Measurement of imitation similarity to a physiological phenomenon

Spectral analysis of two audio signals, MFCC + spectrum + envelope feature vector, cosine distance. Score 0–100 on the IIP-2026 scale.

This procedure objectively determines whether an acoustic imitation of the pneumological phenomenon, executed prior to observing the original, falls within a similarity class permitting classification as "matched". The trial measures a participant's capacity to anticipate their own signal with an accuracy beyond the reach of subjective observer perception.
