Relaxation to one-dimensional postglottal flow in a vocal fold model
We propose a vocal fold model in which postglottal flow is not 1D in the vicinity of the glottis. A relaxation length for the flow is incorporated into the model as a parameter. Vocal fold behavior is affected by the relaxation length through delayed feedback. Lowering relaxation distances introduces complexity in the response of the system.
