Abstract

"This paper deals with the application of the Kohonen Self-Organizing Maps (KSOM) to methods of objective speech quality assessment. The performance of the objective methods so far proposed depends on many factors, among which the required mapping between the objective and subjective domains is one of the most important. The purpose of this paper is to present new results about application of the KSOM networks to replace the traditional third-order polynomial mapping. Some distinct network topologies and techniques for the extraction of the signal parameters are presented and tested in the context of the \u201cMedida Objetiva de Qualidade de Voz\u201d (MOQV) objective method applied to situations present in a traditional database."
