dc.description.abstractRecently, focus of research in the field of affective computing was shifted to spontaneous interactions and time-continuous annotations. Such data enlarge the possibility for real-world emotion recognition in the wild, but also introduce new challenges. Affective computing is a research area, where data collection is not a trivial and cheap task; therefore it would be rational to use all the data available. However, due to the subjective nature of emotions, differences in cultural and linguistic features as well as environmental conditions, combining affective speech data is not a straightforward process. In this paper, we analyze difficulties of automatic emotion recognition in time-continuous, dimensional scenario using data from RECOLA, SEMAINE and CreativeIT databases. We propose to employ a simple but effective strategy called “mixup” to overcome the gap in feature-target and target-target covariance structures across corpora. We showcase the performance of our system in three different cross-corpus experimental setups: single-corpus training, two-corpora training and training on augmented (mixed up) data. Findings show that the prediction behavior of trained models heavily depends on the covariance structure of the training corpus, and mixup is very effective in improving cross-corpus acoustic emotion recognition performance of context dependent LSTM models. © 2018, Springer Nature Switzerland AG.
