DOI: 10.1007/s10772-019-09658-x
Abstract: Biometric template protection of speech signals and information hiding in speech signals are two challenging issues. To resolve such limitations and increase the level of security, our objective is to build multi-level security systems based… read more here.

DOI: 10.1016/j.apacoust.2021.108328
Abstract: Abstract Compressive sensing (CS) is a technique that can achieve exact signal reconstruction by using fewer samples than those in the Nyquist theorem. In this study, listening tests were conducted to investigate the minimum number… read more here.

DOI: 10.1109/lsp.2017.2782267
Abstract: This letter introduces a method based on the Hilbert–Huang transform (HHT) to estimate the fundamental frequency of nonstationary noisy speech signals. For this purpose, the target signals are analyzed by means of the ensemble empirical… read more here.

DOI: 10.1109/lsp.2022.3217727
Abstract: Most robust steganographic methods pursue insignificantly zero-bit error rate of hidden messages for ensuring the reliability of communication. Cover JPEG images are required to recompress many times for enhancing the robustness, that reduces the security.… read more here.

DOI: 10.1523/eneuro.0399-20.2020
Abstract: Abstract Speech signals have a unique shape of long-term modulation spectrum that is distinct from environmental noise, music, and non-speech vocalizations. Does the human auditory system adapt to the speech long-term modulation spectrum and efficiently… read more here.
