Statistical characteristics of the formants of the Romanian vowels in emotional states

We investigate the influence of the emotions expressed by female and male speakers on the formants of the vowels in the Romanian language. The main conclusions are that the formant F4 is not significantly modified by the expressed emotion; the pitch is significantly increased for joy in all vowels; the pitch is slightly decreased under sadness, and that the change in statistic distribution is quite large in all cases (vowels and states).
