| Abstract | This research is a first description of voice and emotion for European Portuguese. Based on studies for several languages (Finish, English, German), we studied voice related parameters varying according to the emotion expressed. The analysed parameters are related to F0, jitter, shimmer and Harmonic Noise Ratio (HNR). This is an all-embracing study that approaches voice and its relation/variation according to emotion. Three sources are considered: psychogenic voice pathology; emotion produced by actors; and spontaneous emotion analyses. Being a trailblazing research in this area, values were measured for all three types of production. We highlight the fact that our work only considers voice analysis without considering facial expression and body posture. In order to make comparative studies with the data collected for each corpus (pathology, acted emotion and spontaneous emotion), we used the same analysis methods (Praat, SFS, SPSS, and Hoarseness Diagram - for pathological voice analysis; and Feeltrace system - for the spontaneous emotions). Studies and analyses related to acted emotion are complemented by perceptual tests with American English and European Portuguese speakers. Theses tests, as well as spontaneous emotion analysis, allowed the extraction of data for Portuguese. Both emotion expression and perception have many universal characteristics. However, Portuguese language proved to have some particularities. Values obtained for neutral expression, sadness, and joy are very close, contrary to what happens in other languages. Moreover, these three emotions (from distinct families) are those that present the most difficulty (to both informant groups) in the distinction perceptual tests. This is probably the main particularity in emotion expression as far as Portuguese is concerned, maybe due to cultural factors. This research also shows that acted emotion is close to spontaneous emotion expression. However, some parameters present different values, because the actor tends to somewhat exaggerate the emotion. This work led to the creation of original corpora that can be an important resource for future analyses in an area still in deficit in terms of scientific research in Portugal. Both corpora and the obtained results may be useful in areas such as Speech Science, Robotics, and Education. |
