Frequency jumps are a common phenomenon in voice production. They are perceived as discontinuities in voice pitch caused by smooth changes of physiological parameters, and may be observed in transitions between chest and falsetto vocal registers. Here, a recent model of birdsong production is used to model an oscillator source for the vocal folds coupled to an acoustic waveguide for the vocal tract, in terms of a delay differential equation. Numerical integration of the equation shows regions… CONTINUE READING
