Description
The paper analyzes the possibility of restoring speech information masked by active vibroacoustic noise using wavelet-based digital signal processing. A three-stage procedure including test signal synthesis, wavelet transformation, and inverse wavelet denoising is investigated. Results demonstrate preservation of speech allophone structure even at low SNR levels, indicating potential risks for speech information leakage despite active masking systems.
