Abstract

This paper presents a new method for the objective quality assessment of speech signals, named Objective Assessment of Speech Signals (OASS). The proposal represents an improvement of a previous method (MOQV), with two new features: 1) a routine to detect and correct vmiable delays between the original and degraded signals: 2) a new psycho-acoustic model for the ear. The paper details the new routine to eliminate variable delays, the basic structure of the signal quality measure, the improvements introduced in the psycho-acoustical model and a new procedure to extract the cognitive difference between the signals. The paper also describes the tests perfornled to validate the method and respective performance parameters. OASS is compared to MOQV and also to PESQ, which is currently adopted as standard by International Telecommunication Union (ITU).
