Abstract

fetched live from OpenAlex

In recent years speech synthesis has comes out with great prominence. There are two approaches to generate synthetic speech: waveform based and parameter based. Waveform based approach uses pre-recorded sentences of speech and plays a part of these sentences in a prescribed sequence for generating the desired speech output. Harmonic plus noise model (HNM) is a variant of parameter based approach. In parameter based approach synthetic speech is generated using parameters, there is no need of the recorded wav or raw files. Harmonic plus noise model divides the spectrum of the speech into two sub-bands, one is modeled with harmonics of the fundamental frequency and the other is synthesized using random noise. Maximum voiced frequency is used to discriminate between harmonics and noise part. harmonics and noise are also known as periodic and non-periodic parts.

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.
