  • Measurement of the effects of temporal clipping on speech quality 
    Ding, Lijing; Radwan, Ayman; Samy El-Hennawey, Mohamed; A Goubran, Rafik (IEEE, 2006)
    This paper investigates the effects of temporal clipping on perceived speech quality. Temporal clipping usually results from voice activity detection (VAD), or line echo canceller's nonlinear processor, and the clipped ...
  • Non-intrusive single-ended speech quality assessment in VoIP 
    Ding, Lijing; Lin, Zhong; Radwan, Ayman; Samy El-Hennawey, Mohamed; A Goubran, Rafik (Elsevier, 2007)
    Evaluating speech quality in voice over Internet protocol (VoIP) in a non-intrusive manner is challenging, because it relies on a degraded speech signal only. In this paper, a parametric, non-intrusive VoIP speech quality ...
  • Nonintrusive Measurement of Echo-Path Parameters in VoIP Environments 
    Ding, Lijing; Samy El-Hennawey, Mohamed; A Goubran, Rafik (IEEE, 2006)
    This paper proposes two echo-path delay measurement methods suitable for voice-over-Internet-protocol environments, where the echo suffers from excessive delay and nonlinear distortion. The proposed methods aim at greatly ...
  • Performance Study of Objective Voice Quality Measures in VoIP 
    Ding, Lijing; Radwan, Ayman; Samy El-Hennawey, Mohamed; A Goubran, Rafik (IEEE, 2007)
    With the advent of voice over internet protocol (VoIP) service, assessing its voice quality is an area of intense research interest. Due to time-consuming and expensive natures of widely accepted subjective mean opinion ...
