Symbian Based Perceptual Evaluation of Speech Quality for Telecommunication Networks

Evaluation and Validation of a New Perceptual Speech Quality Measure for Speech Enhancement

Analysis of denoised speech using enhancement algorithms shows the presence of two kinds of degradation: speech distortion and residual background noise. Due to the fact that objective criteria are not able to evaluate separately them, we tested one composite criteria and we proposed a novel couple separating speech distortion and residual background noise. Firstly, we show the ability of propo...

Perceptual evaluation of alaryngeal speech.

The aim of this study was to compare the self-assessed vocal handicap of laryngectomees treated with three different communication methods: tracheoesophageal speech, esophageal speech and electrolarynx. Forty-eight patients, 40 males and 8 females, who had undergone total laryngectomy for laryngeal carcinoma were enrolled in the study. Depending on the voice restoration method, all patients wer...

Perceptual 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...
