Description

[0001] The present application claims the priority of China Patent Application No. 201910152655.3, filed with the National Intellectual Property Administration of China on February 28, 2019, entitled "SONG RECORDING METHOD, AUDIO CORRECTION METHOD, AND ELECTRONIC DEVICE", which is hereby incorporated by reference in its entirety.

FIELD OF TECHNOLOGY TO WHICH THE INVENTION RELATES

[0002] The present invention relates to the field of audio technology, and in particular, to a song recording method, a sound correction method, and an electronic device.

BACKGROUND OF THE INVENTION

[0003] For a user who loves to sing, the karaoke application has become a popular application to be installed on an electronic device such as a mobile phone or a tablet computer. For example, by opening a karaoke application, the user can select a song to be recorded. In addition, the karaoke application can download the song's accompaniment and invoke a pickup component such as a microphone on a mobile phone to record the sound received after the user sings the song, thereby integrating the user's own singing voice into the accompaniment provided by the karaoke application.

[0004] At present, in order to improve a user's singing when using a karaoke application, some karaoke applications provide an audio correction feature for a song recorded by the user. For example, a karaoke application can compare the user-recorded song A with the original audio of song A, and change the intonation and rhythm of the user-recorded singing voice to the intonation and rhythm of the original audio, thereby correcting intonation and rhythm problems that occur when song recording by the user.

[0005] However, in addition to problems with intonation and rhythm, the average user, as a rule, does not have a professional musical education in the field of vocals. Therefore, a user with insufficient singing skills still cannot achieve a good recording effect when recording a song.

SUMMARY OF THE INVENTION

[0006] The present invention provides a song recording method, a sound correction method, and an electronic device to instruct a user to use an appropriate singing skill when the user records a song, thereby improving the recording effect and usability when the user uses a karaoke application.

[0007] To achieve the above goal, the following technical solutions are used in this application.

[0008] According to a first aspect, the present invention provides a method for recording a song, comprising: displaying a first interface by an electronic device, the first interface comprising a record button used to record the first song; if it is detected that the user presses the record button, obtaining the accompaniment electronic device of the first song and a cappella characteristic information of the original singer, wherein the a cappella characteristic information of the original singer can be used to reflect the singing characteristic of the original singer when the original singer sings the first song; further, starting the accompaniment electronic device of the first song, and starting the user's a cappella recording that the user sings; and in the user's a cappella recording process, displaying the electronic device guide information on the second interface based on the original singer's a cappella characteristic information, the guide information being used to instruct the execution of one or more of the breath and vibrato while the user sings. In other words, when the user records a song, the electronic device can display guidance information based on the original singer's singing characteristic to instruct one or more singing skills such as breathing or vibrato while the user sings, thereby improving the recording effect and use experience. when the user records the song.

[0009] In an exemplary implementation, the original singer's a cappella characteristic information contains a breath location in the original singer's a cappella, in which case the guide information may include a breath prompt.

When making a call or sending voice information, the user may make a sound by approaching the microphone 170C with his mouth to input an audio signal into the microphone 170C. One or more microphones 170C may be located in the electronic device 100. In some other embodiments of the invention, two microphones 170C may be located in the electronic device 100 and may additionally implement a noise cancellation function in addition to collecting the audio signal. In some other embodiments of the invention, three, four or more microphones 170C may alternatively be located in the electronic device 100 to collect the audio signal, reduce noise and additionally identify the source of the sound, as well as to implement the function of directional recording, etc.

[0095] In this embodiment of the invention according to the present application, when the electronic device 100 starts the karaoke application, the microphone 170C can be used to collect the user's a cappella, more specifically, a pure human voice without music when the user sings the song. In addition, the audio module 170 may use an appropriate audio correction algorithm to correct the user's collected a cappella.

[0096] For example, if a relatively obvious or erratic breath sound appears in a user's a cappella in song A recorded by a user, the audio module 170 may perform breathing sound attenuation processing at a corresponding location in the user's a cappella to improve the listening experience of the song.

[0097] As another example, if vibrato appears in the original artist's a cappella of song A, audio module 170 may determine if vibrato is also used at the corresponding user a cappella location of song A recorded by the user. If the vibrato effect used by the user is not good, the audio module 170 may correct the vibrato at the appropriate location a cappella of the user to improve the listening experience of the song.

[0098] As another example, audio module 170 can identify, by comparing song user A's a cappella with the original singer's a cappella, the location at which "out of tune" occurs in the user's a cappella, and furthermore, the audio module 170 may perform an appropriate pitch up or down at the point where "out of tune" occurs in the user's a cappella, thereby correcting the intonation problem in the user's a cappella. The specific correction method by the user a cappella electronic device 100 that is picked up by the microphone 170C is described in detail in the following embodiment. Therefore, the details are not described here.

[0099] It can be recognized that in this embodiment according to the present application, in addition to calibrating intonation for a song recorded by a user, the electronic device can further solve a problem of singing skills such as breathing or vibrato in a song recorded by a user. Thus, a general user who does not have a professional music education in the field of vocals can also record a singing voice with a relatively good listening quality, thereby improving the recording effect and usability when the user uses the karaoke application.

[0103] The electric motor 191 may generate a vibration prompt. The motor 191 may be used to vibrate on an incoming call, and may also be used for touch vibration feedback. For example, touch operations performed in different applications (such as taking photos and playing audio) may correspond to different vibration feedback effects. The electric motor 191 may also correspond to different vibration feedback effects for touch operations performed in different areas of the display 194. Different application scenarios (eg, time reminder, get information, alarm clock, and game) may also correspond to different vibration feedback effects. Optionally, a vibration touch feedback effect setting can be supported.

[0104] The indicator 192 may be an indicator light that may be used to indicate charging status and power change, or may be used to indicate a message, missed call, notification, or the like.

[0105] The SIM card interface 195 is configured to be connected to a SIM card.

[0106] The software system of the electronic device 100 may use a hierarchical architecture, an event-driven architecture, a microprocessor architecture, a microservices architecture, or a cloud architecture. In this embodiment of the present application, the hierarchical Android system is used as an example to illustrate the software structure of the electronic device 100.

[0107] FIG. 2 is a block diagram of the software structure of an electronic device 100 according to an embodiment of the invention according to the present application.

[0108] In a hierarchical architecture, the software is divided into several layers, and each layer has a clear role and task. The levels interact with each other through a software interface. In some embodiments of the invention, the Android system is divided into four levels, namely the application program level, the application structure level, the Android runtime and the system library, and the kernel level from top to bottom.

[0109] The application program layer may include a number of application packages.

[0110] As shown in FIG. 2, the application package may include applications (application), such as calls, contacts, camera, gallery, calendar, map, navigation, Bluetooth, music, video and messages.

[0111] In this embodiment of the invention according to the present application, a karaoke application such as the "Changba" application or the "WeSing" application may be further installed at the application level. The user can record a song through the karaoke application and integrate the user's singing voice into the accompaniment provided by the karaoke application.

[0112] The application program structure layer provides an application programming interface (API) and a programming structure for an application program at the application program level. The application structure layer includes some predefined functions.

[0113] As shown in FIG. 2, the application structure layer may include a window manager, a content provider, a presentation system, a resource manager, a notification manager, and the like.

[0114] The window manager is configured to manage a window program. The window manager can get the display size and determine if there is a status bar, lock screen, screen capture, and the like. The content provider is configured to: store and receive data and provide access to the data to the application program. The data may include video, image, audio, calls made and answered, browsing history and bookmark, address book, and the like. The presentation system includes a visual control such as a control for displaying text and a control for displaying an image. The presentation system may be configured to create an application program. The display interface may include one or more views. For example, the display interface including the short message service notification icon may include a view for displaying text and a view for displaying an image. The resource manager provides various resources such as a localized character string, an icon, an image, a layout file, and a video file for an application. The notification manager allows an application to display notification information in a status bar and may be configured to send a notification type message. The notification type message may automatically disappear after a short pause and no user interaction is required. For example, the notification manager is configured to notify the completion of a download, display a message, and the like. Alternatively, the notification manager may be a notification that appears on the top system status bar in the form of a graphic or scroll bar text, such as a notification about an application running in the background, or may be a notification that appears on the screen as a dialog box. For example, text information is requested in the status bar, an audible signal is emitted, an electronic device vibrates, or an indicator light flashes.

[0115] The system library may include a plurality of functional modules, such as a surface manager (surface manager), a multimedia library (Media Libraries), a 3D graphics processing library (for example, OpenGL ES) and a 2D graphics engine (for example, SGL) .

[0116] The surface manager is configured to: control the display subsystem and provide a combination of two-dimensional and three-dimensional levels for a variety of application programs. The media library supports the playback and recording of many widely used audio and video formats, still image file, and so on. The media library can support many audio and video encoding formats such as MPEG4, H.264, MP3, AAC, AMR, JPG, and PNG. The 3D graphics processing library is configured to implement 3D graphics drawing, image rendering, composition, level processing, and the like. The 2D graphics engine is a drawing engine for 2D drawing.

[0117] In this embodiment of the invention according to the present application, as shown in FIG. 2, the corresponding sound correction algorithm provided in this embodiment according to the present application can be installed in the system library in the form of a dynamic link library (DLL). For example, a library of dynamic sound correction algorithms may be stored in the system/lib directory. When a karaoke application is launched at the application level, the karaoke application can call the audio correction algorithm dynamic algorithm library to correct a problem such as intonation, vibrato, or a cappella breathing sound of the user, thereby realizing the audio correction function.

[0118] The Android runtime includes a kernel library and a virtual machine. The Android runtime is responsible for scheduling and managing the Android system.

[0119] The core library includes two parts: a function to be called by the Java language, and an Android core library.

[0120] The application program layer and the application structure layer are executed in a virtual machine. The virtual machine executes java files at the application program level and at the application structure level as binary files. The virtual machine is configured to perform functions such as object lifecycle management, stack management, thread management, security and exception management, and garbage collection.

[0121] The kernel level is the level between hardware and software. The kernel level includes at least a display driver, a camera driver, an audio driver, a sensor driver, and the like. This is not limited in this embodiment of the invention according to the present application.

[0122] The mobile phone is used as an example of an electronic device below to describe in detail the song recording method and the sound correction method presented in the embodiments of the invention according to the present application, with reference to the accompanying drawings. As shown in FIG. 3, the method includes the following steps S301 to S306.

[0123] S301. When the karaoke application is started, the mobile phone receives a user selection operation to record song A.

[0124] A karaoke application is an application software that can provide a user with functions such as song request, song recording, and audio editing. For example, the karaoke application may be the "WeSing" application or the "Changba" application. This is not limited in this embodiment of the invention according to the present application.

[0125] If the mobile phone detects the operation of opening the karaoke application by the user, as shown in FIG. 4, the mobile phone can start running the karaoke application and display the first interface 401 of the karaoke application. The user can search the first interface 401 for a song he likes and record the song. Alternatively, the user may manually search the search bar 402 and select the song to be recorded. Of course, the user may alternatively select, on another screen of the karaoke application, the song to be recorded this time. This is not limited in this embodiment of the invention according to the present application.

[0126] However, as shown in FIG. 4, if the user wants to record the song "Red Bean", the user can press the record button 403 for the song "Red Bean" on the first interface 401. In this case, the mobile phone can receive a user selection operation to record the song "Red Bean". In response to the operation of the user selecting the recording of the "Red Bean" song, the mobile phone may continue to perform the following steps S302 to S306 to complete processes such as recording and audio editing of the song.

[0127] S302. The mobile phone receives the accompaniment of song A and contains the a cappella characteristic information of the original singer.

[0128] The user's recording of the song "Red Bean" is still used as an example. Upon detecting that the user presses the record button 403 for the song "Red Bean", the mobile phone can download the accompaniment of the song "Red Bean" from the server. Of course, if the mobile phone saves the accompaniment of "Red Bean" this time, the mobile phone can get the accompaniment from the local memory. Usually, a part of the song, except for the human voice, may be called an accompaniment, and some of the accompaniment may additionally include harmony, background sound, and the like.

[0129] In this embodiment according to the present application, after detecting that the user presses the record button 403 for the song "Red Bean", the mobile phone can further download the a cappella characteristic information of the original artist of the song "Red Bean" from the server. The characteristic information may reflect the singing characteristics of the original singer (eg, Faye Wong) when performing the song "Red Bean". For example, the characteristic information may include one or more of information about the fundamental frequency, breath position, and a cappella vibrato characteristic of the original singer. The vibrato characteristic may include one or more of a vibrato location, vibrato fundamental frequency stability information, vibrato frequency, and vibrato amplitude.

[0130] The fundamental frequency information may reflect the fundamental tone of the sound. As shown in FIG. 5, the server can extract the fundamental time-frequency change curve f(t) frame by frame from the a cappella of the original singer of the song "Red Bean" in advance, and the variation curve f(t) is information about the fundamental frequency of the song "Red Bean". However, as shown in FIG. 5, the server may further detect the place where the original singer breathes in the original singer's a cappella, and use as one piece of information the characteristics of the moment when the original singer breathes. Just as shown in FIG. 5, the server may further detect the location at which the vibrato appears in the original singer's a cappella, and use the vibrato occurrence timing characteristics as one piece of information.

[0131] Typically, vibrato appears as periodic changes in pitch. Three time-varying characteristics, namely vibration amplitude A(t), vibration frequency Φ(t), and stable trend time V(t), can be extracted from the fundamental frequency curve by means of a vibrato characteristic. For example, vibrato 1 appears in the third a cappella sentence of the original artist of the song "Red Bean". The fundamental frequency curve corresponding to vibrato 1 is f3(t) = V(t) + A(t) cos(Φ(t)), where t is within [8s, 10s]. V(t) is vibrato 1 fundamental frequency stability information, Φ(t) is vibrato 1 vibrato frequency, and A(t) is vibrato 1 vibrato amplitude. The server can send fundamental frequency stability information, vibrato frequency and the amplitude of the vibrato of each vibrato in the song "Red Bean" as characteristic information.

[0132] For example, each time a new song is added to the song library on the server, the server may extract the corresponding feature information based on the a cappella original singer of the new song, and store the extracted feature information on the server. Subsequently, if the user decides to record the song on the mobile phone, the mobile phone can obtain the accompaniment of the song from the server, and can further obtain from the server the a cappella characteristic information of the original singer corresponding to the song. The obtained a cappella characteristic information of the original singer can be used to guide the user when recording a song, and can also be used as the basis for sound correction to correct a song recorded by the user.

[0133] S303. When the recording interface of the karaoke application is displayed, the mobile phone plays the accompaniment of song A and records the user's a cappella that the user sings.

[0134] The user's recording of the song "Red Bean" is still used as an example. After the mobile phone receives the accompaniment of the song "Red Bean", the mobile phone can start playing the accompaniment of the song "Red Bean". In addition, the mobile phone may allow the microphone to start the user's a cappella recording, which is obtained after the user sings the song "Red Bean".

[0135] As shown in FIG. 6, in the process of recording the song "Red Bean", the mobile phone can display the recording interface 601 of the song "Red Bean". The record interface 601 may display the lyrics 602 of the "Red Bean" song, and the location of the recorded lyrics can be marked in real time in the lyrics 602, so that the user can record the song based on the clue in the lyrics 602.

[0136] S304. When song A is recorded, the mobile phone, based on the original singer's a cappella characteristic information, instructs the user to adjust the singing manner such as intonation, breathing, or vibrato.

[0137] For example, when the user records a song through the karaoke application, when the song lyrics 602 are displayed, the mobile phone can guide the user based on the characteristic information obtained in step S302 to sing the song, for example, guide the user's singing manner such as intonation, breathing or vibrato.

[0138] The user's recording of the song "Red Bean" is still used as an example. The a cappella characteristic information of the user received by the mobile phone includes information such as breathing position and vibrato position. In this case, as shown in FIG. 7, when displaying the lyrics 602 of the song "Red Bean" in real time, the mobile phone can mark the location 701 of the breath (i.e., the breath prompt) in the corresponding location of the lyrics 602 based on the location of the breath recorded in the original singer's a cappella information characteristics. Thus, when recording the song "Red Bean", the user can breathe based on the breath location 701 indicated in the song lyrics 602 to help the user control breathing variations while singing, thereby reducing the relatively obvious and erratic breath sound in the recorded song to improve the quality of listening to the recorded song.

[0139] As another example, as shown in FIG. 7, when displaying the lyrics 602 of the "Red Bean" song in real time, the mobile phone can further mark the vibrato location 702 (i.e., vibrato hint) in the corresponding location of the song lyrics 602 based on the recorded vibrato location in the original singer's a cappella characteristic information. Thus, when recording the song "Red Bean", the user can sing with vibrato based on the vibrato location 702 indicated in the song lyrics 602 to improve the sense of song hierarchy and singing skills when the user sings, thereby improving the listening experience of the recorded song.

[0140] In some other embodiments of the invention, in addition to the guide, in the lyrics displayed in real time to the user for singing, the mobile phone can additionally set the singing tool in the recording interface. The mobile phone in the singing instrument can guide the user in adjusting the manner of singing, such as intonation, breathing, or vibrato.

[0141] The user's recording of the song "Red Bean" is still used as an example. As shown in FIG. 8, when the recording interface 601 is displayed, the mobile phone can set the singing tool 801 on the recording interface 601. The singing tool 801 may display a note for each word in the lyric sentence of the song currently being recorded. For example, the mobile phone may display the pitch line 802 (ie, intonation hint) in the real-time singing tool 801 based on the original singer's a cappella fundamental frequency information. A higher pitch of the current note results in a higher pitch of the tone line 802. As another example, a mobile phone may display a vibrato note 803 (i.e., a vibrato prompt) in the singing tool 801 based on the original singer's a cappella vibrato spot. The vibrato note 803 may be represented by a break line or a line segment of a specific color. The place where the 803 vibrato note appears is the same as the place where the original singer's a cappella vibrato appeared. As another example, if a breath sound appears in the original singer's a cappella corresponding to the current lyric sentence, the mobile phone may display a breath note 804 (i.e., a breath prompt) in the singing tool 801 based on the location of the breath in the original singer's a cappella. The breath note 804 may be represented by a graph of some form, such as a triangle or a circle. The location at which the breath note 804 appears is the same as the location at which the breath sound appears in the original singer's a cappella.

[0142] Thus, when recording a song, the user may adjust the intonation of the human voice based on the pitch line displayed in the live singing tool 801, or may sing with vibrato at the appropriate location based on the vibrato note displayed in the live singing tool 801. real time or can breathe in the appropriate place based on the breath note displayed in the real time singing tool 801 to guide the singing skills such as intonation, vibrato and breathing while the user sings in the recording process, thereby improving the recording quality of the song.

[0143] It can be understood that when the user records a song, in addition to the guide, in the lyrics and the singing tool that are displayed on the recording interface, the user sings, when the user records the song, one skilled in the art can further guide the user based on based on real experience or real application scenario, using the original singer's a cappella characteristics information, how best to sing the song. This is not limited in this embodiment of the invention according to the present application.

[0144] S305. When the song A is recorded, the mobile phone evaluates the user's singing by comparing the original singer's a cappella characteristic information with the user's a cappella characteristic information.

[0145] The user's recording of the song "Red Bean" is still used as an example. When the song "Red Bean" is recorded, the mobile phone can further evaluate the user's current singing in real time based on the a cappella characteristic information of the original singer. For example, the mobile phone may rate the user's singing using a word, phrase, or sentence in the lyrics as the granularity. As shown in FIG. 9A and FIG. 9B, after the mobile phone collects the user's a cappella obtained after the user sings "I believe an end comes at a time", the mobile phone can extract the user's a cappella characteristic information of this sentence. Similar to the original singer's a cappella characteristic information, the mobile phone can first extract the user's a cappella fundamental frequency information of this sentence and detect one or more pieces of characteristic information, such as the user's breathing position, vibrato position, vibrato fundamental frequency stability information, vibrato frequency, and vibrato amplitude based on the user's a cappella fundamental frequency information.

[0146] In this case, by comparing the original singer's characteristic information 1 when singing "I believe an end comes at a time" with the user's characteristic information 2 when singing "I believe an end comes at a time", the mobile phone can determine the result evaluating singing skills such as intonation, vibrato, and breathing of the user while singing this sentence.

[0147] For example, if the difference between the user's a cappella fundamental frequency information and the original singer's a cappella fundamental frequency information is less than a threshold value, it means that the intonation of the user when singing this sentence matches that of the original singer. As shown in FIG. 10(a), the mobile phone may display the "Intonation Expert" prompt 1001 on the recording interface 601 to notify the user that the user sings the sentence correctly intonation. If the user's a cappella vibrato location is the same as the original singer's a cappella vibrato location, and the difference between the vibrato characteristic (more precisely, vibrato frequency, vibrato amplitude, and fundamental frequency stability information) of the user's a cappella vibrato and the corresponding a cappella vibrato characteristic of the original singer is less than the threshold value, this indicates that the vibrato produced by the user while singing this sentence matches the vibrato of the original singer. As shown in FIG. 10(b), the mobile phone may display the "Vibrato Queen" prompt 1002 on the recording interface 601 . If the location of the breath sound in the user's a cappella matches the location of the breath sound in the original singer's a cappella, this indicates that the user's breath adjustment while singing this sentence matches that of the original singer. As shown in FIG. 10(c), the mobile phone may display the "Get breath prompt" prompt 1003 on the recording interface 601 .

[0148] In addition to notifying the user of the current evaluation result in real time via text, the mobile phone can display the current evaluation result in real time to the user using color, vibration, special effect, and the like.

[0149] For example, as shown in FIG. 11(a), if the vibrato used by the user when singing the lyrics of "I believe an end comes at a time" is incompatible with the vibrato used when the original singer sings this sentence, when displaying the "end" 1101 of the lyrics corresponding to the vibrato, the mobile phone may mark the "end" 1101 as a different color from other lyrics, use a different font, and the like. In another example, as shown in FIG. 11(b), if the user's breathing position while singing this sentence is incompatible with the original singer's breathing position while singing this sentence, the mobile phone may flag a breath error mark 1102 when displaying the lyrics corresponding to the breathing position.

[0150] Alternatively, the mobile phone may further display to the user in the singing tool 801 on the recording interface 601 the evaluation result determined by the mobile phone. For example, as shown in FIG. 12(a), when the user sings the word "comes", the mobile phone can not only display in the real-time singing tool 801 the tone line 1201 obtained when the original singer sings "comes", but can also display at the same time , the tone line 1202 obtained when the user sings the word "comes" this time. If the fundamental frequency used when the user sings the word "comes" is lower than the fundamental frequency used when the original singer sings the word "comes", it means that the tone of the user when singing "comes" is lower than the tone of the original singer when singing " comes", and the tone line 1202 displayed by the mobile phone is lower than the tone line 1201. Accordingly, if the user's tone when singing the word "comes" is found to be higher than the original singer's tone when singing the word "comes", the tone line 1202, displayed by the mobile phone may be higher than the tone line 1201. In addition, if the tone of the user when singing the word "comes" is found to be the same as the tone of the original singer when singing the word "comes", the tone line 1202 in the singing tool 801 matches the tone of the tone line 1201. Thus, the user can know the intonation situation of the current singing from the singing tool 801 while singing in real time.

[0151] In another example, as shown in FIG. 12(b), the mobile phone can display in the singing tool 801 the vibrato note 1203 obtained when the original singer sings vibrato 1. After detecting the user's a cappella when the user sings vibrato 1, the mobile phone can determine by comparison, vibrato location, amplitude vibrato A (t), vibrato frequency Φ (t) and stable trend fragment V (t) obtained when the user sings vibrato 1 whether the vibrato location, vibrato amplitude A (t), vibrato frequency Φ (t) and stable trend V (t) obtained when the original singer sings vibrato 1. If the vibrato location, vibrato amplitude A (t), vibrato frequency Φ (t) and the stable trend fragment V (t) obtained when the user sings vibrato 1 do not correspond to the vibrato place, vibrato amplitude A(t), vibrato frequency Φ(t) and stable trend fragment V(t) obtained when the original singer sings vibrato 1, this indicates that the preset vibrato effect is not achieved, to When the user sings vibrato 1 this time, and the mobile phone can display the vibrato note 1203 as a display effect such as a dotted line. Accordingly, if the vibrato place, vibrato amplitude A(t), vibrato frequency Φ(t) and the stable trend fragment V(t) obtained when the user sings vibrato 1 correspond to the vibrato place, vibrato amplitude A(t), vibrato frequency Φ (t) and the stable trend fragment V(t) obtained when the original singer sings vibrato 1, this indicates that the preset vibrato effect is achieved when the user sings vibrato 1 this time, and as shown in FIG. 12(b), the mobile phone can bold or highlight the vibrato note 1203 so that the user can examine the current vibrato singing effect from the singing tool 801 while singing in real time.

[0152] It can be understood that a person skilled in the art can further evaluate based on actual experience or a real application scenario and based on the information of the a cappella characteristics of the original singer and the user cappella that the user sings in real time when recording a song and displays the result evaluating the breath skill, vibrato skill, or intonation skill for the user, for example, the mobile phone can rate the user's a cappella based on the original singer's a cappella characteristic information and display the evaluation result to the user. This is not limited in this embodiment of the invention according to the present application.

[0153] It can be recognized that in this embodiment according to the present application, in the process of recording a user's song, one or more of the user's singing skills, such as intonation, vibrato, or breathing, can be assessed in real time based on the a cappella characteristic information of the original singer. Compared to judging the level of a user's singing based on intonation alone, in this embodiment of the invention according to the present application, factors such as the user's breathing and vibrato are also taken into account during the judging of the user's singing, and therefore the resulting judging result is more accurate, voluminous, and objective. In addition, the mobile phone can return the user's singing evaluation result to the user in real time during the recording process, so that the user knows the current effect of the user's singing in time, and the user can adjust the singing manner in time in the subsequent recording process.

[0154] S306. After the recording of song A is completed, the mobile phone corrects the user's a cappella based on the original singer's a cappella characteristic information and the user's a cappella characteristic information.

[0155] When the mobile phone finishes playing the accompaniment of song A or detects a recording end operation inputted by the user, the mobile phone can turn off the microphone to stop the a cappella collection made by the user. In addition, after the recording of song A ends, as shown in FIG. 13, the mobile phone can display the audio correction interface 1301 of the karaoke application. The sound correction interface 1301 may include a sound correction switch 1302. If it is detected that the user turns on the audio correction switch 1302, the mobile phone can correct, based on the a cappella characteristic information of the original singer of song A, a singing problem (e.g., one or more of the singing problems such as intonation, vibrato, and breath sound), which appears in the user's a cappella and is collected when the user records song A this time.

[0156] For example, the user's recording of the song "Red Bean" is still used as an example. After the user records the song "Red Bean" in the recording interface, the mobile phone can display the audio correction interface 1301 shown in FIG. 13. If it is detected that the user turns on the sound correction switch 1302 on the sound correction interface 1301, the mobile phone can perform correction based on the information of the original singer's a cappella characteristic, intonation, breath sound, and vibrato in the user's a cappella collected this time.

[0157] For example, the mobile phone may compare the original singer's a cappella fundamental frequency information with the fundamental frequency information of the song "Red Bean" recorded this time by the user to correct the intonation problem that appears in the user's a cappella this time. For example, if the tenth to twentieth second tone in the user's a cappella is lower than the tenth to twentieth second tone in the original singer's a cappella, the mobile phone can play the tone: the user's a cappella is the same or close to the original singer's a cappella tone. For example, if the tone from the first minute and twelfth second to the first minute and twenty-seventh second in the user's a cappella is higher than the tone from the first minute and twelfth second to the first minute and twenty-seventh second in the original singer's a cappella, the mobile phone may perform down processing tones for the tone of that user's a cappella part, so that the user's a cappella part's tone is the same as or close to the original singer's a cappella tone.

[0158] As another example, the mobile phone can extract the location of the breath sound from the user's a cappella song "Red Bean" recorded this time by the user. For example, a mobile phone can detect, using a preset breath detection pattern, that breath sound appears at both the fourteenth and seventy-eighth seconds a cappella of the user. In addition, the mobile phone can reduce the user's energy and a cappella frequency response at the fourteenth second and seventy-eighth second, thereby attenuating the breathing sound that appears at the fourteenth second and seventy-eighth seconds, to improve the listening quality of the recorded song.

[0159] As another example, the mobile phone can compare the a cappella vibrato characteristic of the original singer with the vibrato characteristic of the song "Red Bean" recorded this time by the user to correct the vibrato with the user's poor a cappella vibrato effect this time. For example, the mobile phone can detect, using a preset vibrato detection pattern, the location where the vibrato appears in the user's a cappella. For example, vibrato 1 is detected at the fifteenth second in the user's a cappella, and if vibration amplitude A1 (t), vibration frequency Φ1 (t) and a fragment of a stable trend V1 (t) of vibrato 1 are compared with vibration amplitude A2 (t), vibration frequency Φ2 (t) and a fragment of the stable trend V2 (t) vibrato 2 at the fifteenth second a cappella of the original singer, this indicates that the effect of vibrato 1 sung by the user is basically the same as the original singer, and the mobile phone does not need correction of vibrato 1. Accordingly, if the oscillation amplitude A1 (t), the oscillation frequency Φ1 (t) and the stable trend fragment V1 (t) vibrato 1 do not correspond to the oscillation amplitude A2 (t), the oscillation frequency Φ2 (t) and the stable trend fragment V2 (t) vibrato 2 at the fifteenth second of the original singer's a cappella, the mobile phone can synthesize a new user's a cappella vibrato at the fifteenth second, using the vibration amplitude A2 (t), the frequency Φ2 (t) of the vibration and the fragment is stable V2 (t) Vibrato 2 to enhance the vibrato sound effect that appears in the user's a cappella.

[0160] In some embodiments of the invention, as shown in FIG. 14, upon detecting that the user turns on the audio correction switch 1302 on the audio correction interface 1301, the mobile phone can further display the audio correction option 1401 for intonation correction, the audio correction option 1402 for breathing sound correction, and the audio correction option 1403 for vibrato correction. Thus, the user can manually select in the audio correction interface 1301 to correct the intonation problem, the breathing sound problem, or the user's a cappella vibrato problem that is being recorded at this time.

[0161] In some other embodiments, after collecting the user's a cappella song "Red Bean" recorded by the user this time, the mobile phone can further automatically correct problems such as intonation, breathing sound, and vibrato in the user's song a cappella to improve the quality of listening to a song during its subsequent playback. For example, as shown in FIG. 14, a play button 1404 is located on the audio correction interface 1301. If it is detected that the user presses the play button 1404, the mobile phone can automatically correct, based on the information of the original singer's a cappella characteristics, problems such as intonation, breathing sound, and vibrato in the user's a cappella, and integrate the adjusted user's a cappella into the accompaniment of the song "Red Bean" to play.

[0162] In some embodiments of the invention, as shown in FIG. 15(a), a single sentence refinement option 1501 can be further set in the karaoke sound correction interface 1301 of the application. If the user is found to select option 1501, as shown in FIG. 15(b), the mobile phone may display the refinement interface 1502. In the refinement interface 1502, the mobile phone may display each lyric sentence performed by the user in the song "Red Bean" and use each lyric sentence as an option for the user to select. For example, the user selects the lyrics 1503 of the song "I believe an end comes at a time". After the user selects the lyrics 1503 of the song, the mobile phone can play back the recorded portion of the song corresponding to the lyrics 1503 of the song. An intonation button 1504, a vibrato button 1505, and a breath button 1506 are additionally set in the sound correction interface 1301. The user can manually select refinements in the interface 1502 to correct one or more singing problems such as intonation, vibrato, or breath sound that appear in the user's a cappella and match the lyrics 1503 of the song. If the user presses the vibrato button 1525 and the intonation button 1504 after selecting the song lyrics 1503, the mobile phone can correct the intonation problem and the user's a cappella vibrato problem corresponding to the song lyrics 1503 and integrate the user's adjusted a cappella into the corresponding accompaniment for playback. Thus, the user can correct, sentence by sentence, a singing problem that appears in the a cappella of the user recorded this time, and the user can compare, sentence by sentence, the recorded effects achieved before and after the correction to correct the song recorded user with the singing effect that suits the user the most.

[0163] In some other embodiments of the invention, as shown in FIG. 16(a), the single sentence edit option 1601 can be further set in the karaoke sound correction interface 1301 of the application. If the user is found to select option 1601, as shown in FIG. 16(b), the mobile phone may display an edit interface 1602. In the editing interface 1602, the mobile phone can display each lyric sentence performed by the user in the song "Red Bean". In addition, when displaying each sentence of lyrics, the mobile phone can further indicate at the corresponding place in the lyrics a singing problem that occurs when the user sings the lyrics sentence, for example, with an inaccurate tone, a relatively high breath sound, unstable vibrato, or no vibrato. . Thus, the user can intuitively see the specific problem that occurs when the user sings each sentence of the lyrics.

[0164] In addition, as shown in FIG. 16(b), an edit button 1603 corresponding to each sentence of lyrics can be further set in the edit interface 1602. If it is detected that the user presses the edit button 1603 corresponding to a particular sentence of the lyrics, the mobile phone can play the accompaniment corresponding to the lyrics and allows the microphone to collect the user's a cappella obtained after the user re-sings the lyrics. After the mobile phone collects the user's a cappella obtained after the user re-sings the lyrics, and the user's a cappella corresponding to the recorded song "Red Bean" can be replaced by the user's a cappella that is overwritten this time. When the lyrics are displayed in the editing interface 1602, the mobile phone notifies the user of a specific singing problem that occurs when the user sings the lyrics. Therefore, when the user repeatedly sings the lyrics, the user can adjust the singing manner in time to correct the singing problem that occurs when the lyrics are recorded for the last time. This improves the quality of singing and recording.
