AES Convention 113 · Paper 5658 · October 2002

Abstract

Contemporary means of communication (e.g. mobile telephony) have brought new limitations that telecom operators have to take into consideration. One of them is the fact that types of the deterioration of speech quality, perceived in mobile telephony, are different from the degradations noted in fixed telephony. During the process of estimating the quality of speech transmission, in this paper are used the comparative (objective) methods for a formed database of degradations of a real mobile communications system. The consideration of the results of the objective-method tests is based on the development of a new objective method of speech quality. The results gathered during the comparison tests have been displayed and interpreted for different types of Serbian vowels: front vowels, /e/; mid vowel, /a/; and back vowels, /u/.
