Abstract
Vocal imitation is often described as a specialized form of learning that facilitates social communication and that involves less cognitively sophisticated mechanisms than more "perceptually opaque" types of imitation. Here, we present an alternative perspective. Considering current evidence from adult mammals, we note that vocal imitation often does not lead to learning and can involve a wide range of cognitive processes. We further suggest that sound imitation capacities may have evolved in certain mammals, such as cetaceans and humans, to enhance both the perception of ongoing actions and the prediction of future events, rather than to facilitate mate attraction or the formation of social bonds. The ability of adults to voluntarily imitate sounds is better described as a cognitive skill than as a communicative learning mechanism. Sound imitation abilities are gradually acquired through practice and require the coordination of multiple perceptual-motor and cognitive mechanisms for representing and generating sounds. Understanding these mechanisms is critical to explaining why relatively few mammals are capable of flexibly imitating sounds, and why individuals vary in their ability to imitate sounds.

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
