Article Synopsis
- The paper investigates how vocal folds and the vocal tract interact at the beginning of sound production, focusing on how this interaction is affected by changes in vocal tract length.
- Data from a mechanical model indicate that slight changes in the vocal tract length can lead to significant shifts in the pressure and frequency needed for sound oscillation.
- A mathematical model is presented to explain these frequency shifts, revealing that they are caused by specific types of structural changes called saddle-node bifurcations, which can lead to sudden jumps in frequency based on the level of acoustic coupling and subglottal pressure.
