Abstract
UNA UNIDAD DE CODIFICADO (2) DIVIDE LAS SEÑALES DE VOZ ENTRANTES POR UN TERMINAL DE ENTRADA (10) EN UNIDADES, SEGUN SU CONFIGURACION Y CODIFICA LAS SEÑALES DIVIDIDAS EN BASE A PARAMETROS DE CODIFICACION DE SALIDA TALES COMO LOS PARAMETROS DEL PAR DE LINEAS ESPECTRALES (LSP), EL TIMBRE, AMPLITUD AM ESPECTRAL, SONORA (V) O SORDA (UV). LA UNIDAD (3) DE CODIFICADO DE PARAMETROS MODIFICADOS INTERPOLA LOS PARAMETROS DE CODIFICADO PARA CALCULAR LOS PARAMETROS DE CODIFICADO MODIFICADOS ASOCIADOS CON LOS PUNTOS TEMPORALES DESEADOS. UNA UNIDAD DE DECODIFICADO (6) SINTETIZA LAS ONDAS SINUSOIDALES Y EL RUIDO EN BASE A LOS PARAMETROS DE CODIFICADO MODIFICADOS Y GENERA LAS SEÑALES DE VOZ SINTETIZADAS EN UN TERMINAL DE SALIDA (37). EL CONTROL DE VELOCIDAD PUEDE REALIZARSE FACILMENTE CON UNA TASA ARBITRARIA SOBRE UN ANCHO RANGO CON ALTA CALIDAD DE SONIDO, SIN QUE CAMBIEN EL FONEMA NI EL TIMBRE.
