Abstract
With the advancements in deep learning and other techniques, synthetic speech is getting closer to a natural sounding voice. Some of the state-of-art technologies achieve such a high level of naturalness that even humans have difficulties distinguishing real speech from computer generated speech. Moreover, these technologies allow a person to train a speech synthesizer with a target voice, creating a model that is able to reproduce someone’s voice with high fidelity.In this paper, we introduce the FoR Dataset, which contains more than 198,000 utterances from the latest deep-learning speech synthesizers as well as real speech. This dataset can be used as base for several studies in speech synthesis and synthetic speech detection. Due to its large amount of utterances, it is pertinent for machine learning studies, since it is able to train even complex deep learning models without overfitting. We present several experiments using this dataset, including a deep learning classifier that reached up to 99.96% accuracy in synthetic speech detection.

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
