Abstract

fetched live from OpenAlex

Abstract A perpetrator speaking over the telephone or one whose face was obscured or disguised are examples of incidents that might lead to testimony on voice identification. Earwitness identification is part of the general area of person identification, but refers specifically to victims' and witnesses' verbal descriptions of voices and speaker identification. Although many laypersons give significantly more credibility to the identification of speakers than is justified, experts generally agree that earwitness descriptions and identification should be treated by the criminal justice system with great caution. This article presents a scientific overview of factors that affect the accuracy of speaker identification, or what is referred to as aural-perceptual analysis, and discusses the reliability and validity of speaker recognition and identification. The police do not have the luxury of handpicking their witnesses (or culprits) but must interview any and all male and female victims or witnesses, all of whom can differ in age, race, expertise, and other characteristics. The article also considers showups and voice lineups.

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.
