Abstract
UN DETECTOR DE ACTIVIDAD VOCAL (26) QUE CONSTA DE UNA ENTRADA PARA LA RECEPCION DE LA SEÑAL DE VOZ DE SALIDA QUE ES TRANSMITIDA DESDE UN SISTEMA DE VOZ (2) HACIA UN USUARIO, Y DE UNA ENTRADA PARA RECIBIR UNA SEÑAL ENTRANTE PROCEDENTE DE DICHO USUARIO. AMBAS SEÑALES DE ENTRADA Y SALIDA SE DIVIDEN EN TRAMAS LIMITADAS EN EL TIEMPO. SE PROPORCIONAN MEDIOS (263) PARA CALCULAR UNA CARACTERISTICA DE CADA TRAMA DE LA SEÑAL ENTRANTE Y PARA FORMAR UNA FUNCION DE LA CARACTERISTICA CALCULADA Y UN NIVEL UMBRAL. BASADO EN LA FUNCION, SE DETERMINA SI LA SEÑAL ENTRANTE INCLUYE VOZ O NO. SE PROPORCIONAN TAMBIEN MEDIOS PARA DETERMINAR LAS PERDIDAS POR RETORNO DE ECO DURANTE EL ENVIO DE LA SEÑAL DE VOZ DE SALIDA DESDE EL SISTEMA INTERACTIVO DE VOZ Y PARA CONTROLAR EL NIVEL UMBRAL EN FUNCION DE LA MEDIDA DE DICHAS PERDIDAS POR RETORNO DE ECO.
