[0014] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although some embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided to more thoroughly and completely understand the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0015] It should be noted that the titles of any sections / subsections provided herein are not restrictive. Various embodiments are described throughout this document, and any type of embodiment can be included under any section / subsection. Additionally, the embodiments described in any section / subsection can be combined with any other embodiments described in the same section / subsection and / or different sections / subsections in any manner.

[0016] In the description of the embodiments of the present disclosure, the term "including" and its like shall be understood as an open inclusion, that is, "including but not limited to". The term "based on" shall be understood as "at least partially based on". The term "one embodiment" or "the embodiment" shall be understood as "at least one embodiment". The term "some embodiments" shall be understood as "at least some embodiments". There may also be other explicit and implicit definitions hereinafter. The terms "first", "second", etc. may refer to different or the same objects. There may also be other explicit and implicit definitions hereinafter.

[0017] Embodiments of the present disclosure may involve user data, data acquisition and / or use, etc. All of these aspects comply with the corresponding laws, regulations and related provisions. In the embodiments of the present disclosure, the collection, acquisition, processing, processing, forwarding, use, etc. of all data are carried out on the premise that the user is aware of and confirms. Accordingly, when implementing the embodiments of the present disclosure, the types, usage scopes, usage scenarios, etc. of the data or information that may be involved should be informed to the user and the user's authorization should be obtained in an appropriate manner according to relevant laws and regulations. The specific notification and / or authorization methods may vary according to the actual situation and application scenarios, and the scope of the present disclosure is not limited in this regard.

[0018] In the solutions described in this specification and the embodiments, if personal information processing is involved, it will be processed on the premise of having a legal basis (such as obtaining the consent of the personal information subject, or being necessary for performing a contract, etc.), and will only be processed within the specified or agreed scope. If the user refuses to process personal information other than the necessary information required for the basic functions, it will not affect the user's use of the basic functions.

[0019] In the process of people's information interaction through the Internet, people expect to use high-quality audio processing methods to conveniently achieve the desired voice-changing effect. The traditional audio processing method is to use a voice changer to change the voice. However, the voice changer can only change the speaker's tone in the voiceover scenario. If the input audio is a person singing. The voice-changing effect cannot restore the input singing pitch, and the output will still be voiceover content.

[0020] In view of this, embodiments of the present disclosure propose an audio processing solution. According to this solution, the first audio content corresponding to the singing content in the audio can be converted into a specified tone. The specified tone is a tone existing in the tone library or a tone authorized for use. Thus, on the basis of retaining the tone, the voice-changing effect is improved. For example, it can enable users to hear at low cost what the effect is when their own singing is sung in the tone of other characteristics.

[0021] The following further describes various example implementations of this solution in detail with reference to the accompanying drawings.

[0022] Example environment

[0023] Figure 1 The figure shows a schematic diagram of an example environment 100 in which embodiments of the present disclosure can be implemented. As Figure 1 shown, the example environment 100 may include a terminal device 110.

[0024] In this example environment 100, the terminal device 110 may run a platform that supports audio processing. For example, performing voice-changing processing on the audio. The user 140 can interact with this platform via the terminal device 110 and / or its attached devices.

[0025] In Figure 1 environment 100, if the platform is active, the terminal device 110 can present an interface 150 for supporting interface interaction through the platform.

[0026] In some embodiments, the terminal device 110 communicates with the server 130 to implement the supply of services for the platform. The terminal device 110 can be any type of mobile terminal, fixed terminal or portable terminal, including mobile phones, desktop computers, laptop computers, notebook computers, netbook computers, tablet computers, media computers, multimedia tablets, handheld computers, portable game terminals, VR / AR devices, Personal Communication System (PCS) devices, personal navigation devices, Personal Digital Assistant (PDA), audio / video players, digital cameras / camcorders, positioning devices, television receivers, radio broadcast receivers, e-book devices, game devices, or any combination of the foregoing, including accessories and peripherals of these devices or any combination thereof. In some embodiments, the terminal device 110 can also support any type of user interface (such as a "wearable" circuit, etc.).

[0027] The server 130 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks, and big data and artificial intelligence platforms.

[0028] A communication connection can be established between the server 130 and the terminal device 110. The communication connection can be established by wired or wireless means. The communication connection can include, but is not limited to, a Bluetooth connection, a mobile network connection, a Universal Serial Bus (USB) connection, a Wireless Fidelity (WiFi) connection, etc., and the embodiments of the present disclosure are not limited in this regard. In the embodiments of the present disclosure, the server 130 and the terminal device 110 can implement signaling interaction through the communication connection therebetween.

[0029] It should be understood that the structures and functions of the various elements in the environment 100 are described only for exemplary purposes and do not imply any limitation on the scope of the present disclosure.

[0030] Some example embodiments of the present disclosure will be further described below with reference to the accompanying drawings.

[0031] Example process

[0032] Figure 2 A flowchart of an example process 200 for audio processing according to some embodiments of the present disclosure is shown. The process 200 may be implemented at the terminal device 110. The following will be described with reference to Figure 1 to describe the process 200.

[0033] As Figure 2 shown, at block 210, the terminal device 110 obtains first media content input by the user 140. The first media content includes first audio content corresponding to singing content.

[0034] In some embodiments, the first media content input by the user 140 obtained by the terminal device 110 may be first media content recorded by the user 140. For example, a video taken by the user, or a recorded voice as the first media content. The first media content includes an audio corresponding to singing content. For example, a video taken by the user includes a song sung by the user himself.

[0035] In some embodiments, the first media content input by the user 140 obtained by the terminal device 110 may be first media content uploaded by the user 140. For example, a previous video stored on the terminal device 110, or a previously recorded voice stored as the first media content.

[0036] The following will be described with reference to Figures 3A to 3C to describe the process 200. Figures 3A to 3C A schematic diagram of example interfaces 301 to 303 according to some embodiments of the present disclosure is shown. The interfaces 301 to 303 may be provided by, for example, Figure 1 the terminal device 110 shown.

[0037] As Figure 3A shown, the terminal device 110 obtains that the user 140 records a video on the shooting page, and the video includes first audio content corresponding to singing content. Subsequently, the user 140 clicks on the voice control 311 in the interface 301.

[0038] Based on the click of the user 140, the terminal device 110 will present a selection panel 320. As Figure 3BAs shown, the interface 301 can be, for example, the session interface of a session. The terminal device 110 can display a selection panel 320 in the interface 301. As an example, the selection panel 320 can display timbres of different styles, such as style one 321, style two 322, style three, and so on.

[0039] In some embodiments, the selection panel 320 displayed by the terminal device 110 can provide a first set of candidate effects for processing speech content. For example, when the terminal device 110 obtains the speech content input by the user (such as a voiceover), the selection panel 320 can provide different styles that the speech content can be converted into.

[0040] In some embodiments, the selection panel 320 displayed by the terminal device 110 can also provide a second set of candidate effects for processing singing content. For example, when the terminal device 110 obtains the singing content input by the user, the selection panel 320 can provide different styles that the input singing content can be converted into while retaining its original pitch, rhythm, and so on.

[0041] In some embodiments, the terminal device 110 receives the user's selection of a target effect from the second set of candidate effects, and the target effect corresponds to a target timbre. For example, the terminal device 110 can receive the timbres of different genders or different timbres corresponding to different ages selected by the user from the second set of candidate effects.

[0042] Continuing to refer to Figure 2 , at block 220, the terminal device 110 provides second media content based on the user 140's selection of the target timbre. In some embodiments, the second media content includes second audio content corresponding to the singing content. The second audio content corresponds to the selected target timbre.

[0043] In some embodiments, the second audio content included in the second media content provided by the terminal device 110 retains at least the target audio attributes of the first audio content. The target audio attributes include at least pitch, rhythm, and so on. For example, if the pitch of the first audio content includes key A and key B, the second audio content retains at least key A and key B.

[0044] Taking Figure 3C as an example, the user 140 selects style three 331 as the target timbre on the timbre selection panel 320. The terminal device 110 receives the selection of the user 140 and converts the first audio content in the first media content into the second audio content in the second media content. For example, it changes the voice of the singing in the video uploaded by the user.

[0045] For example, if the terminal device 110 obtains the speech content input by the user, it can change the speech content in different styles. For another example, if the terminal device 110 obtains the singing content input by the user, it can change the singing content in different styles and retain the pitch, rhythm, etc. of the original singing. Based on the user's selection of the target effect, the terminal device 110 calls the server 130 to convert the first audio content and provides the second audio content.

[0046] If the first audio content corresponding to singing included in the first media content of the terminal device 110, the terminal device 110 converts the first audio content into the second audio content by calling the server 130 based on the target timbre selected by the user and provides it to the user. In this way, the second audio content can include the pitch of the first audio input. It can be understood that in this way, the user can hear at low cost what the effect is when their own singing is sung in the timbre of other characteristics.

[0047] The generation of the second audio content is described below. In some embodiments, the terminal device 110 extracts the first audio content corresponding to the singing content from the first media content. Subsequently, the terminal device 110 inputs the first audio content into the target model to obtain the second audio content. In some embodiments, the target model can be a model trained by the server according to the sample data corresponding to the target timbre.

[0048] In some embodiments, the terminal device 110 extracts the background audio content from the first media content. The background audio content is different from the first audio content, and the background audio content corresponds to the accompaniment content. For example, for a video, the background audio content can be the background music of the video. For this video, the first audio content can be the song sung by the user himself. The terminal device 110 generates the second media content by fusing the second audio content and the background audio content.

[0049] In some embodiments, the terminal device 110 obtains the intermediate audio content by fusing the second audio content and the background audio content. The terminal device 110 adjusts the reverberation effect or the volume of the intermediate audio content. In some examples, adjusting the volume of the intermediate audio content includes performing global volume equalization on the intermediate audio content. The terminal device 110 generates the second media content according to the adjusted intermediate audio content.

[0050] In some embodiments, the terminal device 110 can first determine the reverberation parameters according to the first media content. Then, the terminal device 110 adjusts the reverberation effect of the intermediate audio content according to the reverberation parameters.

[0051] For example, the reverberation matching model and the support vector classifier (SVC) model are the models that need to be engineered throughout the entire link. The input and output of the two models are independent of each other and can be processed in parallel. The reverberation matching module is a lightweight convolutional neural network (CNN) and long short-term memory network (LSTM) module, which generally finishes running earlier than the SVC model. The reverberation matching model is only responsible for calculating the reverberation parameters from the original user's voice (the output is 3 scalars). The actual addition of audio reverberation is completed by the central processing unit (CPU) in the last step before the link output. The biggest difference between the overall link and the VC link should be the logic of reverberation matching and volume equalization, as well as the additional robust model voice pitch extractor (RMVPE f0 extractor) for polyphonic music.

[0052] Embodiments of the present disclosure obtain first media content input by a user, where the first media content includes first audio content corresponding to singing content; and provide second media content based on the user's selection of a target timbre, where the second media content includes second audio content corresponding to the singing content, and the second audio content corresponds to the selected target timbre. In this way, embodiments of the present disclosure can convert the first audio content corresponding to the singing content in the audio into a specified timbre, thereby improving the voice-changing effect while preserving the timbre.
