چکیده

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 objetive assessment is discussed based on the subjective quality database, which includes practical degradations assumed in VoIP applications.

Objective Quality Assessment of Wideband Speech Coding using W-PESQ Measure and Artificial Voice

An objective quality measurement methodology for wideband-speech coding has been studied, its essential components being an objective quality measure and an input test signal. Wideband-PESQ conforming to draft Recommendation P.862 has been studied as the objective quality measure. The Wideband-PESQ has been verified from the viewpoint of the consistency between subjectively evaluated MOS and ob...

Validating Perceptual Objective Listening Quality Assessment Methods on the Tonal Language Igbo

In recent years a great deal of effort has been expended to develop methods that determine speech quality through the use of comparative algorithms. These methods are designed to calculate an index value of quality that correlates to a mean opinion score given by human subjects in evaluation sessions. In this paper, we validate Perceptual Evaluation of Speech Quality (PESQ) ITU-T Recommendation...

Microsoft Word - A novel super-wideband embedded speech and audio c

This paper proposes a multi-layer super-wideband embedded speech and audio coding algorithm extending bit rates from 36 to 64 kb/s on the basis of ITU-T Recommendation G.729.1 with a multi-stage coding structure. This codec consists of three embedded stages: G.729.1 wideband coding operating in the range from 8 to 32 kb/s, modified Modulated Lapped Transform (MLT) coding of the band (7-14 kHz) ...
