Instrument analysis of the power supply for voice pulmonary air. Aerodynamic analysis of voice can include spirometry, which assesses various capacities and capabilities of the respiratory system, apart from phonation. It also allows determination of the pressure and flow through the vocal folds during phonation.

Our clinicians believe that aerodynamic analysis of voice has yet to earn a place as part of the routine diagnostic workup (see the integrative diagnostic model). Aerodynamic analysis of voice, however, may be of interest for voice research, and when the equipment is used as a biofeedback tool in the therapy room.
