Počta, P. - Holub, J. - Mrvová, M.: Impact of Different Active-Speech-Ratios on PESQ's Predictions in Simulated VoIP Environment. ACTA ACUSTICA UNITED WITH ACUSTICA . 2009, vol. 95, no. 5, p. 950-958. ISSN 1610-1928
In this work, we experimentally study how behaviour of the PESQ predictions varies with reference signal characteristic.
In particular we investigate the impact of different Active-Speech-Ratios on speech quality prediction
in simulated VoIP environment from objective and subjective testing point of view. This reference signal characteristic
is defined very broadly by ITU-T Recommendation P.862.3. That is the reason to investigate an impact
of this characteristic on speech quality prediction more in-depth. We assess the variability of PESQ’s predictions
with respect to Active-Speech-Ratio and network conditions, as well as their accuracy, by comparing the
predictions with subjective assessments.
