Abstract

LA INVENCION HACE RELACION A UN METODO Y UN APARATO PARA EL RECONOCIMIENTO DE VOZ, INCLUYENDO LA VOZ QUE SE VA A RECONOCER UNA O MAS PALABRAS. EL RECONOCIMIENTO ESTA BASADO EN UN ANALISIS DE UNA PRIMERA Y UNA SEGUNDA PRONUNCIACION. DE ACUERDO A LA INVENCION, LA PRIMERA PRONUNCIACION SE COMPARA A UN O MAS MODELOS DE VOZ PARA DETERMINAR UNA SIMILITUD METRICA PARA CADA UNA DE TALES COMPARACIONES. EL MODELO DE VOZ QUE MAS SE ACERQUE A LA PRIMERA PRONUNCIACION SE DETERMINA BASANDOSE EN UNA O MAS SIMILITUDES METRICAS. LA SIMILITUD METRICA QUE CORRESPONDA AL MODELO DE VOZ QUE MAS SE APROXIME SE ANALIZA PARA DETERMINAR SI LA SIMILITUD METRICA SATISFACE UN PRIMER CRITERIO DE RECONOCIMIENTO. LA SEGUNDA PRONUNCIACION SE COMPARA CON UNO O MAS MODELOS DE VOZ ASOCIADOS CON EL MODELO DE VOZ QUE MAS SE APROXIMA (QUE PUEDE INCLUIR EL MODELO DE VOZ QUE MAS SE APROXIMA) PARA DETERMINAR UNA SIMILITUD METRICA DE LA SEGUNDA PRONUNCIACION PARA CADA UNA DE LAS COMPARACIONES. LAS UNA O MAS SIMILITUDES METRICAS DE LA SEGUNDA PRONUNCIACION SE ANALIZAN PARA DETERMINAR SI SATISFACEN UNOS SEGUNDOS CRITERIOS DE COMPARACION. LA SEGUNDA COMPARACION SE RECONOCE COMO LA FRASE QUE CORRESPONDE AL MODELO DE VOZ QUE MAS SE APROXIMA CUANDO ESTAN SATISFECHOS EL PRIMER Y EL SEGUNDO CRITERIOS DE RECONOCIMIENTO. LA PRESENTE INVENCION TIENE SU APLICACION A MUCHOS PROBLEMAS EN EL RECONOCIMIENTO DE VOZ QUE INCLUYEN EL RECONOCIMIENTO DE UNA PALABRA AISLADA Y EL RECONOCIMIENTO DE ORDENES. SE PROPORCIONA UNA FORMACION ILUSTRATIVA DE LA INVENCION EN EL CONTEXTO DE UN TELEFONO CELULAR. TAMBIEN ESTAN DISCUTIDAS OTRAS FORMACIONES.
