Note that the information processing device, information processing method, and information processing program according to the present application are not limited to these embodiments. In addition, the same components in the following embodiments will be denoted by the same reference numerals, and duplicated descriptions will be omitted.

(Embodiment)
First, a process executed by an information processing device according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing a process executed by the information processing device according to an embodiment. Fig. 1 illustrates an example of an operation of an information processing system S including an information processing device 1 according to an embodiment.

As shown in FIG. 1, the information processing system S according to the embodiment includes an information processing device 1 and multiple user terminals 100a and 100b. In the following description, the user terminals 100a and 100b will be collectively referred to as user terminals 100 unless otherwise specified.

As shown in FIG. 1, the information processing system S according to the embodiment acquires a voice memo recorded by a user and location information when the voice memo was recorded, and provides the voice memo to other users when the other users satisfy location conditions based on the location information. Note that the voice memo referred to here is voice data indicating the user's voice recorded by the recording function of the user terminal 100. After recording, the voice memo is stored in a memory unit (not shown) of the user terminal 100.

As shown in FIG. 1, in the information processing system S, first, the user terminal 100 accepts a voice memo from the user (step S1). Specifically, the user terminal 100 accepts voice data spoken into a microphone (not shown) provided in the user terminal 100 as a voice memo while a voice recording application is running. The user terminal 100 also acquires location information when the voice memo was recorded and links it to the voice memo.

The location information is, for example, latitude and longitude information, but it may also be the name of a specific location based on latitude and longitude other than latitude and longitude information.

Next, the information processing device 1 acquires the voice memo and the location information linked to the voice memo from the user terminal 100 (step S2). The information processing device 1 collects sets of voice memos and location information from multiple user terminals 100.

Next, the information processing device 1 judges the authenticity of the contents of the voice memo based on the acquired voice memo (step S3). Specifically, the information processing device 1 converts the voice memo into text and performs morphological analysis. Then, the information processing device 1 extracts feature information from the words obtained by the morphological analysis. Furthermore, the information processing device 1 identifies a specific location (such as a store) related to the location information linked to the voice memo, based on the location information, and acquires feature information of the identified location (such as a store menu). Then, the information processing device 1 compares the feature information obtained from the voice memo with the feature information obtained from the location information, and judges the authenticity of the feature information obtained from the voice memo.

The information processing device 1 may also convert the voice memo into a vector using words obtained by morphological analysis of the text of the voice memo. In such a case, the information processing device 1 converts text information of a specific location obtained from the location information (such as reviews of a store) into a vector. Then, the information processing device 1 determines the credibility based on the closeness between the vector of the voice memo and a vector based on the text information of the specific location.

Next, the information processing device 1 links and stores the location information, the voice memo, and the credibility assessment result (step S4).

The information processing device 1 then acquires location information from the user terminal 100b owned by the other user (step S5). Specifically, the information processing device 1 acquires location information of the user terminal 100b in a state in which an application that provides voice memos is running. The location information is, for example, latitude and longitude information, but may also be a name of a specific location based on the latitude and longitude information.

The information processing device 1 then determines whether the location information of the other user satisfies the location condition based on the location information linked to the voice memo (step S6). For example, the information processing device 1 determines that the location condition is satisfied when the location information of the other user is located within a predetermined range of the location information linked to the voice memo. In other words, the information processing device 1 determines that the location condition is satisfied when the other user approaches the location where the voice memo was recorded.

Then, the information processing device 1 provides the voice memo to the other user who is determined to satisfy the location condition via the user terminal 100b (step S7). That is, when the other user approaches the location where the voice memo was recorded, the information processing device 1 plays the voice memo on the other user's user terminal 100b. The information processing device 1 may display the text information of the voice memo by converting the voice memo into text and providing it to the user terminal 100b. The information processing device 1 also provides the other user with a voice memo linked to the above-mentioned credibility determination result.

In this way, according to the information processing device 1 of the embodiment, when another user approaches a location where a voice memo has been recorded, the voice memo can be played back on the user terminal 100b of the other user, allowing the other user to hear, for example, the user's thoughts at that location. In other words, according to the information processing device 1 of the embodiment, voice memos can be used more effectively.

Next, a configuration example of an information processing system S according to an embodiment will be described with reference to FIG. 2. FIG. 2 is a block diagram showing a configuration example of an information processing system S according to an embodiment. As shown in FIG. 2, in the information processing system S according to an embodiment, an information processing device 1 and multiple user terminals 100 are connected to a network N by wire or wirelessly. The network N is, for example, the Internet, a Wide Area Network (WAN), a Local Area Network (LAN), or the like.

The information processing device 1 is a server device that executes the information processing method according to the embodiment. The information processing device 1 acquires a voice memo recorded by a user and location information when the voice memo was recorded, and provides the voice memo to other users when the other users satisfy a location condition based on the location information.

In addition, the information processing device 1 is an information processing device that cooperates with multiple user terminals 100 and provides API (Application Programming Interface) services for various applications (hereinafter, apps) and the like, as well as various data, to the multiple user terminals 100, and is realized by a server device, a cloud system, or the like.

The information processing device 1 may also be an information processing device that provides some kind of web service online to multiple user terminals 100. For example, the information processing device 1 may provide services such as Internet connection, search services, SNS (Social Networking Service), electronic commerce (EC), electronic payment, online games, online banking, online trading, accommodation and ticket reservations, video and music distribution, news, maps, route searches, route guidance, line information, operation information, and weather forecasts as web services. In practice, the information processing device 1 may cooperate with various servers that provide the above-mentioned web services, and may act as an intermediary for the web services or be responsible for processing the web services.

The user terminal 100 is a terminal device owned by a user. The user terminal 100 may be any type of terminal device, such as a smartphone, a desktop PC, a notebook PC, or a tablet PC. The user terminal 100 transmits various types of information to the information processing device 1, etc., and receives information provided by the information processing device 1, etc.

Next, an example configuration of the information processing device 1 will be described with reference to FIG. 3.

Fig. 3 is a diagram showing an example of the configuration of an information processing device 1 according to an embodiment. As shown in Fig. 3, the information processing device 1 has a communication unit 2, a control unit 3, and a storage unit 4. The control unit 3 includes an acquisition unit 31, a determination unit 32, a storage processing unit 33, and a provision unit 34. The storage unit 4 stores user information 41 and voice memo information 42.

The communication unit 2 is realized, for example, by a network interface card (NIC). The communication unit 2 is connected to the network via a wired or wireless connection.

The control unit 3 is a controller, and is realized, for example, by a processor such as a CPU (Central Processing Unit) or MPU (Micro Processing Unit) that executes various programs (corresponding to an example of an information processing program) stored in a storage device inside the information processing device 1 using a RAM or the like as a working area. The control unit 3 is also a controller, and may be realized, for example, by an integrated circuit such as an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or a GPGPU (General Purpose Graphic Processing Unit).

The storage unit 4 is realized, for example, by a semiconductor memory element such as a random access memory (RAM) or a flash memory, or a storage device such as a hard disk or an optical disk.

User information 41 is information about a user. Figure 4 is a diagram showing an example of user information 41. As shown in Figure 4, user information 41 includes items such as "user ID," "attribute information," and "credibility assessment model."

"User ID" is identification information that identifies a user. "Attribute information" is information about the attributes of a user, including, for example, psychographic attributes and demographic attributes. "Credibility determination model" is information about a model that is used when the determination unit 32, described later, determines the credibility of a voice memo. Such a model is generated by a known algorithm in machine learning.

Voice memo information 42 is information related to a voice memo. FIG. 5 is a diagram showing an example of voice memo information 42. As shown in FIG. 5, voice memo information 42 includes items such as "Memo ID", "User ID", "Location information", "Voice memo", and "Judgment result".

"Memo ID" is identification information that identifies the voice memo. "User ID" is identification information that identifies the user who recorded the voice memo, and corresponds to "User ID" in the user information 41 described above. "Location information" is location information when the voice memo was recorded. "Voice memo" is information on the recorded voice memo. "Judgment result" is information indicating the result of the credibility judgment by the judgment unit 32, with "1" indicating credibility and "0" indicating lack of credibility.

Next, we will explain each function of the control unit 3 of the information processing device 1 (acquisition unit 31, determination unit 32, storage processing unit 33, and provision unit 34).

The acquisition unit 31 acquires various information. For example, the acquisition unit 31 acquires a voice memo recorded on the user terminal 100 and location information of the user terminal 100 at the time the voice memo was recorded. The acquisition unit 31 also acquires location information of other users to whom the voice memo is to be provided.

The determination unit 32 determines the authenticity of the content of the acquired voice memo. Specifically, the determination unit 32 converts the voice memo into text and performs morphological analysis. The determination unit 32 then extracts feature information from the words obtained by the morphological analysis. The determination unit 32 also identifies a specific location (such as a store) related to the location information linked to the voice memo based on the location information, and acquires feature information (such as a menu list for the store) of the identified location. The information processing device 1 then compares the feature information obtained from the voice memo with the feature information obtained from the location information to determine the authenticity of the feature information obtained from the voice memo. For example, the determination unit 32 determines that the feature information obtained from the voice memo is authentic when the feature information obtained from the voice memo is similar to the feature information obtained from the location information. For example, the determination unit 32 determines that the feature information obtained from the voice memo is authentic when the menu of the store spoken in the voice memo matches the menu posted on the homepage of the specific store obtained from the location information.

The determination unit 32 may also convert the voice memo into a vector using words obtained by morphological analysis of the text of the voice memo. In such a case, the determination unit 32 converts text information of a specific location obtained from the location information (such as a review of a store) into a vector. Then, the determination unit 32 determines the credibility based on the closeness between the vector of the voice memo and a vector based on the text information of the specific location.

The storage processing unit 33 performs processing to link the voice memo and location information acquired by the acquisition unit 31 with the judgment result of the judgment unit 32 and store them in the storage unit 4 as voice memo information 42.

The providing unit 34 determines whether the other user satisfies a location condition based on the location information linked to the voice memo, and provides the voice memo to the other user if the other user satisfies the location condition. For example, the providing unit 34 determines that the location condition is satisfied if the location information of the other user is located within a predetermined range of the location information linked to the voice memo. In other words, the providing unit 34 determines that the location condition is satisfied if the other user approaches the location where the voice memo was recorded.

Then, the providing unit 34 provides the voice memo to the other user who is determined to satisfy the location condition via the user terminal 100b. In other words, when the other user approaches the location where the voice memo was recorded, the providing unit 34 plays the voice memo on the user terminal 100b of the other user. The providing unit 34 may display the text information of the voice memo by converting the voice memo into text and providing it to the user terminal 100b.

The providing unit 34 may also determine whether to provide a voice memo based on the attribute information of another user who satisfies the location condition. Specifically, the providing unit 34 provides a voice memo when the attribute information of the other user and the content of the voice memo are similar. For example, the providing unit 34 provides the voice memo when the content of the voice memo is soccer-related and the hobbies or affiliations included in the attribute information of the other user are soccer-related. The providing unit 34 may also provide a voice memo when the attribute information of the other user and the attribute information of the user who recorded the voice memo are similar. For example, the providing unit 34 provides the voice memo when the hobbies included in the attribute information of the other user and the user who recorded the voice memo are the same.

The providing unit 34 may also determine whether to provide a voice memo based on the direction in which the other user who satisfies the location condition is facing. The direction in which the other user is facing can be detected, for example, based on the direction of change in the location information of the user terminal 100 held by the other user. For example, the providing unit 34 provides a voice memo when the location information of the other user is within a predetermined range of the location information linked to the voice memo and the other user is facing in the direction of the location information linked to the voice memo.

The providing unit 34 provides the voice memo linked to the credibility determination result by the determining unit 32 to other users. Alternatively, the providing unit 34 may provide only the voice memo determined to be credible to other users, and prohibit the provision of the voice memo determined to be uncredible.

Next, the processing procedure of the process executed by the information processing device 1 according to the embodiment will be described with reference to FIG. 6. FIG. 6 is a flowchart showing the processing procedure of the process executed by the information processing device 1 according to the embodiment.

As shown in FIG. 6, the control unit 3 first acquires the recorded voice memo and location information from the user terminal 100 (step S101).

Next, the control unit 3 determines the authenticity of the voice memo based on the acquired voice memo (step S102).

Next, the control unit 3 links the location information, the voice memo, and the credibility assessment result and stores them in the memory unit 4 as voice memo information 42 (step S103).

The control unit 3 then acquires location information of other users, provides the voice memo to other users who meet the location conditions based on the location information linked to the voice memo (step S104), and ends the process.

The arithmetic unit 1030 controls the output device 1010 and the input device 1020 via the output IF 1060 and the input IF 1070. For example, the arithmetic unit 1030 loads a program from the input device 1020 or the secondary storage device 1050 onto the primary storage device 1040 and executes the loaded program.

For example, when the computer 1000 functions as the information processing device 1, the arithmetic unit 1030 of the computer 1000 realizes the functions of the control unit 3 by executing a program loaded onto the primary storage device 1040.
