Abstract

SE PRESENTA UN SISTEMA DE ANALISIS ESPECTRAL, VARIABLE DE TIEMPO PARA LA CODIFICACION DE LA VOZ BASADO EN LA INTERPOLACION ENTRE MARCOS DE VOZ. LA SEÑAL DE LA VOZ SE MODULA MEDIANTE UN FILTRO LINEAL QUE SE OBTIENE MEDIANTE UN ALGORITMO DE ANALISIS DE CODIFICACION PREDICTIVA, LINEAL, VARIABLE, DE TIEMPO. SE UTILIZA LA INTERPOLACION ENTRE MARCOS DE VOZ ADYACENTES PARA EXPRESAR UNA VARIACION DE TIEMPO DE LA SEÑAL DE LA VOZ. ADEMAS, LA INTERPOLACION ENTRE MARCOS ADYACENTES ASEGURA UN SEGUIMIENTO CONTINUO DE LOS PARAMETROS DEL FILTRO A TRAVES DE MARCOS DE VOZ DIFERENTES.
