| Evaluación subjetiva de la calidad de la señal vocal con un enfoque de externalización abierta |
En esta Recomendación UIT-T P.808 se describe un método para realizar evaluaciones subjetivas de la calidad del habla mediante externalización masiva. En comparación con las pruebas en laboratorio, las pruebas mediante externalización masiva dependen de los participantes, que se conectan mediante una plataforma en línea y cuya tarea es evaluar la calidad del habla en su propio entorno y con sus propios dispositivos. En esta Recomendación se dan orientaciones sobre el material de prueba, el diseño de los experimentos y el procedimiento para realizar pruebas de escucha masivas. Los métodos han de considerarse complementarios a las evaluaciones en laboratorio descritas en las Recomendaciones UIT-T P.800 y UIT-T P.835. |
