Effect of speech activity parameter on PESQ's predictions in presence of independent and dependent loses
Autor: Počta, P.; Holub, J.
(2013)This paper deals with the investigation of PESQ's (Perceptual Evaluation of Speech Quality; also known as ITU-T Recommendation P.862) behavior under independent and dependent loss conditions from a speech activity parameter ... -
Impact of Different Active-Speech-Ratios on PESQ’s Predictions in Case of Independent and Dependent Losses (in Presence of Receiver-Side Comfort-Noise)
Autor: Počta, P.; Holub, J.; Vlčková, H.; Polková, Z.
(2010)This paper deals with the investigation of PESQ’s behavior under independent and dependent loss conditions from an Active-Speech-Ratio perspective in presence of receiver-side comfort-noise. This reference signal ... -
Impact of Different Active-Speech-Ratios on PESQ’s Predictions in Simulated VoIP Environment
Autor: Počta, P.; Holub, J.; Mrvová, M.
(2009)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 ... -
Predicting the Quality of Synthesized and Natural Speech Impaired by Packet Loss and Coding Using PESQ and P.563 Models
Autor: Počta, P.; Holub, J.
(2011)This paper investigates the impact of independent and dependent losses and coding on speech quality predictions provided by PESQ (also known as ITU-T P.862) and P.563 models, when both naturally-produced and synthesized speech ...
