Abstract
Purpose: Fundamental Frequency (F0
) in emotional and neutral
speech in Brazilian Portuguese was analyzed. Methods: Three professional
actresses participated in the survey reading a text in two conditions: neutral
speech and acted emotion speech. Four emotions were taken into account
for this study: joy, anger, fear and sadness. For each situation, actresses repeated
five times, totaling 75 recordings. Speech sample recording took place in the
Multimedia Lab Studio Electronic Computing Center of the University of
São Paulo (USP-CCE) through specific equipment. A sentence was selected
to be segmented and analyzed in smaller units (syllables). In order to obtain
F0 values, the software PRAAT and some of its scripts were used. Results:
Analyzing F0 average
of each emotion, we found that joy shows higher
frequency bands than sadness that has very low values of F0
. Variation of F0
in anger remained similar among the actresses speech. On the other hand, fear
did not offer any F0
range pattern. Conclusion: F0
values , both mean and
variation, show to be important in the differentiation of emotions: joy, anger
and sadness. Fear seems to suffer other acoustic and physiological influences
– a those could be analyzed in a more broad study – other than F
