Abstract
Human speech is not only a verbose medium of communication but it also conveys emotions. The past decade has seen a lot of research going on with speech data which becomes especially important for human-computer interaction and also healthcare, security and entertainment. This paper proposes the TLEFuzzyNet model, a three-stage pipeline for emotion recognition from speech. The first stage includes feature extraction by data augmentation of speech signals and extraction of Mel spectrograms, followed by the use three pre-trained transfer learning CNN models namely, ResNet18, Inception_v3 and GoogleNet whose prediction scores are fed to the third stage. In the final stage, we assign Fuzzy Ranks using a modified Gompertz function which gives the final prediction scores after considering the individual scores from the three CNN models. We have used the Surrey Audio-Visual Expressed Emotion (SAVEE), the Ryerson Audio-Visual Database of Emotional Speech and Song (RAVDESS) and the Berlin Database of Emotional Speech (EmoDB) datasets to evaluate the TLEFuzzyNet model which has achieved state-of-the-art performance and is hence a dependable framework for Speech emotion recognition(SER). All the codes are available using GitHub link: https://github.com/KaramSahoo/SpeechEmotionRecognitionFuzzy.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
