A New Approach on Solving One-Mass Model of Vocal Cord using Hybrid Cubic B-Spline Collocation Method

Abstract

The vocal cords, also known as vocal folds, are responsible for producing sound and creating the voice. In this work, hybrid cubic B-spline collocation method (HCBs) and ode45 built-in solver in MATLAB were applied to solve one-mass model of vocal cord numerically. From the model, displacements were generated by analysing the voice recording samples of 109 healthy participants. Based on the recordings, the frequency of each sample was accumulated and utilized in displacements calculation. In order to verify the value of displacements, absolute error and maximum error were calculated. The numerical results were indicated that HCBs generate closer displacement with ode45. The error was shown that HCBs could be reliable method and produce accurate displacement of one-mass model of vocal cord.
