Abstract

A large sample of vowels produced by male and female speakers were inverse filtered and parameterized using 21 different glottal flow parameters. The performance of the different parameters in expression of the phonation type was then tested using objective statistical methods. The comparison of the results revealed marked differences in the parameters ’ performance, and therefore, guidelines for parameter use and comparison were established.
