Abstract

Aiming at the problem of insufficient utilization of speech information in speech emotion recognition, this paper proposed a speech emotion recognition model that integrated multi-level features of speech, calced MFTA. This model could handle various features of speech and eventually conduct feature fusion. The introduced time attention mechanism utilized the correlation of speech in the frequency domain and the time domain to achieve the goal of making full use of speech signals. The experimental results show that the multi-level feature information of speech can mine the depth information in speech better. By introducing the temporal attention mechanism, this model can align the audio domain signals of speech and the timedomain signals to achieve the purpose of improving the effect of emotion recognition. MFTA outperforms existing methods in recent years when performing speech emotion recognition tasks on the IEMOCAP and RAVDESS dataset, demonstrate the effectiveness of multi-level features and temporal attention. This research provides new ideas for the speech signal processing mode.
