Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings. In the description of the drawings, the same elements are designated by the same reference numerals, and duplicate description will be omitted.

FIG. 1 is a diagram showing a schematic configuration of an information providing device according to an embodiment of the present disclosure. The information providing device 1 shown in FIG. 1 is a device that provides information to the user U by voice. The information providing device 1 also has a function of responding by voice in response to an utterance from the user U. That is, the information providing device 1 functions as a dialogue device capable of interacting with the user U. The information providing device 1 includes a dialogue module 10, an utterance management module 20, a response information generation module 30, and utterance information generation modules 40A and 40B.

When the user U is watching or is interested in a specific content that progresses in real time, the information providing device 1 shown in the present embodiment provides the information corresponding to the content to the user U. It is characterized by. Specific content that progresses in real time includes, for example, sports, horse racing, stock price fluctuations, and the like. In addition, general information such as weather information and general news, or daily life itself may be treated as "content". When the user U is viewing these contents, the information providing device 1 provides the information to the user U according to the progress of the contents. Hereinafter, the content that the user U is watching or showing interest in may be referred to as "target content". The information providing device 1 provides information on the target content to the user U.

The provision of information to the user U in the above case means not responding to a question from the user U, but voluntarily providing information to the user U from the information providing device 1. The information providing device 1 also has a configuration for responding to a question from the user U. Therefore, the information providing device 1 is a device that responds to a question from the user U and voluntarily provides information to the user U.

The dialogue module 10 of the information providing device 1 is a module that serves as an interface for transmitting and receiving voice information to and from the user U, and has a function of receiving the voice emitted by the user U and a function of emitting voice to the user U. Have. That is, the dialogue module 10 also functions as an output unit that provides voice information to the user U by utterance.

As a function of receiving the voice emitted by the user U, for example, a microphone can be mentioned. Further, as a function of emitting voice to the user U, for example, a speaker can be mentioned. Further, the dialogue module 10 may have a function of performing voice recognition processing of the received user U's voice and converting it into text data. The voice information from the user U converted into text data is sent to the utterance management module 20 described later. Further, the dialogue module 10 may have a function of performing voice synthesis processing of text data provided from the utterance management module 20 described later in order to speak to the user U. When the dialogue module 10 performs the above-mentioned voice recognition processing and speech synthesis processing, transmission / reception of information (information provided to the user U or information acquired from the user U) between the dialogue module 10 and the utterance management module 20. Text data is used for.

The utterance management module 20 manages the voice information to be spoken to the user U. Although the details will be described later, it manages what kind of information about the target content is provided to the user U at what timing according to the progress of the target content. Further, when there is an inquiry from the user U, it also has a function of appropriately responding to the inquiry of the user U. The utterance management module 20 has a function of managing information provision to the user U, including a response to an inquiry from the information providing device 1. The utterance management module 20 accumulates the response sentences generated by the response information generation module 30 and the utterance sentences generated by the utterance information generation modules 40A and 40B, and at an appropriate timing, the user U via the dialogue module 10. Controls the output to. The details of this control will be described later.

The response information generation module 30 is a module that creates a response statement for the content of the inquiry from the user U. The response information generation module 30 generates a response statement for an inquiry from the user U sent from the utterance management module 20. It should be noted that the configuration may be such that when the response statement is generated, communication or the like is performed with an external device or the like to acquire necessary information. The response sentence generated in the response information generation module 30 is sent to the utterance management module 20 and output to the user U.

Each of the utterance information generation modules 40A and 40B has a function of generating an utterance sentence that is spontaneously spoken to the user U. The information providing device 1 shows an example composed of two utterance information generation modules 40A and 40B, but the number of utterance information generation modules may be one or three or more. In the information providing device 1, the utterance information generation module 40A is a module that generates an utterance sentence including information directly linked to the progress of the target content, and the utterance information generation module 40B is a content that is not directly related to the progress of the target content. It is assumed that it is a module that generates an utterance sentence related to information related to. However, when a plurality of utterance information generation modules are provided, the handling may or may not be classified as described above.

The utterance information generation module 40A generates an utterance sentence related to information related to the progress of the target content. The utterance information generation module 40A acquires information from the content progress information providing device 50, which is an external device that provides information related to the progress of the target content, in order to generate the utterance sentence. The content progress information providing device 50 is a device that provides information indicating the progress of the target content in a data format different from the text. The information indicating the progress of the target content includes, for example, information indicating the detailed content of the play when the target content is a sport. In addition, when the target content is stock price fluctuations, information on stocks with large price fluctuations can be mentioned. When these information are acquired from the content progress information providing device 50, the utterance information generation module 40A generates a sentence (natural sentence) for explaining the information.

The utterance information generation module 40B generates an utterance sentence related to information related to the target content. The utterance information generation module 40B acquires information from the content progress information providing device 50, which is an external device that provides information related to the progress of the target content, in order to generate the utterance sentence. Further, information may be acquired from an external DB 60 (database) or the like, which is a device different from the content progress information providing device 50. The information related to the target content includes, for example, information relating to a player who has performed a specific play when the target content is a sport, information explaining a specific play, and the like. When the target content is stock price fluctuations, information on stock prices in the same industry as stocks with large price fluctuations, information on related companies, and the like can be mentioned. The utterance information generation module 40B generates a sentence for explaining the information by combining the information related to the progress of the target content output by the content progress information providing device 50 and the information output by the external DB 60. do.

The response sentences generated by the utterance information generation modules 40A and 40B are sent to the utterance management module 20 and output to the user U.

Next, the utterance management module 20 will be further described with reference to FIG. As shown in FIG. 2, the utterance management module 20 includes an utterance standby information holding unit 21, an utterance determination unit 22, and a score giving unit 23. The score giving unit 23 includes a content score calculation unit 24, an elapsed time score calculation unit 25, and a situation score calculation unit 26.

The utterance standby information holding unit 21 has a function of holding utterance sentences sent from the utterance information generation modules 40A and 40B. That is, it has a function of holding an utterance sentence which is candidate information for providing voice information to the user U by utterance. The utterance determination unit 22 determines whether or not to provide voice information to the user U by utterance, and when uttering, the utterance sentence held by the utterance standby information holding unit 21 is used to the user U. It has a function to select an utterance sentence to be output (spoken) as voice information. The score giving unit 23 assigns a score to each utterance sentence held in the utterance waiting information holding unit 21. The score is a numerical value related to the priority of utterance. It can be said that the higher the score given, the more preferable the information is to be provided to the user U as voice information. In other words, the score is a value set in consideration of the surrounding environment of the user U, and can be said to be a numerical value in consideration of the context.

In the utterance information generation modules 40A and 40B, various utterance sentences are generated according to the progress of the target content. However, if the information providing device 1 outputs all the utterance sentences to the user U, there is a possibility that the voice information output from the information providing device 1 becomes excessive. Further, when there is an inquiry from the user U, it is desirable to give priority to the response to the inquiry. Therefore, it is necessary to appropriately adjust the amount of spoken sentences in the voice information output from the information providing device 1.

Further, it is desired that the content of the voice information output from the information providing device 1 is appropriately changed according to the situation (particularly the progress of the content). For example, in a situation where the target content is tense, the user U may want to know information that explains the progress of the target content itself rather than related information of the target content. On the other hand, in a situation where the change of the target content is small, the information explaining the progress of the target content is reduced, so that it is possible to attract the interest of the user U by providing the related information of the target content.

In view of the above points, the information providing device 1 does not utter all the utterance sentences generated by the utterance information generation modules 40A and 40B, but selects and outputs the utterance sentences in consideration of the progress of the target content and the like. do. The utterance management module 20 manages this.

The utterance standby information holding unit 21 of the utterance management module 20 accumulates utterance sentences (utterance sentences that are candidates for utterance) generated by the utterance information generation modules 40A and 40B. Then, the utterance determination unit 22 determines which of the utterance sentences stored in the utterance information generation modules 40A and 40B is to be output as voice information. The score calculated and given by the score giving unit 23 is used for this determination. The utterance determination unit 22 refers to the score given by the score giving unit 23 for each utterance sentence held in the utterance standby information holding unit 21, and the score is the highest (highest) and a predetermined threshold value. The above utterance sentence is selected as the utterance sentence to be output as voice information.

The score giving unit 23 calculates the score mainly based on three elements, and totals these to calculate the score for each utterance sentence. The three elements are "content score", "elapsed time score", and "situation score", and the scores related to each of these elements are calculated by the content score calculation unit 24, the elapsed time score calculation unit 25, and the situation. It is calculated by the score calculation unit 26.

The "content score" is a numerical value calculated based on the content included in the utterance sentence. The utterance contains multiple words. The content score is a score given based on these plurality of words. The method of assigning the content score is not particularly limited, but as a simple method, a score to be assigned to each word is determined in advance for each word related to the target content, and the corresponding score is added to each word included in the utterance sentence. There is a way to do it. Further, a method of calculating a feature amount for each utterance sentence and using this feature amount as a score may be used by using a method related to machine learning such as deep learning. For example, teacher data is created by preparing multiple pairs of a sentence composed of a set of words and a score (a numerical value shown as a probability of 0 to 1) associated with the importance of this sentence. However, this teacher data may be used to calculate the score of the target utterance sentence by using a deep learning method such as CNN (Convolution Neural Network). The deep learning method or machine learning method used to calculate the score is not particularly limited.

The "elapsed time score" is a numerical value corresponding to the elapsed time since the information providing device 1 output the voice information to the user U last time. The information providing device 1 changes the score according to the length of time from the time when the voice information was output to the user U last time. Regarding the score to be given according to the elapsed time, for example, the elapsed time score calculation unit 25 prepares a score calculation formula based on the elapsed time in advance, and determines a numerical value to be automatically given based on the calculation formula. There is a way to do it. However, the method is not limited to this method.

The "situation score" is a numerical value indicating the necessity of providing information according to the situation of the target content, which is determined based on the progress of the target content. For example, in a situation where the target content is tense, the user U may set a high score because the request for the voice information related to the target content may be high. Further, in a situation where the target content is not tense, the user U may be interested in the related information related to the target content, so that it is possible to set a high score for the related information. As described above, the situation score is a score set according to the progress of the target content.

The status score is set based on the progress of the target content as described above. Therefore, the situation score calculation unit 26 may be configured to calculate the situation score by using the information related to the progress of the content from the content progress information providing device 50 acquired by the utterance information generation modules 40A and 40B. In the case of such a configuration, in the situation score calculation unit 26, as a method of calculating the situation score, it is included in the information related to the progress of the content provided by the content progress information providing device 50, and is included in the progress status of the target content. A method of predetermining a specific score for words with high relevance can be used. For example, when the target content is soccer, a score of 1.0 is given to the "goal" which is considered to be a big event, and a score of 0.1 is given to the "pass" which tends to occur frequently in soccer. A method of giving is conceivable. Further, in the case of soccer, a method of converting the position of the ball during play into a score and using it can be considered. Further, when the target content is a stock price fluctuation, for example, a stock price "fall" or "stop price" can be a word to be scored.

Even when the target content is in a general situation such as daily life in general, a situation score can be given. Specifically, a high score is set in advance for a word indicating an event (for example, information indicating a change in weather) that the user U is expected to provide voice information from the information providing device 1. A low score can be set in advance for a word indicating an event (for example, information indicating an outing schedule of the user U) that the user U is not expected to provide voice information. With such a configuration, even if the target content is not limited to a specific category such as sports, it is possible to give a situation score.

In the situation score calculation unit 26, for example, at the timing of generating the utterance sentence, among the information related to the progress of the content provided by the content progress information providing device 50, from the latest (or a predetermined number of information from the latest) information. A method may be used in which a specific word having a fixed score is taken out, the total of the scores is calculated, and the situation score is obtained. As described above, the method of assigning the situation score is not particularly limited, and various methods can be used. Further, as for the assignment of the situation score, a method such as machine learning may be used in the same manner as the content score.

The situation score may be calculated based on information different from the information acquired by the utterance information generation modules 40A and 40B.

The score calculated in each part may be expressed by a numerical value of 0 or more, or may be expressed by a probability (0 to 1).

As described above, the content score calculation unit 24, the elapsed time score calculation unit 25, and the situation score calculation unit 26 calculate the score for one utterance sentence from different viewpoints. Then, the score giving unit 23 calculates the score for one utterance sentence by adding up the scores calculated in each unit. The method of adding up the scores is not particularly limited, and may be, for example, a simple addition. In addition, when the content score, elapsed time score, and situation score are calculated with probabilities (0 to 1), the total logarithm of each score is calculated to avoid underflow, and one utterance sentence is obtained. It may be a score for.

A score is calculated and given by the score giving unit 23 for each utterance sentence generated by the utterance information generation modules 40A and 40B and held by the utterance waiting information holding unit 21. As a result, as shown in FIG. 3, the utterance standby information holding unit 21 assigns and holds a score for each utterance sentence (queue) waiting for utterance from the information providing device 1. In the example shown in FIG. 3, a score of 0.8 is associated with the utterance sentence "A player shot." In addition, a score of 0.7 is associated with the utterance sentence "A player is from XX." In this way, the utterance standby information holding unit 21 holds the utterance sentences generated by the utterance information generation modules 40A and 40B in a state in which scores are individually assigned.

The score associated with the utterance sentence held by the utterance standby information holding unit 21 may be updated as appropriate. For example, depending on the progress of the target content, the score given to each utterance sentence may not be appropriate. Further, when the utterance using the utterance sentence held by the utterance standby information holding unit 21 or the voice is output from the information providing device 1 in order to respond to the inquiry from the user U, the progress occurs. The time is reset. Therefore, the score held by the utterance waiting information holding unit 21 may be updated by the score giving unit 23 as appropriate (for example, at a predetermined timing).

The utterance determination unit 22 refers to the utterance standby information holding unit 21 periodically (for example, every several hundred meters). Then, the utterance determination unit 22 refers to the utterance sentence having the highest score among the utterance sentences held in the utterance standby information holding unit 21, and the score given to the utterance sentence is a predetermined threshold value. In the above case, it is determined that the user U is to speak based on the utterance sentence, and the utterance sentence is selected. That is, the utterance determination unit 22 has a function as an utterance information selection unit that selects an utterance sentence to be provided as voice information to the user U.

The utterance determination unit 22 does not need to utter when the score given to the utterance sentence having the highest score among the utterance sentences held in the utterance standby information holding unit 21 is smaller than the threshold value. It may be determined that the utterance is not performed until the next opportunity.

The utterance sentence determined to be spoken by the utterance determination unit 22 is deleted from the utterance standby information holding unit 21. As a result, it is possible to prevent the same utterance sentence from being uttered again. Further, the utterance sentence that has passed a predetermined time after being held by the utterance standby information holding unit 21 can also be deleted from the utterance standby information holding unit 21 because the possibility of utterance is low. With such a configuration, among the utterance sentences held in the utterance standby information holding unit 21, utterance sentences that are not planned to be uttered in the future (low probability) are held for a long time, and the amount of data is increased. Can be prevented.

The timing at which the utterance determination unit 22 refers to the utterance standby information holding unit 21 may be appropriately changed depending on the presence or absence of an utterance (inquiry, etc.) from the user U. For example, when there is an utterance from the user U, the information providing device 1 gives priority to responding to the utterance from the user U, and the spontaneous utterance from the information providing device 1 is omitted. Therefore, in such a state, the utterance determination unit 22 may omit the reference itself of the utterance standby information holding unit 21. In the information providing device 1, the utterance management module 20 also manages the response to the utterance from the user U. Therefore, the utterance management module 20 manages the utterance information so that the response to the utterance from the user U and the spontaneous provision of voice information can be compatible with each other based on the utterance priority and the like.

Next, the information providing method in the information providing device 1 will be described with reference to FIG. FIG. 4 describes a procedure related to voluntary provision of a voice information field from the information providing device 1 side. Note that FIG. 4 does not explain the procedure related to the response to the utterance from the user U.

As shown in FIG. 4, the utterance information generation modules 40A and 40B of the information providing device 1 acquire information related to the progress of the target content from the content progress information providing device 50 (S01). The utterance information generation modules 40A and 40B generate utterance sentences for the information providing device 1 to output voice to the user U based on the progress information of the content from the content progress information providing device 50 (S02). The generated utterance sentence is sent from the utterance information generation modules 40A and 40B to the utterance management module 20 (S03).

In the utterance management module 20, the score giving unit 23 first calculates the score of the utterance sentence for the acquired utterance sentence (S04). The score is calculated by the content score calculation unit 24, the content score calculation process, the elapsed time score calculation unit 25, the elapsed time score calculation process, the situation score calculation unit 26, the situation score calculation process, and the score. The granting unit 23 includes a process of adding up these. After calculating the score, the utterance waiting information holding unit 21 holds the utterance sentence and the score corresponding to the utterance sentence (S05). After the utterance sentence is held in the utterance waiting information holding unit 21 (S05), the score may be calculated (S04), and the score may be associated with the utterance sentence and held by the utterance waiting information holding unit 21. ..

In the utterance management module 20, the score giving unit 23 may update the score associated with the utterance sentence held in the utterance standby information holding unit 21 (S06), if necessary.

After that, the utterance determination unit 22 of the utterance management module 20 refers to the utterance standby information holding unit 21 and determines whether to utter the utterance sentence held in the utterance standby information holding unit 21 (S07). When the utterance determination unit 22 determines that the city does not speak, the subsequent processing is not performed, and the utterance determination (S07) is repeated periodically. On the other hand, when it is determined that the utterance is to be performed, the utterance determination unit 22 sends the utterance sentence to be output as voice information to the dialogue module 10 (S08). Then, the utterance sentence is converted into voice by the dialogue module 10, and the output to the user U, that is, the utterance is performed (S09).

As described above, the information providing device 1 according to the present embodiment is an information providing device that provides voice information to the user U by utterance, and is a candidate utterance sentence to be spoken to the user U. , The score giving unit 23 that calculates and gives a score, which is a numerical value related to the priority of the utterance of the utterance sentence, and the utterance sentence and the score given by the score giving unit to the utterance sentence are held in association with each other. The utterance standby information holding unit 21 and the utterance determination unit 22 as the utterance information selection unit that select the utterance sentence held in association with the highest score among the scores held in the utterance waiting information holding unit 21. And the dialogue module 10 as an output unit that outputs the utterance sentence selected by the utterance determination unit 22 as the utterance information selection unit as utterance information.

According to the above-mentioned information providing device 1, a score, which is a numerical value related to the priority of the utterance of the utterance sentence, is calculated and given to each utterance sentence, and is held by the utterance standby information holding unit 21 in association with the utterance sentence. NS. Further, the utterance sentence associated with the highest score is selected by the utterance determination unit 22 as the utterance information selection unit, and is output as voice information by the dialogue module 10 as the output unit. Since the information providing device 1 has such a configuration, the utterance sentence can be selected and output as voice information based on the score related to the priority, so that the user can be notified according to the priority. It becomes possible to make a more appropriate utterance.

Further, in the information providing device 1, the utterance determination unit 22 as the utterance information selection unit displays the utterance sentence associated with the highest score among the scores held in the utterance standby information holding unit 21. When the predetermined condition is satisfied, the utterance sentence is selected. By having such a configuration, it is possible to output the utterance sentence to which not only the score is the highest but also the score satisfying other conditions is given as voice information. Therefore, it is possible to make a more appropriate utterance to the user according to the priority.

In the above embodiment, the predetermined condition is whether or not the score is equal to or higher than the predetermined threshold value. With such a configuration, it is possible to output an utterance sentence whose score is larger than a predetermined threshold value, that is, which is considered to have a sufficiently high priority, as voice information. Therefore, even if the score is the highest among the utterance sentences held in the utterance standby information holding unit, it is possible to prevent the utterance sentence which cannot be said to have a sufficiently high priority from being output as voice information to the user. You can speak more appropriately.

Further, the score giving unit 23 is configured to calculate the score based on the content score corresponding to the content of the utterance sentence.

By calculating the score based on the content score corresponding to the content of the utterance sentence, it is possible to give an appropriate score according to the content of the utterance sentence. Therefore, for example, it is possible to give a score indicating that the utterance sentence relating to the important content has a higher priority, and it is possible to make a more appropriate utterance to the user.

Further, the score giving unit 23 is configured to calculate the score based on the elapsed time score related to the elapsed time from the previous utterance by the own device.

By configuring the score to be calculated based on the elapsed time score related to the elapsed time from the previous utterance by the own device, it is possible to give a score in consideration of the elapsed time. Therefore, for example, it is possible to prevent an utterance when the elapsed time from the previous utterance is too short, so that a more appropriate utterance can be made to the user.

Further, the score giving unit 23 is configured to calculate the score based on the situation score related to the situation of the content for which the voice information is provided.

By configuring the score to be calculated based on the status score related to the status of the content, it is possible to give an appropriate score according to the status of the content. Therefore, for example, when it is better to reduce the provision of voice information due to the situation of the content, it is possible to give a score in consideration of the timing when the provision of voice information is desired, such as lowering the score, and the user can be given a score. You can speak more appropriately.

The information providing device 1 described in the above embodiment is not limited to the above configuration, and various changes can be made.

In the above embodiment, the case where the information providing device 1 is configured by one device has been described, but the functions related to the above information providing device 1 may be distributed and arranged in a plurality of devices. .. For example, each module constituting the information providing device 1 may be an individual device. Further, each module may be composed of a plurality of devices.

Further, in the above embodiment, the case where the information providing device 1 has a function of responding to an utterance (inquiry) from the user U has been described, but the information providing device 1 at least outputs voice information by the utterance. It suffices to have the function related to.

Further, in the above embodiment, the score giving unit 23 has described the configuration for calculating the content score, the elapsed time score, and the situation score, but the score given by the score giving unit 23 includes the content score and the elapsed time score. , And either of the status scores may not be included. Further, the score giving unit 23 may calculate the score based on information or the like different from the above three scores. Further, the score giving unit 23 may calculate the score by combining the above three scores with the score calculated based on other information. As described above, the method of calculating the score given by the score giving unit 23 can be changed as appropriate.

Further, in the above embodiment, the configuration in which the utterance determination unit 22 determines that the utterance is to be spoken as voice information when the score of the utterance sentence is the highest and is equal to or higher than a predetermined threshold value is described. However, the utterance determination unit 22 may be configured to select the utterance sentence having the highest score among the utterance sentences held in the utterance standby information holding unit 21 when other conditions are satisfied. .. Other conditions may be, for example, that the length of the utterance sentence is not more than or equal to a predetermined number of characters. Other conditions (predetermined conditions) may be set in consideration of the function related to the output of voice information from the information providing device 1. Further, the utterance determination unit 22 may be configured to select the utterance sentence having the highest score from the utterance sentences held by the utterance standby information holding unit 21. In this case, the frequency of voice information output may be adjusted by adjusting the selection timing of the utterance sentence (timing of periodic selection of the utterance sentence) by the utterance determination unit 22.
