The Speech emotion recognition has become an outstanding frontier domain with applications that extend from human–computer interaction to mental health monitoring. However, the research in this domain is known to be extensive with little specific focus on languages like Tamil, which has rich emotional complexity. Thus, this paper seeks to look over the Speech Emotion Recognition for the Tamil language in detail. This study involves several significant steps in the methodology, namely: preprocessing of speech signals, data augmentation, feature extraction from signals, such as Mel-frequency cepstral coefficients (MFCCs). Classification into various emotions is done using a deep learning model such as a convolutional neural network (CNN), long short-term memory network (LSTM) and Bidirectional long-short term memory (Bi-LSTM). Tamil speech samples labelled with emotional labels are used to evaluate the SER system. Performance is measured by accuracy, precision, recall, and F1-score. The results will indicate whether the proposed approach is effective in accurately recognizing emotions from the speech signals of the Tamil language. Thus, this study underlines the significance of modeling techniques specific to language in capturing emotional expression in the Tamil language. Significant implications in the development of emotionally intelligent systems tailored for Tamil-speaking populations, such as virtual assistants and mental health support applications, arise from these results.
