| Guía para la aplicación de la Recomendación UIT-T P.863 |
En la Recomendación UIT-T P.863.1 figuran observaciones importantes que conviene tener en cuenta en las evaluaciones objetivas de la calidad vocal de acuerdo con la Recomendación UIT-T P.863. Sería conveniente que los usuarios de la Recomendación UIT-T P.863 comprendieran y siguieran los consejos que se dan en esta Recomendación.
Esta Recomendación constituye una guía complementaria para usuarios de la Recomendación UIT-T P.863, en la que se describe un mecanismo para evaluar la calidad vocal en escucha utilizando muestras vocales de referencia y degradadas. El alcance de la Recomendación UIT-T P.863 está claramente definido en sí mismo. La presente Recomendación ni amplía ni reduce el alcance de la misma, sino que ofrece información importante y necesaria para obtener en la práctica resultados estables, fiables y significativos con las mediciones objetivas. |
