The Discriminant Functional Analysis was done used 100 calls (20 per male) as a training sample and 100 other calls as a test sample. Definition of the acoustic variables correlated with functions 1 and 2: duration of the call (Dt), number of harmonics (H), fundamental frequency at the beginning (F0beg), end (F0end) and top (F0max) of the call.
