Predicted Maximum Phonation Time. It is possible to estimate or predict a patients MPT (in seconds) by using the formula VC/110 X 0.67 for males and VC/100 X 0.59 for females. Use this measure to compare actual MPT to the predicted value.his is an aerodynamic assessment of vocal function that allows the estimation of mean flow rate using hand-held spirometers (dry spirometers) to measure vital capacity and a regression equation determined by Rau and Beckett (1993). The first step is to determine vital capacity and maximum phonation time.
