| Abstract: | This study presents a scheme for multilingual speech emotion recognition. Determining the emotion of speech in general relies upon specific training data, and a different target speaker or language may present significant challenges. In this regard, we first explore 215 acoustic features from emotional speech. Second, we carry out speaker normalization and feature selection to develop a shared standard acoustic parameter set for multiple languages. Third, we use a three-layer model composed of acoustic features, semantic primitives, and emotion dimensions to map acoustics into emotion dimensions. Finally, we classify the continuous emotion dimensional values into basic categories by using the logistic model trees. The proposed approach was tested on Japanese, German, Chinese, and English emotional speech corpora. The recognition performance was examined and enhanced by cross-speaker and cross-corpus evaluation, and stressed the fact that our strategy is particularly suited for the task of multilingual emotion recognition even with a different speaker or language. The experimental results were found to be reasonably comparable with those of monolingual emotion recognizers as a reference. |
