Analisamos o efeito do sexo, do estilo de elocução e da língua (alemão, estoniano, francês, inglês, italiano, português e sueco) sobre estimadores de tendência central e dispersão da frequência fundamental da fala. Os estilos são entrevista, leitura de frases e de palavras. As línguas diferem entre si em termos do valor típico de F0 usado por seus falantes. O estilo leitura de frases apresenta valores maiores do que a entrevista, mas o efeito não é uniforme entre as línguas. Diferenças significativas entre o estilo leitura de palavras e entrevista são mais raros. Todos os estimadores de tendência central estudados sofreram efeitos dos três fatores testados. Os homens apresentaram variabilidade de F0 ligeiramente maior do que as mulheres de forma significativa em três de cinco estimadores. O estilo entrevista tem maior variabilidade em dois. As línguas não diferem em termos de variabilidade de F0.

Effect of language, speaking style and speaker sex on global measures of fundamental frequency
We analyze the effect of speaker sex, speaking style and language (English, Estonian, French, German, Italian, Portuguese, Swedish) on global statistical measures of the voice fundamental frequency. The styles studied are interview, sentence reading and word list reading. Typical F0 values used by speakers among languages differ both in male and female speakers. Sentence reading has slightly higher values than interview, but the effect is not uniform among languages. In few cases word reading and interview values differ significantly. All central tendency estimators are affected by the variables tested. Three out of five estimators of dispersion show slightly higher values for male than for female speakers. Among styles, the interview has higher standard deviation and coefficient of variation. Languages do not differ among themselves in terms of F0 variability.
