| Metodología de prueba subjetiva para evaluar los sistemas de comunicación vocal que utilizan un algoritmo de cancelación de ruido |
 |
En esta Recomendación se describe una metodología para evaluar la calidad subjetiva de la voz en presencia de ruido y, en particular, para la evaluación de los algoritmos de cancelación de ruido. En la metodología se utilizan escalas de puntuación diferentes para estimar por separado la calidad subjetiva de la señal de voz, el ruido de fondo y la calidad global. |
