Abstract

Se proporciona un reconocedor con valores de probabilidad a priori (por ejemplo, de algun reconocimiento previo) indicando como probablemente varias palabras del vocabulario del reconocedor ocurren en el contexto particular y se cargan las 'clasificaciones' de reconocimiento por estos valores antes de que se elija un resultado (o resultados). El reconocedor también emplea 'un corte', por lo que se desechan los resultados parciales de baja clasificacion, para acelerar el procedimiento de reconocimiento. Para evitar el corte prematuro de las palabras más similares, se aplican valores de probabilidad antes que se hagan las decisiones de corte. También se describe un método para aplicar estos valores de probabilidad.
