Enhanced Speech Emotion Recognition through Convolutional Neural Networks
Bibliographic record
Abstract
Identifying emotions in speech is a vital task in contemporary computing. This project focuses on finding the emotion of the human using his voice and improving humancomputer interaction. This paper presents speech emotion recognition in a new approach by integrating four different datasets.By combining the four datasets, RAVDESS (Ryerson Audio-Visual Database of Emotional Speech and Song), TESS (Toronto Emotional Speech Set), SAVEE (Surrey Audio-Visual Expressed Emotion), and CREMA-D (Crowd-sourced Emotional Multimodal Actors Dataset), and utilizing CNN (Convolutional Neural Network), our model extracts the features in the voice sample given, and by adding different datasets that contain different emotions, environmental conditions, and modulations, the model becomes robust and more generalized, with thorough experimentation, we show the accuracy of each emotion recognized by our system from various speech signals.Through the integration of varied datasets and employing sophisticated machine learning methodologies, our system not only discerns fundamental emotions but also captures nuanced emotional indicators, facilitating more profound and empathetic engagements between individuals and computational systems within an academic framework.In total, our work contributes to a little improvement of the SER research by offering a thorough approach to recognizing emotion from speech signals. The results shown by proposed model is $90 \%$ of accuracy. In this system it is capable of identifying the emotion accurately, which ensures that there is an efficient interaction between the human and computers.Furthermore, it uses smart methods to pick up all the different parts of speech that show emotions.This helps computers understand people better, so they can respond more accurately and make conversations smoother.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
