AbstractIn this paper, we explore a new voice quality management model under ambience environment suitable for voice over internet protocol (VoIP) calls in wireless WLAN 802.11 Linux environment. The system is based on a setup that assimilates environment noise level using noise detector and adaptive audio manager used to tune the audio level and thereby quality is ensured. Further, existing models such as E-model, PESQ model and adaptive model address QoS in a VoIP networking perspective but do not address voice quality management in real time environment to improve voice quality. We propose to use background noise and its associated source information in an adaptive environment to boost user perception, audio level, thereby ensuring quality. This issue is important because in real time, consumers might be interested in mobiles that address ambience effect to determine human audible effect based on environment conditions. The experimental results of the proposed method outperform the existing method in t...
