Cross lingual speech emotion recognition using canonical correlation analysis on principal component subspace

This paper proposes an analytical approach based on Kernel Canonical Correlation Analysis (KCCA) for domain adaptation. To generate paired instances for KCCA, we mapped source and target data onto both source and target principal components. We performed pair-wise domain adaptation between four emotional speech corpora with different languages (English, German, Italian, and Polish) to validate the approach. We compared our approach with the Shared-Hidden-Layer Auto-Encoder (SHLA) and kernel based principal components. On average, the proposed approach yields higher classification performance.
