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 are used. Two synthesized speech samples generated with two different Text-to-Speech systemsand one naturally-produced sample are investigated. In addition, we assess the variability of PESQ’s and P.563’spredictions with respect to the type of speech used (naturally-produced or synthesized) and loss conditions aswell as their accuracy, by comparing the predictions with subjective assessments. The results show that there isno difference between the impact of packet loss on naturally-produced speech and synthesized speech. On theother hand, the impact of coding is different for the two types of stimuli. In addition, synthesized speech seemsto be insensitive to degradations provided by most of the codecs investigated here. The reasons for those findingsare particularly discussed. Finally, it is concluded that both models are capable of predicting the quality of transmittedsynthesized speech under the investigated conditions to a certain degree. As expected, PESQ achieves thebest performance over almost all of the investigated conditions
