Abstract

UN APARATO DE RECONOCIMIENTO DE LA PALABRA HABLADA DE ACUERDO A LA PRESENTE INVENCION INCLUYE UNA PORCION (5) DE CALCULO DE VECTOR MEDIO, UNA PORCION (6) DE COMPENSACION, Y UNA PORCION (8) DE EMPAREJAMIENTO. LA PORCION (5) DE CALCULO DE VECTOR MEDIO CALCULA UN VECTOR MEDIO PARA CADA UNA DE LAS REGIONES DE RUIDO Y LAS REGIONES DE HABLA DEL DISCURSO DE ENTRADA Y UN MODELO DE REFERENCIA RECIBIDO DESDE UNA PORCION (4) DE CONVERSION DE ESPECTRO QUE CORRESPONDE A INFORMACION EMPAREJADA RECIBIDA DESDE UNA PORCION (2) PRELIMINARMENTE EMPAREJADA. LA PORCION (6) DE COMPENSACION COMPENSA LOS VECTORES MEDIOS CALCULADOS POR LA PORCION (5) DE CALCULO DE VECTOR MEDIO PARA AL MENOS UNA DE LAS SECUENCIAS DEL ESPECTRO DEL DISCURSO DE ENTRADA Y LA SECUENCIA DE TIEMPO DEL ESPECTRO DEL MODELO DE REFERENCIA DE MODO QUE EL VECTOR MEDIO DE LA SECUENCIA DE TIEMPO DEL ESPECTRO DE LA REGION DE RUIDO DEL HABLA DE ENTRADA SE ADAPTA CON EL VECTOR MEDIO DE LA SECUENCIA DE TIEMPO DEL ESPECTRO DE LA REGION DE RUIDO DEL MODELO DE REFERENCIA Y QUE EL VECTOR MEDIO DE LA SECUENCIA DE TIEMPO DEL ESPECTRO DE LA REGION DE HABLA DE ENTRADA ENCAJA CON EL VECTOR MEDIO DE LA SECUENCIA DE TIEMPO DEL ESPECTRO DE LA REGION DE HABLA DEL MODELO DE REFERENCIA. LA PORCION (8) DE EMPAREJAMIENTO FINALMENTE EMPAREJA EL MODELO DE REFERENCIA CON EL DISCURSO DE ENTRADA Y PRODUCE UN RESULTADO DE RECONOCIMIENTO. PUESTO QUE RUIDO ADICIONAL Y CONDICIONES DE RUIDO DE L A DISTORSION DEL CANAL DEL DISCURSO DE ENTRADA A SER RECONOCIDA SON RAPIDAMENTE EMPAREJADOS CON LOS DE UN MODELO DE REFERENCIA, INCLUSO SI EL RUIDO ADICIONAL Y MICROFONO Y CANAL DE TRANSMISION A TRAVES DE LOS CUALES ES CAPTADO EL DISCURSO DE ENTRADA SON DESCONOCIDOS, CUANDO LA PALABRA HABLADA DE ENTRADA ES PREPARADA Y EL RUIDO AÑADIDO Y LAS CONDICIONES DE RUIDO VARIAN PARA CADA DISCURSO DE ENTRADA, EL APARATO DE RECONOCIMIENTO DE VOZ PUEDE RECONOCER PRECISAMENTE VOZ NO INFLUIDA POR RUIDO AMBIENTAL. POR ELLO, EL APARATO DE ACUERDO A LA PRESENTE INVENCION PUEDE RESOLVER LOSINCONVENIENTES QUE LOS APARATOS CONVENCIONALES HAN TENIDO.
