Non-Intrusive Speech Quality with Different Time Scale
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2012, Vol 2, Issue 5
Abstract
Speech quality evaluation is an extremely important problem in modern communication networks. Service providers always strive to achieve a certain Quality of Service (QoS) in order to ensure customer satisfaction. Modeling the speech quality becomes an urgent issue. In this project a computable model for different time scale speech quality evaluation, called E-Model is developed. The results indicate that subjects can monitor speech quality variations very accurately with a delay of approximately 1 second. Non-intrusive speech quality is measured at the receiver from a degraded signal using G.107 (E-model) which is a parameter based model and calculate MOS values with quality rating factor. The quality rating factor is calculated by network impairments (loudness rating) of a speech. The output from the model described here is a scalar quality rating value, R, which varies directly with the overall conversational quality. The key contribution of this paper is to explore the use of G-107 (E-model) based features for different time scale non-intrusive speech quality evaluation using time varying loudness of a speech for long stimuli. Sectional speech quality is obtained by Emodel, which is called instantaneous quality of the section that will be constant for each section. Overall perceived quality can be calculated by using average of instantaneous speech quality
