We discuss objective estimation methodologies for subjective quality of wideband speech. First, the wideband extension of the current ITU-T Recommendation P.862, which provides a means for objectively estimating subjective quality, is evaluated from the viewpoint of assessing the effects of band limitation. Then, the validity of the objective assessment is discussed based on the subjective quality database, which includes practical degradations assumed in VoIP applications.
