dcterms:description
New results of speech transmission quality measurements obtained by a recently developed algorithm POLQA - ITU-T P.863 are presented. Our research shows acceptable accuracy for databases containing significant portion of low bit-rate coded samples, namely by MELPe 2.4 kbit/s. The POLQA results are compared with subjective test results based on ITU-T P.800.
