Boundary-Robust Lightweight Speech Command Recognition via Adaptive Noise-Floor Estimation and Reliability-Conditioned Cross-Scale Fusion
This paper presents a boundary-robust lightweight speech-command recognizer based on adaptive quantile noise-floor estimation (AQNE) and reliability-conditioned cross-scale interaction fusion (RCIF). AQNE estimates the noise floor from the lowest-energy 20% of overlapping frames and provides both SNR and reliability cu...
