Abstract
SE PRESENTA UN METODO DE TRANSMISION (600) Y RECEPCION DE HABLA CODIFICADA EN EL QUE LAS MUESTRAS SE TOMAN (602) DE UNA SEÑAL DE HABLA (601) Y SE CALCULAN LOS COEFICIENTES DE REFLEXION (603) A PARTIR DE ESTAS MUESTRAS. CON EL FIN DE MINIMIZAR LA TASA DE TRANSMISION UTILIZADA, SE COMPARAN (606) LAS CARACTERISTICAS DE LOS COEFICIENTES DE REFLEXION CON LAS RESPECTIVAS CARACTERISTICAS ESPECIFICAS DE SONIDOS ALMACENADAS (624) DE LOS COEFICIENTES DE REFLEXION PARA IDENTIFICACION DE LOS SONIDOS Y SE TRANSMITEN (617) LOS IDENTIFICADORES DE LOS SONIDOS IDENTIFICADOS, SE CALCULAN (607) LAS CARACTERISTICAS ESPECIFICAS DEL LOCUTOR PARA COEFICIENTES DE REFLEXION QUE REPRESENTAN EL MISMO SONIDO Y SE ALMACENAN EN MEMORIA (608,609,610), SE COMPARAN (611) LAS CARACTERISTICAS CALCULADAS DE LOS COEFICIENTES DE REFLEXION REPRESENTANTES DE TAL SONIDO Y ALMACENADAS EN MEMORIA (610) CON LAS SIGUIENTES CARACTERISTICAS DE LOS COEFICIENTES DE REFLEXION QUE REPRESENTAN EL MISMO SONIDO, Y SI, LAS SIGUIENTES CARACTERISTICAS DE LOS COEFICIENTES DE REFLEXION QUE REPRESENTAN EL MISMO SONIDO ESENCIALMENTE NO DIFIEREN DE LAS CARACTERISTICAS DE LOS COEFICIENTES DE REFLEXION ALMACENADAS EN MEMORIA (610), SE CALCULAN (616) Y TRANSMITEN (625) LAS DIFERENCIAS ENTRE LAS CARACTERISTICAS DE LOS COEFICIENTES DE REFLEXION QUE REPRESENTAN EL MISMO SONIDO DEL LOCUTOR Y LAS CARACTERISTICAS DE LOS COEFICIENTES DE REFLEXION CALCULADOS A PARTIR DE LA MUESTRA PREVIA.
