Abstract

Un método de clasificación de señales de audio basado en marcos o cuadros, caracterizado por los pasos de: determinar (S1), para cada uno de un número predeterminado de marcos consecutivos, medidas de características que representan al menos las siguientes características: - un coeficiente de auto-correlación (Tn), - una energía de señal de marco (En) en un dominio comprimido, - una variación de energía entre marcos; comparar (S2) cada medida de característica determinada con al menos un correspondiente intervalo predeterminado de características; calcular (S3), para cada intervalo de características, una medida de fracción (Φ ;1 - Φ 5) que representa el número total de medidas correspondientes de características (Tn, En, Φ ;;En) que caen dentro del intervalo de características; clasificar (S4) el último de los marcos consecutivos como habla si cada medida de fracción se sitúa dentro de un intervalo de fracción correspondiente, y como no-habla en caso contrario.
