Abstract :
This study investigates the potential of value-added speech communications by using steganography. The quality of speech communications based on VoIP may potentially be degraded by packet loss that is basically inevitable in best-effort communications. This study proposes a packet loss concealment technique for mitigating such degradation by using steganography. In addition, this study also proposes a band extension technique by using steganography.
