Abstract
Abstract: Speech emotion recognition (SER) plays a crucial role in human-computer interaction, enabling systems to in- terpret and respond to user emotions effectively. In human- computer interaction, speech emotion recognition (SER) is es- sential because it allows systems to efficiently understand and react to user emotions. In this research, we introduce Audio Aura, a machine learning-based system for voice signal emotion classification. To improve classification accuracy and extractrich speech representations, the system uses a transformer-based model called Wav2Vec2. By leveraging Wav2Vec2’s self- supervised learning capabilities, Audio Aura effectively captures temporal and contextual features in speech. The Toronto EmotionalSpeechSet(TESS)datasetisusedtotrainandassess the system, and it shows remarkable accuracy in recognizing emotions like neutrality, anger, sadness, and happiness. Com- pared to traditional machine learning approaches, transformer- based models demonstrate significant improvements in affective computing, making SER applications more robust in real-world scenarios

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.
