A THEORETICAL ARCHITECTURE OF VOICEPRINT RECOGNITION FOR NETWORK SECURITY SITUATIONAL AWARENESS

This paper proposes a theoretical framework for DenseNet-based voiceprint recognition, which incorporates spectrogram enhancement and adaptive histogram equalization to overcome the limitations of conventional methods in feature extraction robustness under noisy conditions. The framework synergistically combines spectral feature enhancement with DenseNet's dense connectivity, achieving both improved feature discriminability and deep feature reuse through: optimized time-frequency representation via enhanced spectrograms, hierarchical feature propagation enabled by dense blocks. Theoretical analysis confirms the framework's capability to maintain recognition stability against acoustic interference, establishing a novel biometric authentication paradigm for cybersecurity situational awareness systems.
