Recommended by Ricardo Merched We propose an objective method to assess speech quality in the conversational context by taking into account the talking and listening speech qualities and the impact of delay. This approach is applied to the results of four subjective tests on the effects of echo, delay, packet loss, and noise. The dataset is divided into(More)
Recently, new objective speech quality evaluation methods which integrate perceptual dimensions have been developed in order to provide diagnostic information about specific aspects of the transmission systems' quality. In this paper, we present two approaches, one (DIAL) built explicitly on blocks corresponding to perceptual dimensions and the other one(More)
This paper presents the performance of quality degradation indicators to be used in the context of super-wideband (50-14000 Hz) telephony. After an overview of these indicators, two analyses are undertaken: the first one considers conditions containing a single degradation and the second one considers conditions comprising several degradations at the same(More)
