Resumen

En este trabajo se presentan resultados de verificación sobre las cuatro lenguas oficiales españolas: castellano, catalán, euskera y gallego. Se analizan los resultados obtenidos en tests cerrados y abiertos (estos últimos incluyendo segmentos en francés, portugués, alemán o inglés) y considerando segmentos de voz de 30 segundos. Se realiza también un estudio detallado del rendimiento del sistema por cada lengua objetivo. Se usa la base de datos KALAKA creada especialmente para la Evaluación Albayzín 2008 de sistemas de verificación de la lengua. El sistema de verificación principal resulta de la fusión de un sistema acústico y 6 subsistemas fonotácticos. El sistema acústico toma información de las características espectrales de la señal de audio, mientras que los sistemas fonotácticos utilizan secuencias de fonemas producidas por varios decodificadores acústicos. En este trabajo se alcanza una tasa EER= 3,58 % y un coste CLLR = 0.30 en test cerrado, lo que implica una mejora relativa del 24,5 % con respecto a los mejores resultados obtenidos en la evaluación Albayzin 2008 VL.
