Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] The abbreviations that may appear in the specific implementation are explained as follows:

[0029] CQT (constant Q transform): constant Q transform;

[0030] PKPP (Piano Key Posterior Probability): the posterior probability of the key;

[0031] DTW (Dynamic Time Warping): dynamic time warping;

[0032] CNN (Convolutional Neural Network): convolutional neural network.

[0033] see figure 1 , in one embodiment, provide a kind of piano performance scoring method, comprise the steps:

[0034] S120, extracting musical features of the performance audio, and normalizing it;

[0035] S140, usin...

Abstract

The invention discloses a piano playing scoring system and method thereof. The method comprises following steps of extracting music characteristics of a played audio and carrying out normalization processing on the music characteristics; using the music characteristics subjected to the normalization processing as input of a neural network mathematical model, and acquiring key posterior probabilitycharacteristic sequences of the played audio; carrying out template matching processing on the key posterior probability characteristic sequences of the played audio and a key posterior probability characteristic sequences of a template audio to acquire multiple music characteristics for describing the matching degree so as to judge the played audio; and inputting the music characteristics for describing the matching degree into a piano playing scoring model so as to obtain scoring results. According to the invention, subjective factor deviations caused by personal difference of scorers in atraditional scoring method are avoided; the real level of players is truly reflected; and necessary scores can be provided for autonomous practices of piano learners.

Description

technical field [0001] The invention relates to the technical field of speech processing, in particular to a piano performance scoring method, device, computer equipment and storage medium. Background technique [0002] In recent years, with the improvement of material living standards, people have put forward higher requirements for the quality of spiritual life, and more and more people choose to learn piano. [0003] However, the traditional evaluation of piano performance level is carried out by manual scoring, especially the on-site assessment of piano performance. After the live piano performance is completed, use the form of a table to split the performance content of the test repertoire into specific detailed requirements, and each rater will score according to the performance level of the performer. [0004] Although in order to get rid of the personal color of subjective likes and dislikes of raters, the final score is calculated by adding the scores of all raters...
