Abstract
Speaker recognition technology, deployed in sectors like banking, education, recruitment, immigration, law enforcement, and healthcare, relies heavily on biometric data. However, the ethical implications and biases inherent in the datasets driving this technology have not been fully explored. Through a longitudinal study of close to 700 papers published at the ISCA Interspeech Conference in the years 2012 to 2021, we investigate how dataset use has evolved alongside the widespread adoption of deep neural networks. Our study identifies the most commonly used datasets in the field and examines their usage patterns. The analysis reveals significant shifts in data practices since the advent of deep learning: a small number of datasets dominate speaker recognition training and evaluation, and the majority of studies evaluate their systems on a single dataset. For four key datasets–Switchboard, Mixer, VoxCeleb, and ASVspoof–we conduct a detailed analysis of metadata and collection methods to assess ethical concerns and privacy risks. Our study highlights numerous challenges related to sampling bias, re-identification, consent, disclosure of sensitive information and security risks in speaker recognition datasets, and emphasizes the need for more representative, fair, and privacy-aware data collection in this domain.

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
