FIG. 5 is a diagram illustrating an operation in which an electronic device processes a user's speech, according to an embodiment.

Referring to FIG. 5, according to one embodiment, the electronic device 501 may include at least some of the components of the electronic device 101 described with reference to FIG. 1 and the electronic device 201 described with reference to FIG. 2. there is. The intelligent server 601 may include at least some of the components of the intelligent server 200 described with reference to FIG. 2 . With regard to the electronic device 501 and the intelligent server 601, descriptions that overlap with those described with reference to FIGS. 1 to 4 will be omitted.

The electronic device 501 (e.g., the electronic device 101 in FIG. 1 or the electronic device 201 in FIG. 2) and the intelligent server 601 (e.g., the intelligent server 200 in FIG. 2) are connected to a local area network. It may be connected via an 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 use a wired communication method or a wireless communication method (e.g., wireless LAN (Wi-Fi), Bluetooth, Bluetooth low energy, ZigBee, WFD (Wi-Fi), Fi Direct), UWB (ultra wide band), infrared communication (IrDA, infrared data association), and NFC (near field communication) can communicate with each other.

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

According to one embodiment, the electronic device 501 may obtain a voice signal corresponding to the user's utterance and transmit the voice signal to the intelligent server 601. The intelligent server 601 can obtain text data corresponding to the user's utterance based on the voice signal. Text data may be obtained by performing automatic speech recognition (ASR) on a voice signal and converting the voice portion into text that can be read by a computer. The intelligent server 601 can analyze the user's speech using text data. The intelligent server 601 uses the analysis results (e.g., intent information, entities, and/or capsules) to perform necessary functions or provide responses (e.g., questions, answers) to the device (e.g., electronic device 501 )) can be provided. 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 and/or the intelligent server 601 (e.g., the intelligent server 200 in FIG. 2). On-device artificial intelligence (AI), which can process speech without communication with the intelligent server 601, may be installed in the electronic device 501. Components such as the natural language platform 220 described with reference to FIGS. 2 to 4 may be implemented in the electronic device 501.

According to one embodiment, the automatic speech recognition module 221 (eg, the automatic speech recognition module in FIG. 2) included in the natural language platform 220 may convert user utterance into text data. The natural language understanding module 223 included in the natural language platform 220 may determine the domain (and/or intent information) corresponding to the user utterance using text data corresponding to the user utterance. The domain may correspond to a category (or service) related to the operation (or function) that the user wants to perform using the device. Domains may be classified according to services (e.g. apps) related to user utterances. For example, a grace note domain may correspond to a music search service (eg, grace note service). For example, a melon domain may correspond to a music playback service (eg, Melon service). Multiple user utterances may be processed based on each corresponding domain.

According to one embodiment, the electronic device 501 may support a cross-domain scenario. A cross-domain scenario may mean a case where multiple utterances (e.g., multiple consecutive utterances) each correspond to a different domain. When multiple utterances (e.g., consecutive plurality of utterances) are processed in a single domain, subsequent utterances (e.g., consecutive plurality of utterances) containing anaphora (or incompletely containing information for utterance processing) Information (e.g., information corresponding to a substitute word) contained in a previous utterance (e.g., an utterance that occurred before a subsequent utterance) may be used to process an utterance that occurs later in an utterance. According to a comparative example, when each of a plurality of consecutive utterances is processed in a different domain (e.g., a cross-domain scenario), the processing of subsequent utterances containing substitute words (or containing insufficient information for utterance processing) is performed. For this reason, information contained in previous utterances may be difficult to use. According to the comparative example, based on the information security policy, information exchange between different domains may be difficult to achieve in a cross-domain scenario. According to one embodiment, in a cross-domain scenario, the electronic device 501 may use information (eg, cross-domain data) included in a previous utterance. The electronic device 501 can support cross-domain scenarios by using cross-domain data obtained from user utterances.

Referring to FIG. 5 , according to one embodiment, the electronic device 501 may receive an utterance (e.g., “What time is it in San Francisco?”). The electronic device 501 may receive an utterance (e.g., “What time is it in San Francisco?”) followed by a follow-up utterance (e.g., “What’s the weather like here?”). An utterance (e.g., “What time is it in San Francisco?”) may correspond to a date&time domain associated with a service that provides date and time. Subsequent utterances (e.g., “How is the weather here?”) may correspond to the weather domain associated with the weather providing service. Since multiple consecutive utterances each correspond to a different domain, the situation shown in FIG. 5 may be a cross-domain scenario. Subsequent utterances (e.g., “How is the weather here?”) may include substitutes (e.g., here). In a cross-domain scenario, the electronic device 501 is configured to process a subsequent utterance (e.g., "How's the weather here?") that contains a substitute (e.g., here) (or that contains insufficient information for processing the utterance). Information (e.g., cross-domain data) contained in an utterance (e.g., “What time is it in San Francisco?”) can be used (e.g., San Francisco). The electronic device 501 may provide a corresponding response (e.g., "It's sunny in San Francisco") to a subsequent utterance (e.g., "How's the weather here?") based on cross-domain data (e.g., place - San Francisco). there is. The electronic device 501 may support cross-domain scenarios based on cross-domain data obtained from user utterances.

According to one embodiment, some or all of the operations performed on the electronic device 501 may be performed on the electronic device 501 and/or the intelligent server 601. Hereinafter, the explanation will be continued assuming that the electronic device 501 is running.

Referring to FIG. 6, according to one embodiment, the electronic device 501 may include at least some of the components of the electronic device 101 described with reference to FIG. 1 and the electronic device 201 described with reference to FIG. 2. there is. As described above, on-device artificial intelligence (AI), which can process utterances without communication with an intelligent server (e.g., the intelligent server 200 in FIG. 2 and the intelligent server 601 in FIG. 5), is an electronic device. It can be mounted on (501). The natural language platform 220 described with reference to FIGS. 2 to 4 may be implemented in the electronic device 501. With regard to the electronic device 501, descriptions that overlap with those described with reference to FIGS. 1 to 4 will be omitted. The electronic device 501 includes a processor 520 (e.g., processor 120 in FIG. 1, processor 203 in FIG. 2), and a memory 530 (e.g., memory in FIG. 1) electrically connected to the processor 520. 130) and memory 207 of FIG. 2). The processor 520 (eg, an application processor) may access the memory 530 and execute instructions. The processor 520 may perform operations to provide a response to the user. The memory 530 may store various data used by at least one component (eg, the processor 520) of the electronic device 501.

According to one embodiment, the electronic device 501 may support a cross-domain scenario. As described above with reference to FIG. 5, a cross-domain scenario may mean a case where multiple utterances (e.g., multiple utterances in succession) each correspond to different domains. The electronic device 501 uses cross-domain data acquired based on the user utterance and/or the response provided to the user to provide an appropriate response corresponding to a subsequent utterance (e.g., an utterance that occurs after the user utterance) even in a cross-domain scenario. can be provided.

According to one embodiment, the processor 520 may receive the first utterance. The first utterance may correspond to the first domain 521. The processor 520 may provide a first response corresponding to the first utterance based on the first domain 521.

According to one embodiment, the processor 520 may obtain cross-domain data based on the first utterance and/or the first response. The processor 520 may obtain cross-domain data from the first utterance and/or the first response based on the first domain 521. Cross-domain data may be intended to support a cross-domain scenario, which refers to a case where multiple utterances (e.g., multiple utterances in succession) each correspond to different domains. Cross-domain data may include data acquired based on the first utterance and/or the first response (eg, value in FIG. 6) and a category of the acquired data (eg, key in FIG. 6). Categories of acquired data may be predefined. The processor 520 may generate activation information of cross-domain data based on the first domain 521. The processor 520 may transmit cross-domain data and activation information of the cross-domain data to the library domain 523.

According to one embodiment, the processor 520 may store cross-domain data and activation information of the cross-domain data based on the library domain 523. For example, the activation information may be related to how long a speech recognition service (e.g., a speech recognition service activated based on the first utterance) lasts to process a subsequent utterance (e.g., a second utterance) following the first utterance. Session information containing information may be included. For example, activation information may include timeout information corresponding to a category of cross-domain data.

According to one embodiment, the processor 520 may receive a second utterance following the first utterance. The second utterance may correspond to the second domain 522. The second domain 522 and the first domain 521 may be different domains. For example, the first domain may be a grace note domain corresponding to a music search service (eg, grace note service). For example, the second domain may be a Melon domain corresponding to a music playback service (eg, Melon service). The second utterance may be an utterance containing an anaphora. The processor 520 may transmit a category (eg, key in FIG. 6 ) corresponding to a substitute word (eg, a substitute word included in the second utterance) to the library domain 523 .

According to one embodiment, based on the library domain 523, the processor 520 selects a category corresponding to a substitute word (e.g., a substitute word included in the second utterance) and cross-domain data (e.g., based on the first utterance). You can compare the categories of the obtained cross-domain data. Based on the library domain 523, the processor 520 creates categories of substitute words (e.g., substitute words included in the second utterance) and cross-domain data (e.g., cross-domain data obtained based on the first utterance). If a match is made and cross-domain data is activated, cross-domain data can be read.

According to one embodiment, the processor 520 corresponds to the second utterance (e.g., a second utterance including a substitute) based on cross-domain data (e.g., cross-domain data obtained based on the first utterance). A second response may be provided. As described above, the first domain 521 and the second domain 522 corresponding to the first and second utterances may be different domains, and the electronic device 501 may support a cross-domain scenario. Through Table 1, an example of a cross-domain scenario is shown.

[Table 1]

For example, with reference to Table 1, according to one embodiment, the electronic device 501 may receive an utterance (e.g., “What time is it in San Francisco?”). The electronic device 501 may receive an utterance (e.g., “What time is it in San Francisco?”) followed by a follow-up utterance (e.g., “What’s the weather like here?”). An utterance (e.g., “What time is it in San Francisco?”) may correspond to a date&time domain associated with a service that provides date and time. Subsequent utterances (e.g., “How is the weather here?”) may correspond to the weather domain associated with the weather providing service. Since multiple consecutive utterances each correspond to a different domain, the above-described example may be a cross-domain scenario. Subsequent utterances (e.g., “How is the weather here?”) may include substitutes (e.g., here). In a cross-domain scenario, the electronic device 501 is configured to process a subsequent utterance (e.g., "How's the weather here?") that contains a substitute (e.g., here) (or that contains insufficient information for processing the utterance). Information (e.g., cross-domain data) contained in an utterance (e.g., “What time is it in San Francisco?”) can be used (e.g., San Francisco). The electronic device 501 may provide a corresponding response (e.g., "It's sunny in San Francisco") to a subsequent utterance (e.g., "How's the weather here?") based on cross-domain data (e.g., place - San Francisco). there is. The electronic device 501 may support cross-domain scenarios based on cross-domain data obtained from user utterances.

According to one embodiment, when the processor 520 obtains subsequent cross-domain data that has the same category as the cross-domain data, the processor 520 may overwrite the cross-domain data with subsequent cross-domain data. An example of an overwrite operation is shown in Table 2.

[Table 2]

According to one embodiment, referring to Table 2, the processor 520 may obtain and store cross-domain data (e.g., place - San Francisco) based on a user utterance (e.g., “What time is it in San Francisco?”). The processor 520 may obtain subsequent cross-domain data (e.g., place - New York) based on the first subsequent utterance (e.g., "What time is it in San Francisco?") following the user utterance (e.g., "What time is it in San Francisco?"). You can. Since the processor 520 acquired subsequent cross-domain data (e.g., place-New York) with the same category (e.g., place) as the cross-domain data (e.g., place-San Francisco), the cross-domain data (e.g., place-San Francisco) This can be overwritten with subsequent cross-domain data (e.g. place - New York). The processor 520 generates a second follow-up utterance (e.g., "What's the weather here now?") following the first follow-up utterance (e.g., "What is New York?") based on subsequent cross-domain data (e.g., place - New York). can provide a corresponding response (e.g., “It’s raining in New York right now”)

Figure 7 is an example to explain an operation in which an electronic device processes a user's utterance, according to an embodiment.

As described above with reference to FIG. 5, a cross-domain scenario may mean a case where multiple utterances (e.g., multiple utterances in succession) each correspond to different domains. The electronic device 501 can use cross-domain data obtained from a user utterance to provide an appropriate response corresponding to a subsequent utterance (e.g., an utterance that occurs after a user utterance) even in a cross-domain scenario.

According to one embodiment, the processor 520 may receive a first utterance (eg, “What time is it in San Francisco?”). The first utterance may correspond to the date & time domain 721. The processor 520 may provide a first response corresponding to the first utterance based on the date & time domain 721.

According to one embodiment, the processor 520 may obtain cross-domain data (e.g., place - San Francisco) based on the first utterance (e.g., “What time is it in San Francisco?”). The processor 520 may obtain cross-domain data (e.g., place - San Francisco) from the first utterance (e.g., “What time is it in San Francisco?”) based on the date & time domain 721. Cross-domain data refers to a cross-domain scenario (e.g., a case where multiple utterances (e.g., multiple utterances in succession) respectively correspond to different domains (e.g., date & time domain 721, weather domain 722)). It may be to support the situation shown in FIG. 7). Cross-domain data (e.g., place - San Francisco) may include data acquired based on the first utterance (e.g., value=San Francisco in Figure 7) and a category of the acquired data (e.g., key=place in Figure 7). there is.

Cross-domain data and activation information of cross-domain data may be stored in an intelligent server (eg, intelligent server 200 in FIG. 2 and intelligent server 601 in FIG. 6).

According to one embodiment, the processor 520 may receive a second utterance (e.g., “How is the weather here?”) following the first utterance (e.g., “What time is it in San Francisco?”). The second utterance (e.g., “How is the weather here?”) may correspond to the weather domain 722. The weather domain 722 and the date & time domain 721 may be different domains. For example, the date & time domain 721 may correspond to a date and time provision service. The weather domain 722 may correspond to a weather providing service. The situation shown in FIG. 7 may correspond to a cross-domain scenario. Additionally, the second utterance (e.g., “How is the weather here?”) may be an utterance that includes an anaphora (e.g., here). The processor 520 may transmit a category (e.g., key=place in FIG. 7) corresponding to a substitute term (e.g., here) to the library domain 523.

Although not shown in FIG. 7, the speech recognition service activated based on the first utterance (e.g., “What time is it in San Francisco?”) until the second utterance (e.g., “What’s the weather like here?”) is received. It may be continuing. Cross-domain data (e.g., place - San Francisco) obtained based on the first utterance (e.g., “What time is it in San Francisco?”) may be in an active state.

According to one embodiment, the processor 520 determines a second utterance (e.g., "How's the weather here?") that includes a substitute word (e.g., here) based on the cross-domain (e.g., place - San Francisco). A second response may be provided. As described above, the date & time domain 721 and the weather domain 722 respectively corresponding to the first and second utterances may be different domains, and the electronic device 501 may support a cross-domain scenario.

As described above with reference to FIG. 5, a cross-domain scenario may mean a case where multiple utterances (e.g., multiple utterances in succession) each correspond to different domains. The electronic device 501 can use cross-domain data obtained based on the response provided to the user to provide an appropriate response corresponding to a subsequent utterance (e.g., an utterance that occurs after the user utterance) even in a cross-domain scenario.

According to one embodiment, the processor 520 may receive a first utterance (eg, “What is this song?”). The first utterance (e.g., “What is this song?”) may correspond to the grace note domain 821. The grace note domain 821 may correspond to a music search service. Based on the grace note domain 821, the processor 520 may provide a first response (e.g., “It’s IU’s drama”) corresponding to the first utterance (e.g., “What is this song?”).

According to one embodiment, the processor 520 may acquire cross-domain data (e.g., music - artists: [IU], song: [drama]) based on the first response (e.g., "This is IU's drama"). You can. The processor 520 collects cross-domain data (e.g., music - artists: [IU], song: [drama]) from the first response (e.g., "This is IU's drama") based on the grace note domain 821. It can be obtained. Cross-domain data refers to a cross-domain scenario (e.g., diagram) where multiple utterances (e.g., multiple consecutive utterances) respectively correspond to different domains (e.g., grace note domain 821, melon domain 822). It may be to support the situation shown in 8). Cross-domain data (e.g., music - artists: [IU], song: [drama]) is data obtained based on the first response (e.g., "It's IU's drama") (e.g., value = artists: in Figure 8). [IU], song: [drama]) and a category of the acquired data (e.g., key = music in FIG. 8). The processor 520 may generate activation information (eg, 300 ms) of cross-domain data based on the grace note domain 821. Activation information (e.g., 300ms) may be timeout information corresponding to a category (e.g., music) of cross-domain data. The timeout information may be preset, but is not limited to this. The processor 520 may transmit cross-domain data (e.g., music - artists: [IU], song: [drama]) and activation information (e.g., 300 ms) of the cross-domain data to the library domain 523.

According to one embodiment, based on the library domain 523, the processor 520 generates cross-domain data (e.g., music - artists: [IU], song: [drama]) and activation information of cross-domain data (e.g., 300ms) can be saved. Since FIG. 8 assumes on-device operation, cross-domain data and activation information of the cross-domain data are stored in the electronic device 501, but the present invention is not limited to this. Cross-domain data and activation information of cross-domain data may be stored in an intelligent server (eg, intelligent server 200 in FIG. 2 and intelligent server 601 in FIG. 6).

According to one embodiment, the processor 520 may receive a second utterance (e.g., “Put this song on my playlist”) following the first utterance (e.g., “What is this song?”). The second utterance (e.g., “Put this song on my playlist”) may correspond to the Melon domain 822. The melon domain 822 and the grace note domain 821 may be different domains. For example, the grace note domain 821 may correspond to a music search service. For example, Melon domain 822 may correspond to a music playback service. The situation shown in FIG. 8 may correspond to a cross-domain scenario. Additionally, the second utterance (e.g., “Please add this song to my playlist?”) may be an utterance that includes insufficient information for utterance processing (e.g., information about the song to be stored in the playlist). The second utterance (e.g., “Put this song on my playlist”) is slot information (e.g., slot information corresponding to the song to be saved) to perform the action corresponding to the second utterance (e.g., save the song to the playlist). It may be an utterance that does not contain information. The processor 520 may transmit a category (e.g., key=music in FIG. 8) corresponding to slot information (e.g., information about a song) to the library domain 523.

According to one embodiment, based on the library domain 523, the processor 520 configures a category (e.g., music) corresponding to slot information (e.g., information about a song) and cross-domain data (e.g., music - artists: You can compare categories (e.g. music) of [IU], song: [drama]). Based on the library domain 523, the processor 520 generates cross-domain data (e.g., information about a song) when slot information (e.g., information about a song) matches a category (e.g., music) of cross-domain data and the cross-domain data is activated. Example: music - artists: [IU], song: [drama]) can be read. Although not shown in Figure 8, 300 ms after the cross-domain data (e.g., music - artists: [IU], song: [drama]) obtained based on the first response (e.g., "This is IU's drama") was stored. may not have passed. Cross-domain data (e.g. music - artists: [IU], song: [drama]) may be active.

According to one embodiment, the processor 520 provides insufficient information (e.g., information about the song) for speech processing based on cross-domain (e.g., music - artists: [IU], song: [drama]). A second response corresponding to the included second utterance (e.g., “Put this song on my playlist”) may be provided. As described above, the grace note domain 821 and the melon domain 822 respectively corresponding to the first and second utterances may be different domains, and the electronic device 501 may support a cross-domain scenario.
