| Evaluación subjetiva de la calidad de la conversación |
La Recomendación UIT-T P.805 describe métodos y procedimientos para realizar pruebas conversacionales con el fin de evaluar la calidad de la comunicación. En la metodología se utilizan ejemplos de hipótesis, escalas de puntuación y procedimientos de análisis para estimar la calidad subjetiva de los servicios de telecomunicaciones interactivos o bidireccionales. Las pruebas conversacionales permiten simular situaciones más realistas próximas a las condiciones de servicio reales experimentadas por los usuarios de telecomunicaciones. Además, las pruebas conversacionales están diseñadas para evaluar los efectos de las degradaciones que pueden causar dificultades durante la conversación (tales como retardo, pérdida de paquetes, eco, interrupciones, ruido, recortes vocales, etc.) y pueden utilizarse para estudiar los efectos generales del sistema o las degradaciones específicas. |
