Abstract

In this paper we focus on the enhancement of speech quality by hands-free audio systems in modern, multimedia enabled telecommunication terminals. Requirements like the compatibility with wideband audio and full-duplex hands-free operation demand for sophisticated system designs. As a starting point we introduce a state-of-the-art system developed for mobile phones, considering practical aspects of algorithm design. Algorithmic extensions to this solution are presented, supporting speech enhancement for the user of the terminal or reducing the round-trip delay. In addition, more advanced concepts are discussed. They offer the capability of joint design for the most important algorithms and provide the possibility to exploit psychoacoustic properties of the human ear.
