Here, we review past efforts and identify important conceptual and methodological challenges ( Scherer, 1986 Gobl, 2003 Patel et al., 2011). Specifically, it remains uncertain how different vocal cues such as fundamental frequency and timbre are processed in the listener’s brain to inform emotional inferences ( Frühholz et al., 2016 Frühholz and Schweinberger, 2021). Yet, after over 30 years of research, and in some contrast to the accuracy with which listeners infer vocal emotions, the identification of emotion-specific acoustic profiles has been only partially successful ( Banse and Scherer, 1996 Juslin and Laukka, 2003 Brück et al., 2011). It is well established that listeners readily infer a speaker’s emotional state based on the speaker’s voice acoustics ( Banse and Scherer, 1996 Juslin and Laukka, 2003). Vocal emotion perception, timbre, fundamental frequency (F0), parameter-specific voice morphing, event-related potentials (ERPs) Introduction Together, these findings offer original insights into the relative significance of different acoustic parameters for early neuronal representations of speaker emotion and show that such representations are predictive of subsequent evaluative judgments. ERPs (P200 and N400) and behavioral data converged in showing that both F0 and timbre support emotion processing but do so differently for different emotions: Whereas F0 was most relevant for responses to happy, fearful and sad voices, timbre was most relevant for responses to voices expressing pleasure. We used these stimuli together with fully modulated vocal stimuli in an event-related potential (ERP) study in which participants listened to and identified stimulus emotion. Here we pursued this issue using a novel parameter-specific voice morphing technique to create stimuli with emotion modulations in only F0 or only timbre. Yet, how these parameters are processed and integrated to inform emotion perception remains largely unknown. Our ability to infer a speaker’s emotional state depends on the processing of acoustic parameters such as fundamental frequency (F0) and timbre.
