Abstract

fetched live from OpenAlex

Proposed in this work is the notion of spectral emotion profile. The purpose of spectral emotion profile is to highlight the spectral differences of individuals in expressing emotions, and to make use of those differences towards personalizing recognition of emotions in speech. To define spectral emotion profile, we have taken advantage of the spectral energy distribution as a set of speech features. To demonstrate the idea in a more sensible way, we have made use of two emotional speech datasets. Results of our experimental study based on the proposed notion of spectral emotion profile show how different spectral intervals of individual speakers, as well as those of different genders, vary in the amount to which they contribute to the expression of emotions. It is also shown that using spectral emotion profile results in higher prediction accuracy.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
