Abstract

Para clasificar distintos segmentos de una senal que comprende segmentos de por lo menos un primer tipo y un segundo tipo, por ejemplo, segmentos de voz y de musica, se clasifica la senal en un corto plazo (150) sobre la base de por lo menos un rasgo distintivo de corto plazo extraída de la senal y se entrega un resultado de clasificacion de corto plazo (152). La senal se clasifica también en un largo plazo (154) sobre la base de por lo menos un rasgo distintivo de corto plazo y por lo menos un rasgo distintivo de largo plazo extraídos de la senal y se entrega un resultado de clasificacion de largo plazo (156). Se combinan (158) el resultado de la clasificacion de corto plazo (152) y el resultado de la clasificacion de largo plazo (156) para proveer una senal de salida (160) que indica si un segmento de la senal es del primer tipo o del segundo tipo.
