Singing tone quality detection device with closed characteristic

Abstract

The invention discloses a singing tone quality detection device with closed characteristics. The singing tone quality detection device comprises a laryngoscope, a light source, a computer and a high-speed glottis video camera system. Through the laryngoscope and the high-speed glottis video camera system, images of vocal cords are acquired. The image information is transmitted to the computer. Thecomputer performs data analysis on the image information and the vibration rule by utilizing vocal cord vibration processing system software of a two-mass block-finite element model. Vocal cord vibration waveforms and vibration parameters in the images are extracted. The operation state of the vocal cord when the vocal cord makes different sounds and the vibration regularity when the vocal cord makes sounds can be visually understood. The defects existing in singing practice can be found through image automatic analysis of vocal cord vibration processing system software of a two-mass-block-finite-element model and the nonlinear analysis function of continuous waveforms, improvement is conducted, and the vocal cord training effect is improved. The method has the characteristics of real-time performance and effectiveness of singing tone quality practice detection, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a detection device for singing timbre with closed characteristics. Background technique [0002] The vocal cords, also known as the sound wall, are an important part of the human body's vocal production. It is located in the middle of the throat and consists of vocal cord muscles, vocal cord ligament, and mucous membrane. The left and right sides are symmetrical to each other. Vocal cord closure is a term commonly used in vocal music. When vocalizing, the vocal cord muscles will exert force to tighten the vocal cords. It will become very small. When the breath passes through this small space, the two white sound walls vibrate continuously, forming sound. In the process of vocal music training, people's tone of voice can be improved by training vocal cord closure, but when performing vocal cord closure training, people do not have a thorough understanding of the operati...

AI Technical Summary

Problems solved by technology

In the process of vocal music training, people's tone of voice can be improved by training vocal cord closure, but when performing vocal cord closure training, people do not have a thorough understanding of the operation of their vocal cords, and cannot intuitively understand when the vocal cords make a specific sound. , the shape maintained by the vocal cords, the memory of vocal cord closure training is not deep enough to understand the main points of training, thus reducing the effect of training

In addition, only considering the physiological structure of vocal fold closure cannot completely solve the auditory problem of timbre closure. If the characteristics of timbre closure can be satisfied through systematic singing vocal training, we believe that physiological vocal fold closure has been completed.
