Approach Model of Speech Production Using Helmholtz Resonator and Wave Equation

The vocal cords are used to produce sounds, these sounds are called voice. The vocal tract acts as a cavity resonator with forming regions where the sounds produced are filtered. According to the constitution of the respiratory human apparatus, the larynx and the vocal cords and, our voice have a personal and unique timbre. In this paper the vocal tract is modeled using Helmholtz resonator that is excited by a source (the vocal cords) that is represented by vibrating strings using the wave equation, lumped element modeling is used to describe the Helmholtz resonators in an equivalent circuit model, and finally we will obtain the transfer equation of the model of voice production.
