Spectral envelope estimation of high-pitched vowels using a shared excitation proxy and autoregressive modeling with exogenous input.

Characterizing the vocal tract spectral envelope in high-pitched vowels is challenging due to sparse harmonics and source-filter coupling. This study proposes an analytical framework using a shared glottal driving proxy to guide source-tract decoupling. Speech is decomposed into multi-band Hilbert envelopes; first-orde...

Construction of a Small Model Based on Large Model Knowledge Distillation in Anomaly Behaviour Recognition for Intelligent Connected Vehicles

Experimental results validate the feasibility of transferring knowledge from large models under low-computational-power constraints and provide a new technical pathway and engineering reference for recognising anomalies at the edge of intelligent connected vehicles.
