Abstract

Procedimiento de supresión de ruido de una señal numérica de palabra (s) tratada por trazas sucesivas, en el cual: se efectúa un análisis armónico de la señal de palabra para estimar una frecuencia tonal (fp) dela señal de palabra en cada trama donde presenta actividad vocal; se calculan unas componentes espectrales (Sn;f , Sn;i ) delaseñal de palabra en cada trama; se calculan para cada trama, unas estimaciones de componentes espectrales del ruido comprendidas en la señal de palabra; se efectúa una sustracción espectral que comprende por lo menos una etapa que consiste en sustraer respectivamente, de cada componente espectral de la señal de palabra de la trama (Sn;f ), una cantidad que depende de parámetros que incluyen por lo menos la estimación de la componente espectral correspondiente al ruido para dicha trama y el valor de la frecuencia tonal estimada.
