Abstract
In the information era, Voice-over-IP (VoIP)streams have become the backbone of social media and multimedia interaction; their openness, however, also offers a stealth conduit for covert communication. This report dissects state-of-the-art steganographic techniques and their countermeasures in VoIP traffic, spotlighting the latest embedment strategies within modern speech codecs. We reveal how information is imperceptibly woven into speech signals and, leveraging deep learning, present high-accuracy detection models that reliably expose hidden payloads. Extensive experiments quantify the concealment capacity and perceptual impact of diverse steganographic algorithms, while systematically benchmarking the strengths and limitations of current detectors. Looking forward, we chart the convergence of artificial intelligence and next-generation coding paradigms, outlining emerging research avenues that will shape the future security of voice streams and steganalysis.
