| Méthodes d'évaluation objective des systèmes de communication vocale utilisant des signaux de test complexes |
 |
La présente Recommandation décrit des méthodes et des procédures d'évaluation de terminaux, de composants de réseaux et de systèmes de transmission complexes. Les méthodes de test utilisent, pour la plupart, les signaux de test décrits dans les Recommandations UIT-T P.50, P.59 et P.501. Pour diverses implémentations techniques et situations de conversation, on donne les incidences possibles sur la qualité vocale telle qu'elle est perçue subjectivement et on décrit les procédures de mesure correspondantes. |
