Can you hear what I feel? A validated prosodic set of angry, happy, and neutral Italian pseudowords

This contribution aims to establish a set of validated vocal Italian pseudowords that convey three emotional tones (angry, happy, and neutral) for prosodic emotional processing research. We elaborated the materials by following a series of specific steps. First, we tested the valence of a set of written pseudowords generated by specific software. Two Italian actors (male and female) then recorded the resulting subset of linguistically legal and neutral pseudowords in three emotional tones. Finally, on the basis of the results of independent ratings of emotional intensity, we selected a set of 30 audio stimuli expressed in each of the three different emotions. Acoustic analyses indicated that the prosodic indexes of fundamental frequency, vocal intensity, and speech rate anchored individual perceptions of the emotions expressed. Finally, the acoustic profile of the set of emotional stimuli confirmed previous findings. The happy tone stimuli showed high f 0 values, high intensity, high pitch variability, and a faster speech rate. The angry tone stimuli were also characterized by high f 0 and intensity, but by relatively smaller pitch variability and a lower speech rate. This last profile echoes the description of “cold anger.” This new set of prosodic emotion stimuli will constitute a useful resource for future research that requires emotional prosody materials. It could be used both for Italian and for cross-language studies.
