Abstract
Mobile telephony is often conducted in the presence of acoustical background noise such as traffic or babble noise. The near-end listener perceives a mixture of clean far-end (downlink) speech and background noise at the near-end side. Thus, the user experiences an increased listening effort and possibly a reduced speech intelligibility. This situation can be improved by adaptive signal processing of the far-end signal, which we call near-end listening enhancement (NELE). In our real-time demonstration the visitor will experience the strong improvement in the acoustic conference/exhibition environment. The adaptive algorithm optimizes the intelligibility of the far-end speech even in instationary background noise with respect to the objective criterion Speech Intelligibility Index (SII). In contrast to state-of-the-art techniques, the presented method considers the requirements and restrictions of realistic scenarios such as in mobile phones.
