It may be all of.

The control unit 31 analyzes the acquired recorded data, converts it into text data (S120), extracts a plurality of keywords from the text data, and generates a word list in the first language (S130). The first language word group to be extracted as a keyword is predetermined. The control unit 31 ranks the extracted plurality of keywords, extracts the top predetermined keywords from the ranked plurality of keywords, and uses the list of the top predetermined keywords as the word list of the first language. It may be generated.

According to one example, the control unit 31 can rank a plurality of extracted keywords based on the frequency of use of each keyword of the user in a predetermined period so that the higher the frequency of use, the higher the rank. The predetermined period may be a recording period corresponding to the acquired recording data, or may be a fixed period in the past with the present as the end point. Examples of fixed periods include one day, one week, and one month.

According to another example, the control unit 31 multiplies the user's frequency of use and the weighting coefficient in a predetermined period for each of the extracted plurality of keywords to obtain the score of each keyword (= frequency of use × weighting coefficient). ) Is calculated, and a plurality of extracted keywords can be ranked so that the higher the score, the higher the rank. The weighting factor can be set to a larger value for words that are useful for second language acquisition. In this case, the data defining the weighting coefficient can be provided from the server device 50 to the user terminal device 30 and stored in the storage unit 32. The weighting factor may be determined based on the user's proficiency in a second language. In this case, the weighting coefficient can be set to a larger value for words that match the proficiency level.

The control unit 31 transmits the word list of the first language generated in S130 in this way to the server device 50 through the wireless communication unit 38 (S140). As shown in FIG. 4, the processing unit 51 of the server device 50 receives the word list in the first language through the communication unit 58 (S210), translates the received word list, and obtains the word list in the second language. Generate (S220). The processing unit 51 transmits the word list of the second language generated in S220 to the user terminal device 30 which is the source of the word list of the first language through the communication unit 58 (S230).

The control unit 31 of the user terminal device 30 receives the word list of the second language corresponding to the word list of the first language transmitted to the server device 50 in S140 from the server device 50 via the wireless communication unit 38 in S150. ..

After that, the control unit 31 outputs a message prompting the user to select a word to be learned from the word list of the second language through the speaker 363 and displays it on the display unit 34. After that, the control unit 31 causes the display unit 34 to display the word selection screen (S160). FIG. 5 shows an example of the word selection screen. According to FIG. 5, the second language is English. In the following, when it is described that the control unit 31 outputs a message, this description means that the control unit 31 outputs a second language message by voice through the speaker 363 and displays the message on the display unit 34.

In S160, the control unit 31 may perform a process for exchanging greetings with the user prior to displaying the word selection screen. For example, as shown in FIG. 6, the control unit 31 can output the message “How are you today?”. In the present specification, the message indicated by the double quotation mark “” corresponds to a message in a second language. In this embodiment, the second language is English. Therefore, in the description of the embodiment, the inside of the double quotation mark “” is shown in English as a second language regardless of the description language of the present specification.

The control unit 31 can display the word selection screen on the display unit 34 after detecting an appropriate response of the user to this greeting. The response from the user is made by voice input through the microphone 361. For example, the control unit 31 outputs a message “Here are the words of the day.” In response to the response “Good.” From the user, and then displays the word selection screen shown in FIG. 5 on the display unit 34. Can be made to.

According to the example shown in FIG. 5, the word group included in the word list of the second language is displayed on the word selection screen with scrolling in the horizontal direction. The user can select one desired word as a learning target from the word group displayed on the word selection screen through the operation unit 35. Then, by pressing the OK button displayed on the word selection screen, the word selection can be confirmed. The control unit 31 can acquire an operation signal related to a word selection operation and a confirmation operation by the user through the operation unit 35 and specify the selected word.

When the word selection confirmation operation is performed, the control unit 31 transmits word selection data indicating the selected word to be learned to the server device 50 through the wireless communication unit 38 (S170). As a result, lesson data corresponding to the selected word is transmitted from the server device 50. The control unit 31 can execute a process for outputting a message praising the word selection by the user during the period from the confirmation operation of the word selection to the reception of the lesson data. According to the example shown in FIG. 6, when the confirmation operation of the word selection is performed, the word selection screen is closed, and the word “selected by the user” is followed by the message regarding the interaction with the user before the display of the word selection screen. "Negotiation" is displayed. Further, a message "Good choice!" Complimenting the selection is output.

When the processing unit 51 of the server device 50 transmits the word list of the second language to the user terminal device 30 in S230 and then receives the word selection data from the user terminal device 30 through the communication unit 58 (S240), the processing unit 51 shifts to S250. .. In S250, the processing unit 51 selects one scenario template to be used this time from a plurality of scenario templates corresponding to the words to be learned indicated by the received word selection data.

As described above, the storage unit 52 stores the scenario template group for each word for each learning item. In S250, the processing unit 51 is a scenario template group corresponding to the learning item (second language usage environment and / or proficiency level) of the corresponding user, and is a scenario template group corresponding to the selected word to be learned. Select one scenario template to be used from the above (S250).

The server device 50 stores user data in the storage unit 52 for each user or user terminal device 30 in association with the corresponding user or user terminal device 30 identification information, specifically, the user ID or device ID. .. User data includes information on the second language usage environment and / or proficiency of the corresponding user.

When registering user data, the processing unit 51 of the server device 50 can acquire information on the usage environment of the second language from the corresponding user by inquiring the corresponding user about the usage environment through the user terminal device 30. it can. The processing unit 51 of the server device 50 periodically inquires the corresponding user of the proficiency level through the user terminal device 30, obtains information on the proficiency level of the second language from the corresponding user, and updates the user data. can do. The processing unit 51 of the server device 50 may be configured to evaluate the proficiency level of the second language from the lesson history of the corresponding user and update the user data.

In S250, the processing unit 51 can specify the learning item of the corresponding user by referring to the user data corresponding to the word selection data transmission source. The processing unit 51 can acquire the identification information of the user or the user terminal device 30 corresponding to the word selection data transmission source from the user terminal device 30 before selecting the scenario template in S250. For example, the processing unit 51 can acquire the identification information of the corresponding user or the user terminal device 30 from the user terminal device 30 together with the word list of the first language in S210 or with the word selection data in S240. ..

After that, the processing unit 51 generates lesson data based on the selected scenario template (S260). The lesson data is data in which the variable part of the scenario template is fixed, and may have the same configuration as the scenario template.

For example, in a lesson based on lesson data, some or all of the example sentences related to the word to be learned provided to the user are not defined as fixed phrases in the scenario template, but are defined as parameters. In other words, the dialogue scenario defined in the scenario template has variable parts where the example sentences change.

The processing unit 51 refers to the corpus database 70 in order to determine an example sentence to be used for this variable portion. The corpus database 70 can be provided by a server device other than the server device 50. Alternatively, the corpus database 70 may be incorporated in the server device 50. For example, the corpus database 70 may be provided in the storage unit 52 of the server device 50. The processing unit 51 generates lesson data by determining an example sentence to be used for the variable part (parameter) of the scenario template based on the corpus database 70.

Specifically, the processing unit 51 selects an example sentence to be used for the variable portion from a plurality of example sentences corresponding to the word to be learned in the corpus database 70. The example sentences to be incorporated into the lesson data can be randomly selected from a plurality of example sentences corresponding to the words to be learned in the corpus database 70, or can be selected according to a predetermined rule. Selecting according to a predetermined rule includes selecting an example sentence corresponding to the usage environment of the second language from a plurality of example sentences. When there are a plurality of example sentences corresponding to the usage environment of the second language, the processing unit 51 can randomly select an example sentence to be used for the variable portion from the plurality of example sentences. By selecting such an example sentence, the user can efficiently learn the example sentence corresponding to the learning item.

Based on the lesson data, a lesson to learn a related word together with the word to be learned may be provided, in which case the scenario template may have a variable part (parameter) about the related word. That is, the processing unit 51 may generate lesson data so as to include related words to be introduced to the user based on the corpus database 70.

After the lesson data is generated in S260, the processing unit 51 executes the lesson data transmission process (S270). In this lesson data transmission process, the processing unit 51 transmits the generated lesson data to the user terminal device 30 of the word selection data transmission source. After that, the processing unit 51 ends the processing shown in FIG.

After transmitting the word selection data to the server device 50, the control unit 31 of the user terminal device 30 receives the lesson data as response data from the server device 50 via the wireless communication unit 38 (S180). After that, the control unit 31 executes the lesson providing process (S190). In the lesson providing process, the control unit 31 interactively provides a lesson based on the received lesson data based on the word to be learned selected by the user by using the speaker 363 and the microphone 361 in a second language. .. At this time, the control unit 31 controls the display unit 34 so that the voice dialogue is displayed on the display unit 34 as character information.

An example of the lesson data providing process executed by the control unit 31 is shown in FIG. Upon receiving the lesson data, the control unit 31 engages in a dialogue regarding the meaning of the word to be learned selected by the user (S310). As shown in FIG. 6, the control unit 31 may display the meaning of the word to be learned in the second language on the display unit 34 following the message output of "Here's the managing of <word>." it can. The message output means the message output by voice and display as described above. As can be understood from FIG. 6, the selected word to be learned is inserted into the <word>.

After displaying the meaning of the word on the display unit 34, the control unit 31 displays the message “Did you”.
get the managing? When the user gives a positive answer to this question by speaking in a second language, for example, "Yes", the control unit 31 receives the input from the microphone 361. Based on this, it is determined that the lesson is advanced to the next stage (Yes in S320). At this time, the control unit 31 can output a message praising the user. After that, the process proceeds to S330. ..

If the user gives a negative answer to the above question, for example, "No", the control unit 31 determines that the lesson cannot be advanced to the next stage (No in S320), and the meaning of the word. The process for continuing the conversation regarding is executed (S310).

For example, the control unit 31 outputs a message "No? OK, the I'll show you one more time. Please look at the screen.", And further, a message "Did you get the screen?". Can be output and the user's response to it can be waited for. Then, when a positive answer is obtained, the process proceeds to S330.

In the above processing, the system response data to be referred to when the user's response is positive and the system response data to be referred to when the user's response is negative are stored in the learning data provided in the scenario template, and each of them is stored. This can be achieved by describing different migration destination IDs in the system response data. In this way, the lesson is performed interactively, and the progress of the lesson is controlled by the control unit 31 according to the content of the user's utterance.

According to the example shown in FIG. 7, the control unit 31 has a dialogue regarding synonyms in S330. The control unit 31 outputs a message introducing similar words corresponding to the word to be learned in the second language, and further outputs a message inquiring whether or not the synonyms could be understood.

When the user gives a positive answer to this question by speaking in a second language, the control unit 31 determines that the lesson is advanced to the next stage (Yes in S340). After that, it shifts to S350. When the user gives a negative answer to the above question, the control unit 31 does not advance the lesson to the next stage (No in S340), and executes a process for continuing the conversation about synonyms (S330). Then, again, a message asking whether or not the synonyms could be understood is output. On the other hand, if a positive answer is obtained, the process proceeds to S350.

In S350, the control unit 31 has a dialogue regarding antonyms. This dialogue can be done in the same way as synonyms. If the user gives a positive answer to the question as to whether or not the antonym can be understood, the control unit 31 determines that the lesson will be advanced to the next stage (Yes in S360), and informs S370. Transition. When the user gives a negative answer to the above question, the control unit 31 does not advance the lesson to the next stage (No in S360) and executes a process for continuing the conversation about the antonym (S350).

In S370, the control unit 31 executes a process for giving an utterance lesson regarding an example sentence. For example, the control unit 31 may display an example sentence through the display unit 34 as "Here's a".
simple sentence. Let's read it out window. Repeat after me. The message "" can be output. Furthermore, the example sentence can be read aloud.

Following the reading of the example sentence, the control unit 31 determines whether or not the user has correctly spoken the example sentence with an appropriate pronunciation based on the input from the microphone 361. Then, if the user utters the example sentence with an appropriate pronunciation without making a mistake, it is determined that the lesson is advanced to the next stage (Yes in S380). Move to S390. In other cases, the process proceeds to S370 and the example sentence is read aloud again. After this reading, the correctness of the utterance of the user's example sentence is similarly evaluated based on the input from the microphone 361.

The control unit 31 repeats such reading of the example sentence and evaluation of the user's utterance up to a predetermined number of times until the user utters the example sentence correctly and with an appropriate pronunciation. Then, when the user utters the example sentence with an appropriate pronunciation without making a mistake, the process proceeds to S390.

When the user utters the example sentence correctly and with an appropriate pronunciation, the control unit 31 can output a message praising the user and a message to end the lesson in S390 to end the lesson. In other cases, the control unit 31 can output a message prompting the lesson again in S390 to end the lesson.

Here, for the sake of simplicity, we have described an example in which a series of lessons ends when the utterance lesson on example sentences is completed. However, the utterance lesson on the example sentence may be given on a plurality of example sentences, or another lesson may be given following the utterance lesson on the example sentence. Output a message asking if you want to continue the lesson, continue the lesson if the user's answer to this message is positive, and give the lesson if the user's answer is negative. The control unit 31 may execute a process based on the lesson data so as to end.

According to the learning support system 1 of the present embodiment described above, the user terminal device 30 acquires the recorded data in which the daily conversation in the user's first language is recorded from the recording device 10 (S110). The user terminal device 30 provides a lesson for learning a second language based on the content of the conversation indicated by the recorded data, and provides a lesson according to the content of the conversation (S190). Therefore, according to this learning support system 1, it is possible to provide the user with a second language lesson based on the user's daily conversation, and it is possible to effectively support the user's learning of the second language. Is.

In particular, the user terminal device 30 provides lessons according to the characteristics of conversation about words.

Therefore, it may be understood that the configuration not explained in the modified example is the same as the corresponding configuration of the learning support system 1 described above.

According to the above embodiment, the server device 50 transmits all the data necessary for a series of lessons to the user terminal device 30 in S270. However, as shown in FIG. 8, the server device 50 may be configured to transmit lesson data step by step to the user terminal device 30 as the lesson progresses.

In the first modification, the processing unit 51 of the server device 50 executes the lesson data transmission process shown in FIG. 8 in S270 (see FIG. 4). Correspondingly, the control unit 31 of the user terminal device 30 can execute the lesson providing process shown in FIG. 9 in S190 (see FIG. 3).

When the process shown in FIG. 8 is started, the processing unit 51 transmits the lesson data generated in S260 to the user terminal device 30 (S410). In S260 of the first modification, the processing unit 51 can generate lesson data for providing the first stage lesson in the series of lessons.

After that, the processing unit 51 receives the response data representing the user response to the utterance of the system generated in the lesson provided to the user from the user terminal device 30 based on the lesson data through the communication unit 58 (S420). The response data may be data representing a response voice from the user to the utterance of the system 1.

The processing unit 51 generates lesson data for providing lessons according to the user's response pattern based on the received response data (S430), and transmits the generated lesson data to the user terminal device 30 through the communication unit 58. (S440). Response data indicating the user's response content generated in the lesson provided to the user from the user terminal device 30 based on the lesson data is received through the communication unit 58 (S450).

Then, if a series of lessons has not been completed (No in S460), the next lesson data is generated and transmitted (S430, S440) based on the response data received in S450, and further response data is received. (S450). That is, the processing unit 51 repeatedly executes S430 to S450 until the end of a series of lessons, whereby the lesson data is used for each lesson stage whose boundary is a branch of the lesson whose content changes according to the user response. Is transmitted to the user terminal device 30. When the series of lessons is completed, the processing unit 51 notifies the user terminal device 30 of the end of the lesson (S470), and ends the data providing process.

When the control unit 31 of the user terminal device 30 starts the lesson providing process shown in FIG. 9, the control unit 31 provides a lesson based on the lesson data received from the server device 50 through the display unit 34 and the speaker 363 (S510), and from the microphone 361. Based on the input, the response data representing the user response to the speech of the system 1 is transmitted to the server device 50 through the wireless communication unit 38 (S520).

The control unit 31 of the user terminal device 30 executes the processes of S510 and S520 each time the lesson data is received from the server device 50 (Yes in S530). When the control unit 31 receives the lesson end notification (Yes in S540) without receiving the lesson data (No in S530), it outputs a message to end the lesson and ends the lesson (S550).

According to the first modification, the lesson data is provided stepwise from the server device 50 to the user terminal device 30, whereby the data necessary for the lesson is selectively provided to the user terminal device 30. According to this modification, the server device 50 can further determine the user's response pattern by voice analysis with high accuracy and high speed. Therefore, according to the modification, the processing load of the user terminal device 30 can be reduced. According to the first modification, the scale of the computer program for learning the second language installed in the user terminal device 30 can be further reduced.

As a second modification, the storage unit 52 may have the attribute data of the corresponding user in the user data for each user or each user terminal device 30. The user attribute data may include data representing the user's gender and / or age (or age group). This attribute data may include data representing the profession of the user and / or information representing the hobby of the user. Examples of hobbies include sports, playing musical instruments, and appreciating art. The user data may include data representing the frequency of taking lessons, as well as the second language usage environment and / or proficiency of the corresponding user.

In this case, in S220, the processing unit 51 extracts a word group corresponding to the user attribute from the word list of the first language received from the user terminal device 30, and translates only the extracted word group into the second language. , May be registered in the word list of the second language.

The storage unit 52 can hold dictionary data that defines a word group to be extracted from the word list of the first language. For example, the dictionary data is configured such that an attribute label is attached to each word for a plurality of words. The attribute label indicates one or more user attributes associated with the corresponding word.

The processing unit 51 selects each of the words registered in the word list of the first language in order, refers to the attribute label attached to the selected word in the dictionary data, and the referenced attribute label indicates one. Alternatively, it is determined whether or not the plurality of user attributes include the user attribute of the user terminal device 30 that has transmitted the word list in the first language. Here, only when it is determined that the word is included, the processing unit 51 can translate the selected word into a second language and register it in the word list of the second language.

Each word in the dictionary data may be labeled with a vocabulary level. In this case, in S220, the processing unit 51 has a vocabulary matching the proficiency level of the user corresponding to the user terminal device 30 that has transmitted the word list of the first language among the word groups registered in the word list of the first language. Level words can be translated into a second language and registered in the second language word list. The proficiency level of the corresponding user can be determined from the user data of the corresponding user.

In order to generate a meaningful second language word list based on user attributes, the target word group extracted by the control unit 31 of the user terminal device 30 as a keyword in S130 can be widely defined. When generating the word list of the first language, the control unit 31 does not have to rank the keywords based on the frequency of use and extract the upper predetermined number of keywords. Extraction of the top predetermined keywords based on the frequency of use may be performed by the server device 50 when generating a word list in a second language.

As a further modification to the second modification, the storage unit 52 does not have to include dictionary data. Alternatively, a function as dictionary data having attribute labels may be incorporated into the corpus database 70. In this case, the processing unit 51 can generate a second language word list by referring to the corpus database 70.

As a further modification to the second modification, the corpus database 70 may include a plurality of example sentences for each word and each user attribute. In this case, in S260, the processing unit 51 has an example sentence corresponding to the user attribute of the user corresponding to the user terminal device 30 of the lesson data transmission destination from among a plurality of example sentences corresponding to the words to be learned in the corpus database 70. One or more of the above can be selected to generate lesson data containing the selected example sentences.

As a further modification to the second modification, the storage unit 52 may include a scenario template group for each word for each combination of the user attribute and the learning item. In this case, in S250, the processing unit 51 refers to the user data of the corresponding user, is a scenario template group corresponding to the combination of the user's learning item and the user attribute, and corresponds to the selected word to be learned. You may select one scenario template to be used from the scenario template group to be used.

S260).

Based on this lesson data, the control unit 31 can provide the user with a second language lesson based on the word to be learned in the conversation environment indicated by the recorded data. For example, if the recorded data indicates a conversation in a business environment, lessons that are useful for the business conversation can be provided to the user. For example, if the recorded data indicates a conversation in a meal environment, the user can be provided with lessons that are useful for the conversation during the meal.

The lesson data may be generated based on not only the conversation of the user during the non-lesson but also the dialogue record between the system and the user at the time of the lesson. Lesson data may be generated so that lessons with different content are provided depending on the user's proficiency level identified from the dialogue record.

In addition, the recording device 10 may be configured to sequentially provide the input voice from the microphone 11 to the user terminal device 30 without storing it as recorded data in the storage unit 17. In this case, the user terminal device 30 can store the input voice from the microphone 11 in its own storage unit 32 as recorded data. The control unit 31 can read the recorded data stored in the storage unit 32 in S110 and execute the processing after S120.

The learning support system 1 may be configured to provide the lesson until the user indicates the intention to end the lesson, and then terminate the provision of the lesson when the intention to end the lesson is indicated.

The user terminal device 30 may be configured to determine user attributes such as the user's gender and age group from the recorded data in S120. The user terminal device 30 may transmit the determined user attribute information to the server device 50 together with the word list in the first language.

The user terminal device 30 may be configured to determine important words based on the user's utterance tone identified from the recorded data and register the important words in the word list of the first language. Important words may be determined based on the general frequency of use of words identified from the equilibrium corpus and the frequency of individual word use of the user.

The corpus database may be prepared for each user attribute. The processing unit 51 of the server device 50 refers to the corpus database associated with the user attribute corresponding to the user terminal device 30 that has transmitted the word list in the first language, and matches the user attribute from the word list in the first language. The word group to be used may be translated into a second language to generate a word list in the second language. The processing unit 51 may generate lesson data by referring to the example sentences of the corpus database.

The user terminal device 30 may extract a group of keywords related to the user attribute of the corresponding user from the recorded data based on the user attribute to generate a word list in the first language.
The user terminal device 30 may be configured to generate a word list in the first language based on the keywords included in the recorded data in the time zone specified by the user among the recorded data. Only the recorded data in the time zone specified by the user may be provided to the user terminal device 30, the server device 50, or the voice recognition server 80.
