Here, the platform may refer to the platform provided by the server 400, which has been previously described with reference to FIG. 2. In more detail, the service providing device participates in contest content implemented in the metaverse space provided through the platform. This may mean obtaining avatar voice information of a target implemented as an avatar and original sound source information related to the sound source provided by the avatar.

Here, the specific process of performing an information acquisition procedure to obtain avatar voice information of a target implemented as an avatar to participate in contest content on the service provision device and original sound source information related to the sound source scheduled to be provided by the avatar in contest content is It can be described in more detail below with reference to FIG. 4.

Figure 4 is a flowchart illustrating a method of performing an information acquisition procedure in an NFT-based service provision method provided in connection with an avatar of contest content implemented in the metaverse space according to an embodiment of the present invention.

Referring to FIG. 4, a service providing device that performs an NFT-based service providing method provided in connection with an avatar of contest content implemented in the metaverse space according to an embodiment of the present invention is a service providing method of a user accessing the metaverse space. It is possible to detect a user terminal, which is a device, and request and obtain avatar voice information including frequency information of the voice output through the avatar for participating in contest content through the user terminal (S110).

Here, the user terminal may refer to the user terminal 300, which has been previously described with reference to FIG. 2, and more specifically, accesses the metaverse space provided through a platform operated or managed by the server 400. It may refer to a possible user's device.

Specifically, when the service providing device detects at least one user requesting the implementation of an avatar among a plurality of users connected to the metaverse space while contest content is provided by the server, the device of the detected at least one user A user terminal can request avatar voice information related to an object to be implemented as an avatar in the metaverse space. Thereafter, the user terminal, which is at least one user's device, may receive a request for avatar voice information related to the target to be implemented as an avatar of contest content implemented in the metaverse space from the service providing device.

Afterwards, the service providing device can request and obtain scheduled sound source information including the name, composer, and lyricist information of the sound source scheduled to be provided in the contest content through the metaverse space through the detected user terminal through its avatar ( S120).

Specifically, the service providing device may request the name, composer, and lyricist information of the sound source desired to be provided (sound source scheduled to be provided) through the avatar of the contest content implemented in the metaverse space through the user terminal. Accordingly, the user terminal can receive a request for the name of the sound source (sound source scheduled to be provided), composer, and lyricist information from the service providing device through the avatar in the metaverse space.

Thereafter, the user terminal may transmit the name, composer, and lyricist information of the sound source desired to be provided (sound source scheduled to be provided) through the avatar in the metaverse space to the service providing server. Accordingly, the service providing device can acquire scheduled sound source information by receiving the name, composer, and lyricist information of the sound source (sound source scheduled to be provided) desired to be provided through an avatar in the metaverse space from the user terminal.

Thereafter, the service providing device may search and obtain original sound source information related to the original song corresponding to the scheduled sound source information in the database of the platform where information on a plurality of original sound sources is stored (S130).

Here, the original sound source information may include frequency information of the voice possessed by the original singer corresponding to the scheduled sound source.

Specifically, the service providing device is a server that may refer to a device that operates or manages a platform using the name of the sound source, composer, and lyricist information that can be confirmed based on the scheduled sound source information (e.g., see Figure 2). A search can be performed in the database included in the server 400, as previously described, and original music source information can be obtained based on the search results.

For example, the database may pre-store information on the names, composers, and lyricists of a plurality of original songs, as well as information on the frequency of the singer's voice for each original song. At this time, information about each original song pre-stored in the database according to an embodiment of the present invention may be referred to as original song information.

In particular, the service providing device can search the database for original songs having the same sound source name, composer, and lyricist information as the name of the sound source that can be confirmed based on the scheduled sound source information, and information on the composer and lyricist. By extracting the matched frequency information, the original sound source information can be obtained.

Referring again to FIG. 3, a service providing device that performs an NFT-based service providing method provided in connection with an avatar of contest content implemented in a metaverse space according to an embodiment of the invention according to an embodiment of the present invention is Based on the avatar voice information and the original music source information, the degree of compatibility between the avatar and the sound source provided through the avatar is converted into a value, and the response rate is the degree of response to each sound source provided while the contest content is provided. The standard calculation procedure can be performed (S200).

Here, the service providing device converts the degree to which the avatar and the sound source provided through the avatar match each other into a value based on the avatar voice information and the original music source information, and calculates the degree of compatibility with each sound source provided while the contest content is provided. The specific process of performing the standard calculation procedure for calculating the degree of response, which is the degree of response to the response, can be described in more detail below with reference to FIG. 5.

Figure 5 is a flowchart illustrating a method of performing a standard calculation procedure in an NFT-based service provision method provided in connection with an avatar of contest content implemented in the metaverse space according to an embodiment of the present invention.

Referring to FIG. 5, a service providing device that performs an NFT-based service providing method provided in connection with an avatar of contest content implemented in the metaverse space according to an embodiment of the present invention includes avatar voice information and original song voice information. Based on the similarity of the included frequency values, the voice similarity between the avatar and the original singer can be calculated as the degree of correspondence between the avatar and the sound source provided through the avatar (S210).

Here, the service providing device may calculate the similarity between the value of the frequency information for the avatar's voice included in the avatar voice information and the value of the frequency information for the original singer's voice included in the original song voice information. For example, a service providing device may calculate similarity based on a preset algorithm available to calculate similarity for a numerical value.

In other words, the service providing device can calculate voice similarity, which can mean the similarity between the voice characteristics of the avatar and the voice characteristics of the original singer who actually provided the sound source to be provided through the avatar.

In other words, the service providing device can calculate the degree of compatibility, which can mean the degree to which the avatar and the sound source to be provided through the avatar match each other, based on voice similarity. For example, if the degree of matching is high, it may mean that the avatar and the sound source to be provided through the avatar match each other to a high degree. On the other hand, if the degree of matching is low, it may mean that the degree of matching between the avatar and the sound source to be provided through the avatar is low.

Afterwards, the service providing device outputs information through the avatar corresponding to each user from a plurality of user terminals, which are devices of a plurality of users connected to the metaverse space, during the entire time that the sound source is provided through a plurality of avatars in the metaverse space. Total feedback information, which is speech information including one or more of information about the uttered content in the form of a sound and information about the intensity of the uttered voice, can be collected (S220).

Afterwards, the service providing device can calculate the response by analyzing the content of the feedback information for each sound source extracted by dividing the feedback information for each time each sound source is provided from the total feedback information for the entire time (S230).

Specifically, the service providing device can extract feedback information for each sound source by extracting feedback information for the time when each sound source is provided from the overall feedback information for the entire time, and can positively respond to the utterance information of the feedback information for each sound source. In order to determine a positive response, the response level of feedback information for each avatar can be calculated based on preset keywords and/or voice intensity.

That is, the service providing device can divide the entire feedback information by the time the sound source is provided through each avatar and generate a plurality of feedback information for each sound source. Afterwards, the service providing device can extract feedback information for each sound source for the avatar for which responsiveness is required from among the feedback information for each sound source generated by dividing the total feedback information by the time the sound source is provided through each avatar. .

Then, for example, the service providing device uses a plurality of keywords such as 'great', 'great', 'cool', and 'impressed', which are text-type keywords that can mean a positive response, to judge them as a positive response. You can pre-set it with keywords. Additionally, the service providing device may preset the voice intensity that can indicate a positive response in a range that is higher than the voice intensity range of a natural person's voice conversation.

Accordingly, the service providing device can calculate the degree to which the speech information of the feedback information for each sound source satisfies the preset keywords and voice intensity as the responsiveness of the feedback information for each sound source.

For example, the service providing device can calculate the number of times a preset keyword is included among the information about the content uttered in voice form from the utterance information of the feedback information for each sound source, and calculate the number of times a preset keyword is included in the information about the content uttered in the form of voice. The difference between the set voice strengths can be calculated. Thereafter, the service providing device may calculate the responsiveness of feedback information for each sound source based on the calculated number of times and the calculated difference.

At this time, the service providing device can calculate a higher response rate as the number of times a preset keyword is included among the information about the content uttered in voice form in the utterance information of the feedback information for each sound source, and information about the intensity of the uttered voice. The smaller the difference between the intensity of the voice and the preset voice, the higher the response rate can be calculated.

Meanwhile, the service providing device can calculate the ratio of a preset keyword among a plurality of keywords with a text type included in the information about the content uttered in voice form as keyword responsiveness, and provide feedback for each sound source of the calculated keyword responsiveness. It can also be reflected in the information.

Again, referring to FIG. 3, a service providing device that performs an NFT-based service providing method provided in connection with an avatar of contest content implemented in the metaverse space according to an embodiment of the present invention uses the calculated degree of conformity and/or The average value between the calculated response values is compared with a preset value as a standard for judging that it is worth issuing a blockchain-based NFT, and the number of blockchain-based NFTs issued among the plurality of music sources provided in the contest content is calculated. An NFT issuance procedure can be performed to issue a blockchain-based NFT for at least one sound source that matches the value (S300).

Here, the average value between the values of conformity and/or calculated response calculated from the service providing device is compared with a preset value as a standard for determining that it is valuable for issuing a blockchain-based NFT in the metaverse space. The specific process of performing the NFT issuance procedure of issuing a blockchain-based NFT for at least one sound source that matches the value of blockchain-based NFT issuance among the plurality of sound sources provided is detailed below with reference to Figure 6. It can be explained clearly.

Figure 6 is a flowchart illustrating a method of performing an NFT issuance procedure in an NFT-based service provision method provided in connection with an avatar of contest content implemented in the metaverse space according to an embodiment of the present invention.
