Abstract
The authors propose a novel method for improving the performance of ITU-T G.729A for Voice-over-IP (VoIP) applications. One of the most important features for a speech compression algorithm that is to be used for VoIP is that it be resistant to packet loss. Because of the memory that resides in the G.729A algorithm, a packet loss will not only cause degradations during the period of the loss but also following the packet loss due to the differing states of the encoder and decoder. The G.729A algorithm deals quite well with the packet loss period through error concealment, but it does not deal with the state error that follows the packet loss. The paper introduces a new scheme called recovery by reinitialization (RbR) that reduces this state error at minimal cost.

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
