ABSTRACT
The present work studies spontaneous emotional speech in European Portuguese, comparing thevalues obtained in measuring acoustic parameters in this study with the ones known for otherlanguages and for simulated. The spontaneous expression of emotions recorded in the street or fromtelevision programs may bring very relevant results, but even in those situations it is difficult todetermine the individual’s true emotion (it is often only possible to be identify through the context)(Patrick, 2008). The main focus of our study is on voice related parameters such as F0, jitter, shimmerand HNR that will be liable to compare with previous studies of emotions produced by an actor. Usingthe Feeltrace system it is possible to better describe the sensation caused by the stimuli (in any of theemotions in question) and describe in more dynamic manner the emotion. We also realize that,although the emotions produced by actors show some differences, because they are necessarilyexaggerated, the parameter values are all very similar, valuing the studies that are usually obtainedbased on utterances produced by performers. Given the scarcity of studies on voice quality inEuropean Portuguese, it is important to highlight that this work presents an original corpusspecifically created for this study. We recognize the limitations of the presented research seeing theresults as first approaches that must be deeply studied being important to areas such as robotics andhealth technology.
