Abstract
We investigate the use of deep neural nets (DNN) to provide initial speaker change points in a speaker diarization system. The DNN trains states that correspond to the location of the speaker change point (SCP) in the speech segment input to the DNN. We model these different speaker change point locations in the DNN input by 10 to 20 states. The confidence in the SCP is measured by the number of frame synchronous states that correspond to the hypothesized speaker change point. We only keep the speaker change points with the highest confidence. We show that this DNN-based change point detector reduces the number of missed change points for both an English test set and a French dev set. We also show that the DNN-based change points reduce the diarization error rate for both an English and a French diarization system. These results show the feasibility of DNNs to provide initial speaker change points.

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
