Comparison of Objective Assessment Methods for Intelligibility and Quality of Speech

Subjective rating of the quality of speech in narrow-band telecommunication is parametrically assessed by the so-called E-model [1]. Intelligibility of the speech signal transmitted has a significant impact on the opinion of users [2]. The Speech Intelligibility Index [3] quantifies the amount of speech perceptual features available to the listener in conditions with background noise and linear frequency distortion. It has shown to be highly correlated with subjective speech recognition performance. This paper proposes a comparison between both models. It refers to, and details, improvements towards the modeling of quality in wide-band transmission [4], [5].
