Normative Speaking Fundamental Frequency (SFF) characteristics of Brazilian male subjects

M I Pegoraro-Krook et al. Braz J Med Biol Res. 1994 Jul.

Abstract

The present study was carried out in order to obtain normative Speaking Fundamental Frequency (SFF) data for 150 Brazilian Portuguese-speaking male subjects (mean age, 19.4; range, 17-30) in two different vocal tasks, i.e., oral reading and counting. Mean (+/- SD) SFF was 134.9 +/- 17.9 Hz for oral reading and 130.5 +/- 18.5 Hz for counting. The mean SFF values obtained in this investigation were similar to data reported in previous studies.
