201. when receiving a live broadcasting instruction, the terminal collects the audio data and images of the target object in real time and sends the audio data and images collected in real time to the server.
The live broadcasting instruction is used for indicating audio data and images when the target object sing the target song is live broadcasting.
In this step, when the terminal receives the live broadcasting instruction, the terminal starts the camera and the audio input device to start to collect the image and audio data of the target object in real time, and sends the collected image and audio data of the target object to the server in real time, so that the server sends the image and audio data of the target object to the terminals of a plurality of users watching the target object. The user can trigger a live instruction of the terminal in the video application: when the video application is started, the terminal may display a live button on the current interface. And when the terminal detects that the live button is triggered, the terminal receives the live command.
Further, when the terminal receives the live broadcasting instruction, the terminal acquires the accompaniment audio of the target song and plays the accompaniment audio of the target song, so that the target object can sing the target song along with the accompaniment audio.
It should be noted that a video application may be installed on the terminal, and the terminal performs live video in the video application and performs data interaction with the server based on the video application. The video application can be a live broadcast application with a video live broadcast function, a short video application or a social application and the like. The server may be a background server for the video application. In the embodiment of the invention, the terminal can send the audio data and the image recorded in real time to the server, and the server pushes the audio data and the image to a plurality of users watching the target object to sing.
202. In the live broadcasting process, the terminal determines the score of the audio data collected in real time.
When the terminal collects the audio data, the terminal can analyze the audio data collected in real time to determine the score of the audio data. The terminal can store original singing audio data of the target song in advance, and according to the original singing audio data and the audio data of the target object collected in real time, the audio data collected in real time are scored according to a preset scoring rule.
The preset scoring rule may be set based on needs, which is not specifically limited in the embodiment of the present invention. The terminal can score the audio data corresponding to each lyric by taking one lyric as a unit. The preset scoring rule may be: the higher the similarity between the audio data corresponding to each lyric collected in real time and the audio data corresponding to each lyric in the original singing, the higher the score of the audio data collected in real time.
In a possible implementation, the audio data may also be scored by the server, and the terminal obtains the score of the audio data collected in real time from the server. The process may be: in the live broadcast process, when the server receives real-time collected audio data sent by the terminal, the server scores the real-time collected audio data according to a preset scoring rule based on the real-time collected audio data and sends scores of the real-time collected audio data to the terminal, and the terminal receives the scores of the audio data sent by the server.
Further, in the live broadcasting process, the terminal can further judge and determine whether the score of the audio data collected in real time meets a preset score condition based on the score of the audio data collected in real time. The process may be: and the terminal acquires a preset score condition corresponding to the target song from the server, and judges whether the score of the audio data acquired in real time meets the preset score condition or not according to the score of the audio data acquired in real time.
The preset score condition may be that the score of the audio data is not less than a preset threshold, or the scores of at least a preset number of audio segments in a plurality of audio segments sung by the target object are not less than the preset threshold, and one audio segment may be the audio data corresponding to one lyric sung by the target object. Alternatively, the preset score condition may also be set based on needs, and this is not specifically limited in the embodiment of the present invention.
The terminal can determine the score of each audio segment sung by the target object according to the audio data collected in real time, count the scores of the multiple audio segments in real time, and determine that the score of the audio data collected in real time meets a preset score condition when the scores of the preset number of audio segments in the multiple audio segments are not less than the preset threshold value.
The terminal can acquire audio data of the target object during singing through the audio input device, when the target object performs singing along with the accompanying audio, the terminal can also acquire the audio data of the accompanying audio, at the moment, when the terminal acquires the audio data acquired by the audio input device, the terminal extracts the audio data of a voice frequency band from the audio data according to the frequency band where the voice is located, so that the follow-up judgment and special effect addition are performed only on the basis of the audio data of the voice frequency band, and the accuracy of generating the video file is further improved.
In a possible implementation manner, the terminal may first determine whether the audio data of the target song sung by the target object is true according to the audio data collected by the audio input device, and when the audio data of the target song sung by the target object is true, the terminal performs the step of determining the score of the collected audio data. The real singing means that the target object sings by using the voice of the target object on site, and when the target object plays the target song sung by other people through the playing equipment, for example, when the original singing is played, the target object is not the real singing. Specifically, the terminal extracts voice data of a voice frequency range from the voice data collected by the voice input device according to the frequency range where the voice is located, and when the extracted voice data of the voice frequency range meets a real singing condition, the terminal determines that the target object is real singing. Otherwise, the target object is determined not to be a true song. The real singing condition may be set based on a need, which is not specifically limited in the embodiment of the present invention, for example, the real singing condition may be that the duration corresponding to the extracted audio data of the vocal range reaches a preset duration, or the pitch corresponding to the audio data of the vocal range reaches a preset pitch, or the like. The preset duration or the preset pitch may be set based on a duration or a pitch corresponding to the original singing of the target song in the audio data segment, which is not specifically limited in the embodiment of the present invention.
203. And when the score of the audio data collected in real time meets a preset score condition, the terminal receives a gift sending instruction.
