Step 202: and scoring the singing audio data based on the preset dimension to obtain a scoring result.
Here, the predetermined dimension may include at least one of: tone accuracy; pitch of the sound; word spitting; a vibrato; emotion, etc.
For example, the scoring results may include individual scores for each predetermined dimension or a composite score for each predetermined dimension.
Examples are: the scoring result may include at least one of:
(1) accuracy of sound scoring
The intonation score is used for judging whether the singer accurately grasps the melody of the song. The intonation score of the singer may be calculated based on a predetermined intonation score algorithm. In addition, a intonation score threshold value can be set, and when the intonation score of the singer is lower than the intonation score threshold value, the condition that the intonation skill of the singer is deficient is judged.
(2) Pitch score
Pitch refers to the sound of various heights, i.e., the height of a tone, and is one of the basic characteristics of a tone. The sound level is determined by the vibration frequency, and the sound level and the vibration frequency are in positive correlation: the frequency (i.e., how many times the vibration is performed per unit time) is high, the sound is "high", and otherwise, the sound is "low". The singer's pitch score may be calculated based on a predetermined pitch scoring algorithm. In addition, a pitch score threshold value can be set, and when the pitch score of the singer is lower than the intonation score threshold value, the tone pitch skill of the singer is judged to be deficient.
(3) Trill scoring
Similarly, a vibrato score for the singer may be calculated based on a predetermined vibrato scoring algorithm. In addition, a trill score threshold value can be set, and when the trill score of the singer is lower than the trill score threshold value, the defect of the trill skill of the singer is judged.
(4) Sentiment scoring
Similarly, the emotion score of the singer may be calculated based on a predetermined emotion scoring algorithm. In addition, an emotion score threshold value can be set, and when the emotion score of the singer is lower than the emotion score threshold value, the fact that the emotion skill of the singer is lack can be judged.
(5) Score for telling words
The spitting score is used for judging the word biting definition degree. Similarly, a vocalization score for the singer may be calculated based on a predetermined vocalization scoring algorithm. In addition, a threshold value of the word spitting score can be set, and when the word spitting score of the singer is lower than the threshold value of the word spitting score, the singer is judged to be lack of emotional skills.
(6) And comprehensive scoring
The composite score can be a composite weighted result of individual dimension scores such as intonation score, pitch score, vibrato score, pronoun score and emotion score.
While typical examples of individual scores for predetermined dimensions or composite scores for each predetermined dimension are described above in detail, those skilled in the art will appreciate that this description is merely exemplary and is not intended to limit the scope of embodiments of the present invention.

The song attribute information may include song related attributes such as a song name and a singer name.
Here, when the scoring result is only included as a single dimension score, the predetermined threshold value of step 203 may be implemented as a predetermined threshold value of the single dimension. For example, when the scoring result only includes the intonation score, the predetermined threshold may be implemented as a predetermined threshold of the intonation score. And when the intonation scoring result is lower than a preset threshold value, generating a two-dimensional code containing song attribute information and the intonation scoring result, and displaying the two-dimensional code.
When the scoring result includes a plurality of dimension scores, the predetermined threshold value in step 203 may be implemented as a plurality of threshold values corresponding to the plurality of dimensions. And when the score of any dimension is lower than the corresponding threshold value, generating a two-dimensional code containing song attribute information and the scoring result (namely the scoring result of multiple dimensions), and displaying the two-dimensional code.
When the scoring result includes a plurality of dimension scores and a composite score, the predetermined threshold value in step 203 may be implemented as a plurality of threshold values and a composite score threshold value corresponding to the plurality of dimensions. And when the score of any dimension is lower than the corresponding threshold or the comprehensive score is lower than the comprehensive score threshold, generating a two-dimensional code containing song attribute information and score results (namely the score results and the comprehensive score of multiple dimensions), and displaying the two-dimensional code.
The finally generated and displayed two-dimensional code is the singing scoring two-dimensional code, and can be subsequently used for scanning by a user to improve the singing level.
The above describes a specific embodiment of obtaining the scoring result by taking the two-dimensional code as an example, and those skilled in the art will appreciate that this description is only exemplary and is not intended to limit the scope of the embodiments of the present invention.
