Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA REDUCIR LAS INTERFERENCIAS DE UNA SEÑAL VOCAL UTILIZANDO PARA ELLO UN PROCEDIMIENTO DE REDUCCION DE RUIDOS, DONDE SE PROPONE DETERMINAR SENDAS CURVAS DE RECUBRIMIENTO TANTO PARA LA SEÑAL DE ENTRADA COMO DE LA SEÑAL DE SALIDA DE LA REDUCCION DE RUIDOS. COMPARANDO LOS COMPONENTES DE LA SEÑAL QUE REBASEN LA RESPECTIVA CURVA DE RECUBRIMIENTO SE PUEDEN DETECTAR EN LA SEÑAL DE SALIDA NUEVAS PROPORCIONES AUDIBLES COMO INTERFERENCIAS A MODO DE TONOS MUSICALES, QUE A CONTINUACION SE PUEDEN ATENUAR DE FORMA SELECTIVA.
