Problems solved by technology

These subjective feelings vary from person to person and are difficult to quantify. Therefore, it is impossible to make an objective and accurate judgment on whether the resonance is good or bad, and it is also impossible to resonate and beautify the singer's voice to make the sound more beautiful.

Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] Sound is produced by vibration, and it is almost impossible for an object to vibrate back and forth according to a certain period of vibration. That is to say, when the sounding object makes a sound, it will produce many sub-vibrations, thus generating many waves (harmonic waves) of different frequencies. Because the phase difference of these many waves of different frequencies is very small (that is, the time interval is very short), people cannot distinguish them separately, so these waves will be mixed together to give people an overall feeling, and this feeling forms the timbre. The frequency with the largest relative amount in a sound determines the pitch of the sound, while the relative amount distribution of other frequencies determines the timbre. People distinguish different vocal objects not by the frequency of the sound, the frequency only determines the t...

Abstract

The present invention proposes a method for beautifying the sound, comprising the steps of: obtaining the voice signal of the singer and performing pre-emphasis on the voice signal, frame-by-frame windowing to divide the voice signal into short time frames; estimating the voice signal of each frame The pitch frequency f0 and the first formant frequency f1, make the ratio f1 / f0; and calculate the average value of the signal ratio f1 / f0 of each frame in the singer's current sentence; set it to judge the resonance degree between the singer's voice and the original sound threshold, and compare the average value with the threshold; if the average value is greater than the threshold, it is considered that the resonance is poor; when a resonance difference is detected, the frequency band at the first formant position is weakened, And / or enhance the frequency band at the pitch frequency position to increase resonance and beautify the voice, making singing easier, and can sing beautiful singing without professional training, improving the entertainment of singing.

Description

technical field [0001] The invention relates to the technical field of intelligent voice, in particular to a method and device for beautifying voice. Background technique [0002] Timbre refers to the aurally produced property of a sound by which a listener can judge the difference between two sounds presented in the same manner with the same pitch and loudness. Therefore, the vocal timbre during singing refers to the voice characteristics that people use to identify the specific singer when different singers sing the same song. [0003] The quality of resonance is an important indicator to measure the singer's timbre. If the voice lacks resonance in singing, the voice will often appear weak and lack color. And good sound resonance is of great help to the expansion of volume, the improvement of timbre and the spread of sound. However, the current description of resonance is mostly based on subjective feelings, for example, whether the sound is penetrating, whether the col...
