FIG. 1 is a diagram for explaining an outline of an audio system according to an embodiment of the present invention. As shown in FIG. 1, a user 101 has a terminal device 102. The terminal device 102 has a device that acquires sound such as a microphone. The terminal device 102 may further include an image capturing device such as a camera. The user 101 speaks at the position A toward the terminal device 102. At this time, the terminal device 102 acquires audio information B around the terminal device 102 using a microphone or the like. If the terminal device 102 has an image capturing device, image information may be acquired together with acquisition of audio information. Hereinafter, information including audio information acquired by the terminal apparatus 102 is referred to as content.

  In addition, the terminal device 102 acquires position information A representing the current position. For example, a radio wave received from a GPS (Global Positioning System), a mobile phone base station, a wireless LAN (Local Area Network) access point, or the like is used. Alternatively, the position information may be acquired by optically reading a barcode or the like that is arranged at or near position A and coded with location information. The terminal apparatus 102 that has acquired the position information A and the audio information B transmits information 103 including the position information and content including the audio information to the server 104.

  When the server 104 receives the information 103 from the terminal device 102, the server 104 extracts the position information and the voice information from the received information 103, and stores the position information in the voice information in the database 105 accessible by the server 104. Record in association. Note that “extraction” may include not only acquisition of information but also conversion of acquired information. For example, conversion of an audio information encoding method is included. Here, for example, if “A” and “12345.wav” are extracted from the received information 103, “A” and “12345.wav” are recorded in the same row of the database 105. Here, “12345.wav” is a file name in which the audio information B is recorded. Further, if the content includes video information, the video information can also be extracted, and the positional information can be associated and recorded in the database 105.

  Also, the conversion of the audio information may include changing the frequency of the audio frequency component or changing the intensity of the frequency component. By such conversion, a male voice can be processed into a female voice, an adult voice can be processed into a child voice, or a celebrity voice can be processed. The processing method may be determined according to the position information, determined according to the date and time when the voice information is acquired, or the user 101 may specify the terminal device 102. By such processing, various effects can be added to the sound reproduction described later. It also eliminates the discomfort of users who feel uncomfortable with listening to and listening to their own voice.

  As shown in FIG. 1, the database can store a field indicating the date and time when the information 103 was received and a field indicating the user name of the user 101 of the terminal device 102 that transmitted the information 103. It may be. Information recorded in the field indicating the date and time may be transmitted from the terminal device 102 together with the information 103. In addition, for example, a program for executing an embodiment of the present invention is operating in the terminal device 102, and the user name is activated, starts communication with the server 104, and transmits information 103. This is user identification information acquired when the user logs in to the server 104 or the like until then. Alternatively, the user name may be a name arbitrarily set when the user 101 transmits the information 103.

  By storing the field indicating the date and time in the database, it becomes possible to acquire the audio information in the same season, the same time zone, etc. in addition to the same location where the audio information was acquired, and the impression is doubled. In addition, since a field indicating a user name is stored in the database, a user who desires to acquire voice information of a specific user appears, and the voice system according to the present embodiment is used for promotional activities of the user. Can be useful.

  It is assumed that after the server 104 records the position information A in association with the audio information B, another user 106 possesses the terminal device 107 and moves. The terminal device 107 acquires the current position information using the above-described GPS or the like, and transmits the current position information to the server 104 regularly or irregularly. The server 104 searches the database 105 using the received position information, and searches for voice information recorded in association with the position information transmitted from the terminal device 107.

  Therefore, when the user 106 is positioned at the position A, the terminal device 107 transmits the position information 108 representing the position A to the server 104. At this time, when the server 104 searches the database 105, voice information associated with the position A is acquired. Thereafter, the server 104 transmits the acquired audio information as audio information 109 to the terminal device 107. The terminal device 107 that has received the audio information 109 reproduces the audio information 109 and outputs the audio represented by the audio information B. Note that the user 106 may be the same person as the user 101 or a different person. Further, the terminal device 102 and the terminal device 107 may be the same or different. If video information or the like is recorded in the database 105 in association with the position information, the video information or the like is also transmitted to the terminal 107 and displayed on the display.

  Note that the processing described above for the voice information may be performed when the server 104 transmits to the terminal device 107.

  According to the embodiment of the present invention as described above, the voice information acquired by the user 101 in the terminal device 102 can be reproduced by the terminal device 107 of the user 106 in the position A. Thereby, for example, the user 106 can relive the emotions expressed by the user 101 and the like, and the emotions can be shared among a plurality of users.
