Popis: International audience; The physics of voice has been fruitful in producing a wide variety of models, from full-featured numerical ones (mostly based on FEM for tissues and FVM for airflow) to reduced-order models focusing on the predominant phenomenon. A large body of work in the second category relies on the description of the glottal aerodynamics from the late 1950, based on Bernoulli theorem, thus ignoring rapid or large-amplitude motions of the vocal folds. This is justified on experiments in rigid static larynx-like ducts. However, those simplified models contain an intrinsic paradox where the tissues are driven by the power received by the flow, whose description assumes it does not provide power to tissues. The main objective of the current communication is to propose a minimal model of the full vocal apparatus that restores a consistent description of the power exchange between the glottal airflow and the vocal folds.
