Abstract | In an interaction, it is well known that information is being exchanged which is meaningful beyond the pure context. Especially, intentional and emotional characteristics are essential to improve not only the relationship in a human-human interaction, but also to provide benefits to increase the understanding of the transmitted information. For technical systems it is favourable to detect and interpret these additional characteristics and to transfer appropriate knowledge to human-machine interactions. In particular, this enables an automatic recognition of emotions. In this paper, we focus on speech as the transmitting modality. Beyond the detection of the location and nature of emotional instances, automatic interpretation asks "if", "how", and "when" emotions change in an interaction. In the EmoGest corpus, providing human-human interactions with emotionally induced subjects, we analyse the subject's emotional evolution. For this, we investigate the utterances spoken at the beginning and at the end of particular sessions. Automatic emotion recognition from speech shows that in intra- and inter-individual evaluations, significant differences (at least p<0.05) in the emotional state train of the subjects can be detected. Intra-individual experiments indicate a trend towards less affective states in subsequent interactions if no further inducement is given. In addition, the inter-individual analyses show that a kind of alignment can be seen in the emotional state trains of the single subjects even if their sessions were strictly separated. |
