Comparison of two objective speech quality measures: MBSD and ITU-T Recommendation P.861
نویسندگان
چکیده
The Modified Bark Spectral Distortion (MBSD), used for an objective speech quality measure, was presented previously [1, 2]. The MBSD measure estimates speech distortion in loudness domain taking into account the noise masking threshold in order to include only audible distortions in the calculation of the distortion measure. Preliminary simulation results have shown improvement of the MBSD over the conventional BSD. In this paper, the performance of the MBSD is improved by scaling the noise masking threshold. Finally, this new MBSD (MBSD II) measure is compared with the ITU-T Recommendation P.861 objective speech quality measure for telephone-band speech [3].

متن کاملA simplified version of the ITU algorithm for objective measurement of speech codec quality
ITU-T Recommendation P.861 describes an objective speech quality assessment algorithm for speech codecs [1]. This algorithm transforms codec input and output speech signals into a perceptual domain, compares them, and generates a noise disturbance value, which can be used to estimate perceived speech quality. The performance of this algorithm can be judged by the correlation between those estim...
متن کاملPerceptual Evaluation of Speech Quality (PESQ), the new ITU standard for end-to-end speech quality assessment. Part II – Psychoacoustic model
A new model for perceptual evaluation of speech quality (PESQ) was recently standardised by the ITU-T as recommendation P.862. Unlike previous codec assessment models, such as PSQM and MNB (ITU-T P.861), PESQ is able to predict subjective quality with good correlation in a very wide range of conditions, that may include coding distortions, errors, noise, filtering, delay and variable delay. Thi...
متن کاملA Computational Model for Mos Prediction
A computational model to predict MOS of processed speech is proposed. The system measures the distortion of processed speech (compared to the source speech) using a peripheral model of the mammalian auditory system and a psychophysically-inspired measure, and maps the distortion value onto the MOS scale. This paper describes our attempt to derive a “universal”, database-independent, distortion-...
متن کاملPerceptual evaluation of speech quality (PESQ)-a new method for speech quality assessment of telephone networks and codecs
Previous objective speech quality assessment models, such as bark spectral distortion (BSD), the perceptual speech quality measure (PSQM), and measuring normalizing blocks (MNB), have been found to be suitable for assessing only a limited range of distortions. A new model has therefore been developed for use across a wider range of network conditions, including analogue connections, codecs, pac...
