine whether prerequisites (e.g., whether a photo exists in the gallery app (e.g., 731 of FIG. 7), whether a photo selected for a highlight video exists (e.g., 732 of FIG. 7)) that must be satisfied for the task (e.g., a task corresponding to the utterance “Make a highlight video”) are satisfied. For example, prerequisite (731) may be satisfied, and prerequisite (732) may be not satisfied. Based on whether the prerequisites are satisfied, the electronic device (501) may determine (e.g., schedule) sub-steps to be performed among the sub-steps included in the list (e.g., 703 of FIG. 7). For example, for the prerequisite (731) to be satisfied, the electronic device (501) may decide not to perform the sub-step (741). For example, for an unsatisfied prerequisite (732), the electronic device (501) may decide to perform sub-step (742). The electronic device (501) may perform at least some of the sub-steps included in the list (e.g., 703 of FIG. 7) based on the scheduling result. For example, upon performing sub-step (742), the electronic device (501) may provide the user with a UI (517) (e.g., a photo selection screen) and provide a photo selection guide (e.g., uttering “Please select the photo you want”). If the user selects a photo and all prerequisites (e.g., 731, 732) are satisfied, the electronic device (501) may perform the task. The electronic device (501) may notify the user through the UI (518) that the task performance is complete (e.g., the highlight video generation is complete). The electronic device (501) may provide the user with the task performance result (e.g., the highlight video) through the UI (519). Depending on whether the prerequisites are met, the UI provided to the user by the electronic device (501) may be different.

[0129] Referring to FIG. 11, according to one embodiment, the electronic device (501) can also process (e.g., support) input corresponding to a quick command. A quick command may be an input (e.g., a utterance) designated to perform multiple tasks. A quick command may be designated by a user. A task may correspond to an action or function performed in response to a user input. A task may be a unit designated by the manufacturer of the electronic device (501), etc.

[0130] In one embodiment, three tasks, “Weather notification (first task),” “Stock index notification (second task),” and “Schedule notification (third task),” may be mapped to a quick command called “Briefing.” When the electronic device (501) accurately matches the quick command called “Briefing,” the electronic device (501) may sequentially perform the tasks mapped to the quick command. The electronic device (501) may sequentially perform the aforementioned operations for each task. The electronic device (501) may maintain the microphone in an activated state throughout multiple sessions in which multiple tasks are performed.

[0131]

[0132] FIG. 12 illustrates a flowchart of a method of operating an electronic device according to one embodiment.

[0133] Actions 1210 to 1240 may be performed sequentially, but are not necessarily performed sequentially. For example, the order of each action (1210 to 1240) may be changed, and at least two actions may be performed in parallel.

[0134] According to one embodiment, operations 1210 to 1240 may be understood to be performed in a processor (e.g., processor (520) of FIG. 6) of an electronic device (e.g., electronic device (501) of FIG. 5).

[0135] In operation 1210, an electronic device according to one embodiment (e.g., electronic device (501) of FIG. 5 ) may receive a user's input.

[0136] In operation 1220, an electronic device according to one embodiment may obtain information about a task corresponding to an input.

[0137] In operation 1230, an electronic device according to one embodiment may obtain, based on information, a list including pre-conditions to be satisfied to perform a task and sub-steps to be sequentially performed to perform the task.

[0138] In operation 1240, the electronic device according to one embodiment may selectively perform at least some of the sub-steps based on whether the prerequisites are satisfied.

[0139] According to one embodiment, the operation performed by the electronic device may be performed based on a second NLU model (e.g., the second NLU model (522) of FIG. 6) when the electronic device fails to perform a task determined by a first NLU model (e.g., the first NLU (natural language understanding) model (521) of FIG. 6) (e.g., due to unsatisfied prerequisites).

[0140] In one embodiment, the sub-steps performed by the electronic device may vary depending on whether the prerequisites are met. Depending on whether the prerequisites are met, the user interface (UI) (e.g., a guide) provided by the electronic device may vary. A single guide (e.g., a UI) provided by the electronic device may be designed to satisfy a single prerequisite. The electronic device may selectively provide the user with guides corresponding to the prerequisites.

[0141] According to one embodiment, an electronic device can provide guidance to the user throughout a task-performing session. If a new task is completed at least once (e.g., all prerequisites are met) according to the guidance provided by the electronic device, the electronic device can immediately perform the new task upon receiving a subsequent user request for the new task. This can enhance the user experience for new tasks.
