Document Summary
The vocal tract is an open-ended, bent tube that contains air. can be classified as a wave resonator. Within this anatomical tube, the pharynx, oral cavity, and nasal cavity exists. Each of these structures has its own rg and all together produce an overall rf. In this capacity, each structure acts as a band-pass filter. A band-pass filter is a resonator that filters out both high and low frequencies. As a resonator, the vocal tract is irregularly shaped but broadly tuned with a large bandwidth. In addition, it is a variable resonator meaning that the rfs of the vocal tract change depending on its shape. In other words, the vocal tract constrictions and cross-sectional areas that we use during articulation impact the rfs that are produced. Sound waves are produced by the vocal folds that passes through the vocal tract freely creating additional frequencies. The term formant simply refers to the resonant qualities of the vocal tract.
