<Sound release device 20>
The sound emitting device 20 is installed in a specific facility P. Specifically, the sound emitting device 20 is an output device that emits a voice (hereinafter referred to as “guidance voice”) V for guiding various information to the user of the facility P. For example, transportation facilities such as stations or bus stops, transportation facilities such as railroads or buses, commercial facilities such as shops or restaurants, accommodation facilities such as inns or hotels, exhibition facilities such as museums or art galleries, sightseeing such as historical sites or famous places. Facilities, sports facilities such as stadiums or gymnasiums, etc. are exemplified as facility P. For example, the business hours of the facility P, the products sold in the facility, or the guidance voice V for informing the occurrence of an emergency (for example, a fire) in the facility P is emitted. Alternatively, in-vehicle broadcasting that notifies the operation status such as train delay, arrival of the train, precautions when getting on and off, etc. in the train or bus vehicle (facility P) is exemplified as the guidance voice V. In reality, a sound emitting device 20 is installed in each of a plurality of facilities, and a guidance voice V (an example of voice) is emitted in the facility. However, in the following explanation, one facility P is focused on for convenience. do. The guidance voice V emitted by the sound emitting device 20 may be a voice pronounced by an employee of the facility P, or may be a voice prepared by voice synthesis or recording, for example. For example, in parallel with the instruction of the character string by the employee, the guidance voice V represented by the character string may be generated in real time by voice synthesis.

In addition to the guidance voice V, the sound emitting device 20 of the first embodiment emits a sound representing the voice information D1 and a sound representing the position information D2. The voice information D1 is information indicating the content of the guidance voice V (for example, a character string representing the pronunciation content of the guidance voice V). In the first embodiment, the identifier that identifies the content of the guidance voice V is used as the voice information D1. Different voice information D1 is set in advance for each guidance voice V. The voice information D1 is information for specifying the related information R corresponding to the guidance voice V.

The position information D2 is information indicating a position where sound is emitted by the sound emitting device 20 (hereinafter referred to as “sound emitting position”). Different position information D2 is set in advance for each sound emission position. For example, the name of the facility P where the sound emitting device 20 is installed, the area where the facility P is located (for example, the division between the Kanto region and the Kinki region), or the geographical point such as the latitude and longitude of the facility P. , Illustrated as a sound emitting position. The sound emitting position is not limited to the information indicating a geographically specific point, and may be, for example, the number of floors in the facility P or a specific place in the facility P. Further, the position information D2 may be information for identifying each sound emitting device 20. In the first embodiment, the identifier that identifies the sound emission position is used as the position information D2.

By supplying the acoustic signal X to the sound emitting device 20, the sound including the guidance voice V and the voice information D1 and the sound representing the position information D2 are emitted from the sound emitting device 20. The acoustic signal X is a signal representing a sound including the guidance voice V, the sound representing the voice information D1, and the sound representing the position information D2. The sound emitting device 20 of the first embodiment functions as an acoustic device for reproducing the guidance voice V, and also transmits voice information D1 and position information D2 to the surroundings by acoustic communication using sound waves as air vibration as a transmission medium.

To. The voice information D1 is transmitted every time the guidance voice V is emitted. For example, the voice information D1 is transmitted together with the sound of the guidance voice V (for example, in parallel with or before and after the sound of the guidance voice V). On the other hand, the position information D2 is repeatedly transmitted at a predetermined cycle separately from the sound emission of the guidance voice V. The position information D2 may be transmitted together with the sound of the guidance voice V. However, the transmission of the voice information D1 and the transmission of the position information D2 do not overlap in time.

The acoustic signal X is generated by adding an audio signal representing the guidance voice V, a modulated signal representing the audio information D1 as an acoustic component, and a modulated signal representing the position information D2 as an acoustic component. Each modulation signal is generated, for example, by frequency-modulating a carrier wave having a predetermined frequency with each information (voice information D1 or position information D2). A modulated signal may be generated by sequentially executing diffusion modulation of each information using a diffusion code and frequency conversion using a carrier wave having a predetermined frequency. The frequency band of the modulated signal is a frequency band in which the sound can be emitted by the sound emitting device 20 and the sound can be picked up by the terminal device 10A, and the frequency band of the sound heard by the user of the terminal device 10A in a normal environment. It is set to a higher frequency band (for example, 18 kHz or more and 20 kHz or less). Therefore, the user can hardly hear the acoustic components of the voice information D1 and the position information D2. However, the frequency band of the modulated signal is arbitrary, and it is possible to generate a modulated signal within the audible band, for example.

Similar to the first embodiment, the related information acquisition unit 53 of the third embodiment acquires the related information R from the voice information D1 transmitted from the terminal device 10A and transmits the related information R to the terminal device 10A. The provision information generation unit 54 of the third embodiment generates the provision information Q by using the voice table Tb.

Hereinafter, the provided information Q generated by the distribution device 30 of the third embodiment will be described. In the third embodiment, a case where the provided information Q indicating the language used by the user located near the specific sound emission position is generated is illustrated. When there are many users who use a specific language (that is, the terminal device 10A in which a specific language is set) near the sound emission position, the language to which the position information D2 indicating the sound emission position is commonly associated. Information D4 is centrally registered in the voice table Tb in a short time. Therefore, for each language, by calculating the number of registered records N including the position information D2 and the language information D4 indicating a specific sound emission position, it is possible to estimate the language in which a large number of people are used at the sound emission position. can.

For example, the provided information generation unit 54 identifies a record including the position information D2 indicating a specific sound emission position from the voice table Tb. Next, the provided information generation unit 54 generates the provided information Q by classifying the specified plurality of records into each language using the language indicated by the language information D4 of the record. For example, the number of people who use each language at the sound emission position indicated by the position information D2 of the record is estimated according to the registered number N of the classified records, and the provided information Q indicating the language with the largest estimated number of people is generated. Will be done. That is, the provided information Q indicating the language most presumed to be used at a specific sound emission position is generated. The language information D4 is information used to generate the provided information Q. It should be noted that the provided information Q indicating a plurality of languages in which the number of classified records is ranked higher in descending order may be generated.

In the third embodiment, a display terminal for guidance such as an electric bulletin board installed in a transportation facility or an electronic signage (digital signage) installed in a commercial facility is exemplified as a terminal device 10B. The distribution device 30 has a sound emission position indicated by the position information D2 corresponding to the language information D4 used for generating the provision information Q (that is, the provision information Q indicates) among the plurality of terminal devices 10B registered in the terminal table Tc. The provided information Q is transmitted to the terminal device 10B located near the sound emitting position where many users who use the language are located). The terminal device 10B displays various information in the language indicated by the provided information Q transmitted from the distribution device 30, for example. That is, the information is displayed in a language that is used by a large number of people in the vicinity of the sound emitting position.

In the third embodiment, the terminal device 10A generates the language information D4, but the sound emitting device 20 may transmit the language information D4 to the terminal device 10A together with the voice information D1 and the position information D2. For example, information indicating the language of the guidance voice V is transmitted to the terminal device 10A as language information D4. The terminal device 10A transmits the language information D4 transmitted from the sound emitting device 20 to the distribution device 30. Further, with the above configuration, it is possible to collect information as to which language of the guidance voice V is being emitted from the sound emitting device 20.

<Modification example>
Specific modifications added to each of the above-exemplified embodiments are illustrated below. A plurality of embodiments arbitrarily selected from the following examples may be appropriately merged to the extent that they do not contradict each other.

(1) In each of the above-described embodiments, the provided information Q is generated by using the plurality of voice information D1 stored in the storage device 32 (voice table Tb), but the plurality of voice information D1 stored in the storage device 32. Is used for various purposes other than the generation of the provided information Q. For example, a plurality of voice information D1 stored in the storage device 32 or the contents thereof may be statistically analyzed and utilized for various businesses (for example, marketing). Information other than the voice information D1 stored in the storage device 32 (for example, position information D2, time information D3, language information D4) may be used for analysis. Further, the voice table Tb may be provided as a searchable database. As understood from the above description, the generation of the provided information Q is omitted.

(2) In each of the above-described embodiments, the sound emitting device 20 emits the guidance voice V, but the sound emitted by the sound emitting device 20 is not limited to the guidance voice V. That is, the voice picked up by the terminal device 10A may be a voice other than the guidance voice V. For example, the terminal device 10A may pick up a voice such as a musical sound (playing sound of a musical piece) or an alarm sound, and generate voice information D1 indicating the voice. The guidance voice V is an example of voice.

(3) In each of the above-described embodiments, the identifier for identifying the guidance voice V is exemplified as the voice information D1, but the voice information D1 is not limited to the above examples. For example, the character string representing the utterance content of the guidance voice V may be the voice information D1. The information extraction unit 41 of the terminal device 10A identifies the character string representing the utterance content of the guidance voice V as the voice information D1 by voice recognition for the acoustic signal Y generated by the sound collecting device 14. For speech recognition for the acoustic signal Y, known techniques such as recognition processing using an acoustic model such as HMM (Hidden Markov Model) and a language model showing linguistic restrictions can be arbitrarily adopted. In the configuration in which the terminal device 10A generates the voice information D1 by voice recognition, the transmission of the voice information D1 by the sound emitting device 20 is omitted. The terminal device 10A receives the related information R corresponding to the character string (voice information D1) representing the utterance content of the guidance voice V from the distribution device 30. Further, the voice information D1 may be information (for example, a URL) indicating the location of the information. As understood from the above examples, the voice information D1 is comprehensively expressed as information indicating the voice picked up by the terminal device 10A. Similarly, the position information D2 is not limited to the identifier that identifies the sound emission position. For example, the sound emitting device 20 transmits the character string indicating the sound emitting position (for example, the name of the facility) or the information indicating the location of the content indicating the sound emitting position (for example, URL) as the position information D2 to the terminal device 10A. May be good.

(4) The position information D2 and the time information D3 exemplified in each of the above-described embodiments are comprehensively expressed as situation information indicating the state of sound collection by the terminal device 10A. That is, the position where the guidance voice V is picked up and the time when the guidance voice V is picked up are exemplified as the sound picking up situation. The situation information is not limited to the position information D2 and the time information D3. For example, an image captured by the terminal device 10A, a position acquired by using a positioning satellite (for example, a GPS satellite), a moving speed, an application usage status, a browsing history by a web browser, information notified by push, etc. The status information is arbitrary as long as it is information generated or acquired by the terminal device 10A when the guidance voice V is picked up.

(5) In the first embodiment and the second embodiment, the terminal device 10A transmits the voice information D1 and the status information to the distribution device 30, and in the third embodiment, the terminal device 10A receives the voice information D1 and the status information. Although the language information D4 is transmitted to the distribution device 30, it may be omitted that the terminal device 10A transmits information other than the voice information D1.

Further, the information transmitted by the terminal device 10A in addition to the voice information D1 is not limited to the status information and the language information D4. For example, the terminal device 10A that picks up the guidance voice V notifying the occurrence of an emergency (for example, a fire) can pick up sounds other than the guidance voice V (for example, a siren) together with the guidance voice V. In the above situation, information indicating the classification of the sound picked up by the terminal device 10A together with the guidance voice V (hereinafter referred to as “classification information”) may be added to the voice information D1 and transmitted to the distribution device 30. For example, classification information indicating a siren indicating an emergency situation, or classification information indicating an abnormal sound such as an explosion sound and an impact sound is exemplified. Known techniques can be arbitrarily adopted for the generation of classification information. For example, classification information is generated by analysis of the acoustic signal Y. The terminal device 10A transmits the voice information D1 and the classification information to the distribution device 30, and the distribution device 30 (storage control unit 52) stores the received voice information D1 and the classification information in the storage device 32 in association with each other. .. The terminal device 10A adds an acoustic signal Y including sounds other than the guidance voice V to the voice information D1 and transmits the sound signal Y to the distribution device 30, and the distribution device 30 generates classification information by analyzing the acoustic signal Y. May be good. Further, information (for example, identification information) regarding the sound emitting device 20 which is the sound emitting source of the guidance voice V collected by the terminal device 10A may be added to the voice information D1 and transmitted from the terminal device 10A.

(6) In the first embodiment and the second embodiment, a plurality of voice information D1s are used to generate the provided information Q, but the provided information Q may be generated without using the plurality of voice information D1s. For example, the provided information Q may be generated using only the status information. For example, the provision information Q indicating the degree of congestion may be generated for each sound emission position according to the number of position information D2 indicating each sound emission position registered in the voice table Tb.

(7) Since the voice information D1 can be received only at a specific sound discharge position where the guidance voice V can be picked up, the voice information D1 can also be expressed as information indicating the sound discharge position. Therefore, it is not essential to use the position information D2 transmitted from the plurality of terminal devices 10A in the generation of the provided information Q exemplified in each of the above-described embodiments. That is, the transmission of the position information D2 by the sound emitting device 20 may be omitted.

Further, the terminal device 10A acquires accurate position information D2 of the terminal device 10A by receiving radio waves from a positioning satellite (for example, a GPS satellite), and adds the position information D2 to the voice information D1 for transmission. You may. Both the position information D2 specified from the satellite radio wave and the position information D2 received by acoustic communication from the sound emitting device 20 may be registered in the voice table Tb. The position information D2 specified from the satellite radio wave indicates the absolute position of the terminal device 10A, whereas the position information D2 received by acoustic communication indicates the sound emission position, which is a semantic difference. For example, assuming that the terminal device 10A is located inside a moving body such as a train, the absolute position indicated by the position information D2 specified from the satellite radio wave changes in conjunction with the movement of the moving body, but in acoustic communication. The sound emission position indicated by the received position information D2 does not change.

Further, the high-precision position information D2 (hereinafter referred to as “high-precision position information”) generated by the telecommunications carrier that manages the communication network 70 to which the terminal device 10A is connected may be used to generate the provided information Q. For example, high-precision position information corresponding to the position where the terminal device 10A is located at the time indicated by the time information D3 added to the voice information D1 is registered in the voice table Tb in association with the voice information D1. With the above configuration, the high-precision position information generated by the telecommunications carrier can be used to utilize the plurality of voice information D1s. As understood from the above description, in each of the above-described embodiments, the transmission of the position information D2 to the distribution device 30 is omitted. The provided information Q may be generated according to the correspondence between the high-precision position information and the voice table Tb. For example, the provided information Q may be generated from the voice table Tb in consideration of the movement tendency of a large number of terminal devices 10A indicated by the high-precision position information.

(8) In each of the above-described embodiments, the provided information Q is generated by using the plurality of voice information D1, but it is not essential to use the plurality of voice information D1 in the generation of the provided information Q. That is, the provided information Q may be generated by using one voice information D1. For example, when the voice information D1 of the guidance voice V notifying the emergency situation is transmitted from the terminal device 10A to the distribution device 30, the voice information D1 may be used to generate the provision information Q notifying the emergency situation. In the above configuration, the distribution device 30 functions as an element for transmitting the provided information Q generated by using the voice information D1 to the terminal device 10B. The difference between the terminal device 10A and the terminal device 10B does not matter.

(9) In each of the above-described embodiments, the distribution device 30 transmits the related information R to the terminal device 10A, but the transmission of the related information R to the terminal device 10A may be omitted. That is, the terminal device 10A is used as an information terminal for collecting the voice information D1 and transmitting it to the distribution device 30.

(10) In each of the above-described embodiments, the provided information Q is transmitted to the terminal device 10B registered in the terminal table Tc, but the provided information Q may be transmitted to the terminal device 10A. Further, the information provision Q may be provided to the business operator of the facility P in which the sound emitting device 20 is installed. For example, the provision information generation unit 54 generates the provision information Q that informs the increasing tendency of the voice information D1 indicating a specific guidance voice V (for example, the guidance voice V emitted at the facility P). For example, when the voice information D1 corresponding to the position information D2 indicating the facility P tends to increase in a short time among a plurality of voice information D1 registered in the voice table Tb (for example, when the number of registrations exceeds a predetermined threshold value). ), The provided information Q is generated. For example, the provision information Q notifying that the number of registrations of the voice information D1 indicating the specific guidance voice V has increased, or the provision information Q notifying the registration number of the voice information D1 is generated. The generated provided information Q is transmitted to the information terminal of the user of the facility P. The user's information terminal is, for example, a control device for controlling the sound emitting device 20. The information terminal estimates the congestion status (for example, the degree of congestion) of the facility P from the increasing tendency of the voice information D1 indicated by the provided information Q received from the distribution device 30. Next, the information terminal causes the sound emitting device 20 to emit a guidance voice V for guiding the user of the facility P to a place where the degree of congestion is low based on the estimated congestion situation.

(11) In each of the above-described embodiments, the voice information D1 transmitted by each terminal device 10A for acquiring the related information R is stored in the storage device 32 (voice table Tb), but the terminal device 10A acquires the related information R. The voice information D1 transmitted at a timing different from the voice information D1 transmitted for the purpose may be stored in the storage device 32. When the terminal device 10A picks up the guidance voice V, the terminal device 10A transmits the voice information D1 to the distribution device 30 in order to acquire the related information R. After that, the terminal device 10A transmits the voice information D1 (and other information) to be stored in the storage device 32 (voice table Tb) to the distribution device 30. For example, a plurality of voice information D1s may be collectively transmitted at a preset time.

(12) In each of the above-described embodiments, the voice information D1 transmitted from each terminal device 10A is stored in the distribution device 30 (voice table Tb), but the voice table Tb (voice table Tb) is stored in the information processing device separate from the distribution device 30. The voice information D1) may be stored. Each terminal device 10A transmits voice information D1 to each of the distribution device 30 and the information processing device. The distribution device 30 stores the related table Ta and transmits the related information R corresponding to the voice information D1 to the terminal device 10A. On the other hand, the storage device of the information processing device stores the voice table Tb including the plurality of voice information D1 received from each terminal device 10A. The provided information Q is transmitted from the information processing device to the terminal device 10B. In the above configuration, the timing of transmitting the voice information D1 to the information processing apparatus is arbitrary. For example, the voice information D1 may be transmitted to the distribution device 30 at the same time, or a plurality of voice information D1s may be collectively transmitted at a preset time. The voice information D1 and information other than the voice information D1 (for example, status information or language information D4) may be transmitted to the information processing apparatus.

(13) In each of the above-described embodiments, the related information acquisition unit 53 acquires the related information R corresponding to the voice information D1 from the related table Ta, but the related information acquisition unit 53 may generate the related information R. For example, the related information R corresponding to the character string is generated from the voice information D1 indicating the character string representing the utterance content of the guidance voice V. That is, it is not essential to store the related table Ta in the storage device 32.

(14) The audio table Tb exemplified in each of the above-described embodiments is also specified as a data structure. That is, the voice table Tb is a data structure including a plurality of voice information D1s, each of which indicates the content of the sound emitted from the sound emitting device 20 and collected by the terminal device 10A, and is a distribution device 30 (information processing device). (One example) is used in the process of generating the provided information Q by using the plurality of voice information D1 included in the data structure.
