Conversational Speech Quality in Noisy Environments

The present study reports on a conversation test conducted to reveal insights on how telephony users perceive speech transmission quality in a noisy environment. For this purpose, a telephony setup has been built to simulate different degradations typical of real-life situations. A range of different conditions has been presented during the subjective test including usage of different terminals, environmental noises, and a noise suppression algorithm. A noise reproduction system has been installed on one side of the telecommunication channel to create an immersive noisy environment. Special focus of this paper is on the influence of different terminal devices and their signal processing on subjective quality. Moreover, more generic conclusions regarding conversational quality testing are provided.
