Detecting infant crying from ambient audio for smart nursery monitors. Privacy-preserving since audio is classified on-device without cloud streaming — parents are alerted locally without recordings leaving the device. Distinguishes cry from other household sounds like TV, music, or pet noise using mel-spectrogram features and lightweight CNN classifiers. Low power consumption enables battery-operated monitor deployments.
