Abstract

fetched live from OpenAlex

In this paper we present an modified enhanced speech enhancement algorithm based on linear prediction(LP) residual so as to reduce the annoyance additive noise.When linear prediction analysis was done under various noise conditions,it is easy to find that the linear prediction coefficients carry spectrum and formant infor-mation.Several experiments indicate that the prediction coefficients in the noise position are smaller than in the speech,and the sum of square of the linear prediction coefficients has an obvious trend to represent the instantaneous SNR of the noisy speech signal.In this work the sum of square is used in the denoising function derived from the idea of Wiener filter,then the denoising function and the method developed by B.Yegnanaraynana are combined to obtain the enhanced speech.The experimental result shows that the method achieved a preferable denoised speech retaining the speech intelligibility,and with less computation.

Not 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.
