Description
Technical Field
The embodiment of the invention relates to the technical field of audio signal processing, in particular to a intonation assessment method, a intonation assessment device, intonation assessment equipment and a storage medium.
Background
With the development of artificial intelligence technology, it becomes a need and possibility to use artificial intelligence technology to assist in accompanying the learners of musical instruments. For the learner of the musical instrument, an important link for performing the auxiliary training is to see whether the pitch of the performance is accurate. Since the pitch can be obtained by fundamental frequency extraction, as long as there is a reference answer, i.e., fundamental frequency or pitch (semitone) information corresponding to each note of the played music, the result of judging whether the music is accurate can be obtained by extracting the pitch played by the musical instrument and comparing the extracted pitch.
However, there is a biggest problem in directly using the pitch (semitone) to judge whether the pitch of the musical instrument is consistent with the reference answer (pitch obtained by the standard demonstration performance) in that: unless the instrument used by the player is tuned to the reference answers demonstrating that the instrument used for the performance is at a pitch, direct comparison of the absolute value of the pitch is not an objective intonation estimate. This is because the absolute pitch is the absolute value of the frequency, but the melody is a problem of whether or not the scale difference between the pitch and the chord is harmonious. The same melody can be played on the basis of different "keys", and the keys of the same instrument may not be on one frequency, such as guitar, violin, etc., unless one calibrates according to the standard requirements, but it is difficult to work on the same key only by calibrating the relative pitch, and naturally the absolute pitch cannot be used for comparison. Therefore, the existing intonation assessment methods are not accurate enough.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a intonation assessment method according to an embodiment of the present invention. The present embodiment is applicable to a case where the pitch of a musical tone is assessed on time. The method may be performed by a intonation evaluation device, which may be implemented in software and/or hardware, for example, which may be configured in a computer device. As shown in fig. 1, the method includes:
s110, obtaining the current musical tone information to be evaluated and the auxiliary musical tone information to be evaluated in the musical tone information to be evaluated.
In the present embodiment, the musical tone information can be understood as sound information that the user utters through the musical instrument. The musical instruments played by the user include, but are not limited to: wind instruments, pluck instruments, keyboard instruments, percussion instruments, and the like. Wherein, the wind instruments such as Sheng, Lusheng, gang Sheng, cucurbit flute, pipe, Bawu, Xun, suona, vertical bamboo flute, etc.; plucked musical instruments such as pipa, zither, dulcimer, seven-string instrument (guqin), thermosyphon, dongbula, ruan, liuqin, tricing, yueqin, bobble, etc.; keyboard musical instruments such as pianos, organs, accordion, electronic organ, etc.; percussion instruments such as a drum (bass drum), a bang bell, a cylinder drum, a timpani cylinder drum, a bronze drum, a gong and a pongo, a snare drum, a rowed drum, a darbo (tambourine), a cymbal, etc.
Optionally, the musical tone information to be evaluated may be obtained in real time through the recording device, or may be complete musical tone information uploaded by the user, which is not limited herein.
In one embodiment of the present invention, acquiring the current tone information to be evaluated and the auxiliary tone information to be evaluated from among the tone information to be evaluated, includes: the tone information to be evaluated at present among the tones to be evaluated is taken as the current tone information to be evaluated, and the last tone information of the current tone information to be evaluated is taken as the auxiliary tone information to be evaluated.
When the musical tone information to be evaluated is the musical tone information recorded in real time, the current musical tone information to be evaluated may be the musical tone information recorded at the present time, and the auxiliary musical tone information to be evaluated may be the musical tone information recorded at the last time. If the currently recorded musical tone information is the first musical tone information, it may not be evaluated first, and after recording the musical tone information of the next time, the musical tone information of two times is integrated for evaluation, and the evaluation result of the musical tone information of the next time is taken as the evaluation result of the musical tone information of the first time.
When the musical tone information to be evaluated is complete musical tone information uploaded by a user, sequentially evaluating musical tones in the musical tone information to be evaluated once according to the musical tone sequence, taking the current musical tone information to be evaluated as the current musical tone information to be evaluated, and taking the musical tone information at the previous moment of the current musical tone information to be evaluated as auxiliary musical tone information to be evaluated; similar to the tone information recorded in real time, if the current tone information to be evaluated is the first tone information, the tone information at the next time can be directly acquired without evaluating the first tone information, the tone information at the two times is integrated for evaluation, and the evaluation result of the tone information at the next time is used as the evaluation result of the tone information at the first time.
And S120, determining a tone accuracy evaluation parameter according to the current musical tone information to be evaluated and the auxiliary musical tone information to be evaluated.
Considering that the same melody can be played based on different "keys" and the keys of different instruments may not be at one frequency, it is difficult to ensure that they are at the same key only by relative pitch calibration, resulting in a problem of low accuracy of intonation assessment. In this embodiment, the current tone information to be evaluated is not directly compared with the standard current tone information, but is evaluated in combination with the auxiliary tone information to be evaluated on the basis of the current tone information to be evaluated.
It is understood that the melody is the manifestation of whether the pitch differences between notes are harmonious, C (duo) d (re) e (mi) f (fa) g (so) a (ra) b (ti) is an octave, if C is not specified? It is actually a sensation obtained from a relative comparison of the sound differences. Therefore, it is possible to determine whether the melody tone level of the tone information to be evaluated is accurate, as long as the tone level evaluation parameter is characterized by the relative value between adjacent tones.
In one embodiment, the determining of the intonation evaluation parameter based on the current tone information to be evaluated and the auxiliary tone information to be evaluated includes: determining a current tone frequency of the current tone information to be evaluated; determining an auxiliary tone frequency of the auxiliary tone information to be evaluated; a intonation evaluation parameter is determined based on the current tone frequency and the auxiliary tone frequency. To simplify the intonation evaluation operation, the intonation evaluation parameter is preferably in numerical form, and the numerical representation of the tone information may be a tone frequency, so that the intonation evaluation parameter can be determined based on the tone frequencies of adjacent tone information. Specifically, a current tone frequency is determined based on the current tone information to be evaluated, an auxiliary tone frequency is determined based on the auxiliary tone information to be evaluated, and a intonation evaluation parameter is determined based on the current tone frequency and the auxiliary tone frequency. Alternatively, the characteristic values of the current tone frequency and the auxiliary tone frequency may be calculated as the intonation evaluation parameters, such as the difference between the current tone frequency and the auxiliary tone frequency as the intonation evaluation parameter, or the ratio of the current tone frequency and the auxiliary tone frequency as the intonation evaluation parameter, or the like. It should be noted that the determination method of the intonation evaluation parameter is not limited herein, but the determination method needs to be consistent with the determination method of the standard intonation parameter. If the difference between the standard current tone frequency and the standard auxiliary tone frequency is used as the intonation marking parameter when determining the intonation marking parameter, the difference between the current tone frequency to be evaluated and the auxiliary tone frequency to be evaluated is required to be used as the intonation evaluation parameter when determining the intonation evaluation parameter.
Optionally, determining the current musical tone frequency of the current musical tone information to be evaluated includes: and extracting the current fundamental frequency information of the current musical tone information to be evaluated, and converting the current fundamental frequency information into the current absolute semitone pitch to obtain the current musical tone frequency. Specifically, the fundamental frequency of the current tone information to be evaluated is extracted to obtain the current fundamental frequency information, then the current fundamental frequency information is converted into the absolute semitone pitch according to the music theory knowledge, and the sum of all absolute semitone pitches at the current moment is used as the current absolute semitone pitch. For example, assuming that C is C3 and C3 is 130.81Hz) of the player, the played melody first extracts a fundamental frequency to obtain fundamental frequency information; then, according to the music theory knowledge, the fundamental frequency is converted into the absolute half pitch: p (i) ═ 69+12 × log2(f (i)/440). Wherein f (i) is the fundamental frequency corresponding to the time i, p (i) is the absolute semitone height, and the same time points of p (i) are combined to obtain the absolute semitone pitch in the period.
Alternatively, the determining of the auxiliary tone frequency of the auxiliary tone information to be evaluated includes: and extracting auxiliary fundamental frequency information of the auxiliary musical tone information to be evaluated, and converting the auxiliary fundamental frequency information into auxiliary semitone pitch to obtain the auxiliary musical tone frequency. It will be appreciated that the auxiliary tone frequency is determined in a similar manner to the determination of the current tone frequency, i.e. the fundamental frequency is extracted first, and the fundamental frequency is converted to the most halved pitch based on the musical theory knowledge, resulting in the auxiliary most halved pitch, i.e. the auxiliary tone frequency. For details, reference may be made to the above embodiments, which are not described herein again.
On the basis of the above-described arrangement, determining the intonation evaluation parameter based on the current tone frequency and the auxiliary tone frequency includes: a relative semitone difference between the current tone frequency and the auxiliary tone frequency is determined, and the relative semitone difference is used as a intonation evaluation parameter. After the current tone frequency and the auxiliary tone frequency are determined, the difference between the current tone frequency and the auxiliary tone frequency, i.e., the relative semitone difference, can be directly used as the intonation evaluation parameter. The difference value is directly used as the calculation complexity of the intonation evaluation parameter simplified by the intonation evaluation parameter, so that the accuracy of the intonation evaluation parameter is ensured.
And S130, evaluating the accuracy of the current musical tone information to be evaluated based on the accuracy evaluation parameter.
In this embodiment, the accuracy rating parameter may be compared with the accuracy standard parameter to obtain the accuracy of the current musical tone information. And synthesizing the accuracy of all the musical tone information in the musical tone information to be evaluated to obtain the integral accuracy of the musical tone information to be evaluated.
In one embodiment, assessing the intonation of the current musical tone information to be assessed based on the intonation assessment parameter includes: and comparing the half tone difference with the standard half tone difference, and obtaining the accuracy of the musical tone information to be evaluated according to the comparison result. When the relative semitone difference between the current tone frequency and the auxiliary tone frequency is directly used as the intonation evaluation parameter, the relative semitone difference may be directly compared with the standard semitone difference, and the intonation of the current tone information may be determined based on the comparison result.
The embodiment of the invention acquires the current musical tone information to be evaluated and the auxiliary musical tone information to be evaluated in the musical tone information to be evaluated; determining a tone accuracy evaluation parameter according to the current tone information to be evaluated and the auxiliary tone information to be evaluated; the accuracy of the current musical tone information to be evaluated is evaluated based on the intonation evaluation parameters, and the intonation of the current musical tone information to be evaluated is judged in an auxiliary mode through the auxiliary musical tone information to be evaluated, so that the inaccuracy of direct judgment according to the current musical tone information when the musical instrument pitch is different is avoided, and the accuracy of the intonation evaluation is improved.
Example two
The present embodiment provides a preferred embodiment based on the above-described embodiments.
According to music theory, C (duo) D (re) E (mi) F (fa) G (so) A (ra) B (ti) is an octave, two semitone differences are between C and D, two semitone differences are between D and E, one semitone difference is between E and F, F and G, two semitone differences are between G and A, A and B, and one semitone difference is between B and C of the next octave, as shown in Table 1:
TABLE 1
| Musical interval | Half tone difference (note number) |
| Between C and D | 2notes |
| Between D and E | 2notes |
| Between E and F | 1note |
| Between F and G | 2notes |
| Between G and A | 2notes |
| Between A and B | 2notes |
| Between B and the next octave C | 1note |
Then, as long as the reference melody is re-characterized by the note difference between adjacent notes, it can be judged whether the played intonation is correct by examining whether the note difference between adjacent notes of the played melody matches the reference note difference.
The tone level evaluation method provided by the embodiment of the invention comprises the following steps:
1) the absolute pitch of the standard tone is converted into a semitone difference. For example, if the standard tone performs a string of notes C-C4 standard middle C and the standard tone performs a string of notes C4C 4D 4E 4F 4G 4 a 4B 4C 5, the standard half-tone difference after conversion is as in table 2.
TABLE 2
2) Recording a melody played by a player through a musical instrument (assuming that the player has C3 and C3 130.81Hz), and extracting a fundamental frequency to obtain fundamental frequency information;
3) then, according to the music theory knowledge, the fundamental frequency is converted into the absolute half pitch:
p (i) + 69+12 × log2(f (i)/440), where f (i) is the fundamental frequency corresponding to the time i, p (i) obtains the half pitch, and p (i) is combined at the same time point, so as to obtain the half pitch in the period of time;
4) the relative semitone difference of the performance result of the player is obtained by p (j) -p (j-1), and the relative semitone difference is compared with the standard semitone difference, so that whether the musical tones have deviation or not can be known.
According to the technical scheme provided by the embodiment of the invention, when the intonation of the player is evaluated, the musical instrument key of the player is not required to be consistent with the reference musical instrument, and the applicability of performance evaluation is improved.
