Abstract

LA INVENCION SE REFIERE A LA GENERACION DE VOZ SINTETICA Y ESPECIFICAMENTE A LA PRODUCCION DE ONDAS DIGITALES A PARTIR DE UN TEXTO EN FONEMAS. LA INVENCION UTILIZA UNA BASE DE DATOS ENLAZADAS QUE COMPRENDE UN TEXTO EXTENDIDO EN FONEMAS Y SUS EQUIVALENTES EN LA FORMA DE UNA ONDA DIGITAL. LAS DOS PARTES DE LA BASE DE DATOS ESTAN UNIDAS POR UN PARAMETRO QUE ESTABLECE PUNTOS DE EQUIVALENCIA TANTO EL TEXTO DE FONEMAS COMO EN LA ONDA DIGITAL. EL TEXTO DE ENTRADA (EN FONEMAS) SE ANALIZA PARA ENCONTRAR UNA PARTE CONCORDANTE EN LA PARTE DE FONEMAS DE LA BASE DE DATOS. ESTA CONCORDANCIA UTILIZA EQUIVALENCIA EXACTA DE FONEMAS EN DONDE SEA POSIBLE; DE OTRA FORMA SE UTILIZA RELACION ENTRE FONEMAS. EL PROCESO DE SELECCION IDENTIFICA LOS FONEMAS DE ENTRADA EN EL CONTEXTO MEDIANTE LO CUAL SE OBTIENEN CONVERSACIONES MEJORADAS. TENIENDO ANALIZADO EL TEXTO DE ENTRADA EN CADENAS CONCORDANTES EN LA FORMA DE ENTRADA DE LA BASE DE DATOS SE ESTABLECEN LOS PARAMETROS DE PRINCIPIO Y DE FINALIZACION PARA LAS SECCIONES. EL TEXTO DE SALIDA SE PRODUCE JUNTANDO SECCIONES DE ONDA DIGITAL DEFINIDA POR LOS PARAMETROS DE INICIO Y DE FIN.THE INVENTION REFERS TO THE GENERATION OF SYNTHETIC VOICE AND SPECIFICALLY TO THE PRODUCTION OF DIGITAL WAVES FROM A TEXT IN PHONEMAS. THE INVENTION USES A LINKED DATABASE INCLUDING A TEXT EXTENDED IN PHONEMES AND ITS EQUIVALENTS IN THE FORM OF A DIGITAL WAVE. THE TWO PARTS OF THE DATABASE ARE UNITED BY A PARAMETER THAT ESTABLISHES POINTS OF EQUIVALENCE BOTH THE TEXT OF PHONEMES AND THE DIGITAL WAVE. THE INPUT TEXT (IN PHONEMAS) IS ANALYZED TO FIND A MATCHING PART IN THE PHONEMS PART OF THE DATABASE. THIS CONCORDANCE USES EXACT EQUIVALENCE OF PHONEMS WHERE POSSIBLE; OTHERWISE A RELATION BETWEEN PHONEMAS IS USED. THE SELECTION PROCESS IDENTIFIES THE PHONEMES OF ENTRY INTO THE CONTEXT THROUGH WHICH IMPROVED CONVERSATIONS ARE OBTAINED. HAVING ANALYZED THE TEXT OF ENTRY IN CONCORDING CHAINS IN THE FORM OF ENTRY OF THE DATABASE, THE PARAMETERS OF BEGINNING AND ENDING FOR THE SECTIONS ARE ESTABLISHED. THE OUTPUT TEXT IS PRODUCED BY GATHERING DIGITAL WAVE SECTIONS DEFINED BY THE START AND END PARAMETERS.
