Abstract
We introduce a new paradigm for Robust Automatic Speech Recognition that directly incorporates information about the uncertainty introduced by environmental noise. In contrast to the feature cleaning and model adaptation paradigms, where the noise compensation mechanism is separate from the recognizer, the new paradigm unifies the noise compensation mechanism and the recognizer. The Algonquin framework serves to demonstrate the importance of retaining soft information, i.e. information about the degree of uncertainty in the observations. The Algonquin framework employs Gaussian mixture models to model both noise and speech. Uncertainty introduced by the noise process is captured by the variance of the noise model. The Algonquin framework also allows us to isolate the effect of retaining or discarding soft information. Our initial results indicate that substantial improvements in recognition rates can be achieved through the use of soft information.

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
