Abstract :
This paper reports on the design, development and evaluation of a bilingual telephone-based spoken language system for foreign exchange inquiries-the CU FOREX system. The telephone-based system supports Cantonese and English in a single spoken language interface to access real-time foreign exchange information. The specific domain covers information on the exchange rates between foreign currencies, as well as deposit interest rates of various time durations for a specified currency. Overall our system achieves a performance of 0.95 (kappa-statistic), with a typical transaction duration of 2 minutes on average
