Hodnocení kvality hovoru E-modelem

Abstract

This bachelor thesis is focused on the analysis of different technics for evaluation of speech quality, mainly on computational model called E-model. The first part of this work contains an overview of subjective and objective methods for evaluation, including their main delegates and description of their functions. The next part of this work describes whole computation cycle of E-model corresponding with ITU-T G.107 recommendation, including description of all its components and parametres. The last part is focused on simulation of quality using E-model and on comparison with results obtained by objective intrusive method called PESQ. Document also contains design and implementation of application simplifying computation of E-model and it also contains model of correction function for matching values obtained by E-model and PESQ method. Evaluation of obtained results and achieved goals can be found at the end of this work.
