Embodiment 1

[0024] figure 1 It is a flow chart of a pitch assessment method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of assessing the intonation of musical tones. The method can be executed by an apparatus for evaluating pitch, and the apparatus for evaluating pitch can be implemented in the form of software and / or hardware, for example, the apparatus for evaluating pitch can be configured in a computer device. Such as figure 1 As shown, the method includes:

[0025] S110. Obtain the current tone information to be assessed and the auxiliary tone information to be assessed in the tone information to be assessed.

[0026] In this embodiment, the tone information can be understood as sound information issued by the user by playing a musical instrument. Wherein, the musical instruments played by the user include but are not limited to: wind instruments, plucked string instruments, keyboard instruments, percussion instruments and the...

Embodiment 2

[0043] This embodiment provides a preferred embodiment on the basis of the foregoing embodiments.

[0044] According to music theory knowledge, C(duo)D(re)E(mi)F(fa)G(so)A(ra)B(ti) is an octave range, and there is a difference of two semitones between C and D , there is a difference of two semitones between D and E, one semitone between E and F, two semitones between F and G, G and A, A and B, and B and C in the next octave There is a semitone difference between them, as shown in Table 1:

[0045] Table 1

[0046] interval Semitone difference (number of notes) Between C and D 2notes Between D and E 2notes Between E and F 1 note Between F and G 2notes Between G and A 2notes Between A and B 2notes Between B and the next octave C 1 note

[0047] Then as long as the note difference between adjacent notes is used to re-characterize the reference melody, it can be judged whether the pitch of the performance is accura...

Embodiment 3

[0059] figure 2 It is a structural schematic diagram of an intonation evaluation device provided by Embodiment 3 of the present invention. The pitch assessment device can be implemented in the form of software and / or hardware, for example, the pitch assessment device can be configured in computer equipment. Such as figure 2 As shown, the device includes a musical tone information acquisition module 210, an evaluation parameter determination module 220 and a musical tone intonation evaluation determination module 230, wherein:

[0060] The tone information acquisition module 210 is used to acquire the current tone information to be assessed and the auxiliary tone information to be assessed in the tone information to be assessed;

[0061] An evaluation parameter determination module 220, configured to determine pitch evaluation parameters according to the current musical tone information to be evaluated and the auxiliary musical tone information to be evaluated;

[0062] Th...

Abstract

The embodiment of the invention discloses an intonation evaluation method and device, equipment and a storage medium. The intonation evaluation method comprises the steps of obtaining to-be-evaluated current musical sound information and to-be-evaluated auxiliary musical sound information in to-be-evaluated musical sound information; determining intonation evaluation parameters according to the to-be-evaluated current musical sound information and the to-be-evaluated auxiliary musical sound information; and evaluating the intonation degree of the to-be-evaluated current musical sound information based on the intonation evaluation parameters. According to the method provided by the embodiment of the invention, the intonation degree of the to-be-evaluated current musical sound information is judged in an auxiliary manner through the to-be-evaluated auxiliary musical sound information, so that the inaccuracy of judging directly according to the current musical sound information when the musical instrument tones are different is avoided, and the accuracy of intonation evaluation is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of audio signal processing, and in particular, to a pitch evaluation method, device, equipment and storage medium. Background technique [0002] With the development of artificial intelligence technology, it has become a demand and possibility to use artificial intelligence technology to assist musical instrument learners. For musical instrument learners, an important part of auxiliary practice is to check whether the pitch of the performance is accurate. Since the pitch can be obtained by extracting the fundamental frequency, as long as there is a reference answer, that is, the fundamental frequency or pitch (semitone) information corresponding to each note of the performance track, it can be compared by extracting the pitch played by the instrument, and Get the result of judging whether it is accurate. [0003] However, there is a biggest problem in directly using the pitch (sem...
