ABSTRACT:
A vocabulary sub-set is selected from a large speech recognition dictionary. The selected vocabulary sub-set may be used in a real time directory assistance system to improve the system's real-time performance. The selection process is effected on the basis of the cost-benefit ratio, the benefit being measured in savings in operator working time. On the other hand, the cost is measured in terms of hardware limitations, namely processor throughput. Typically, the vocabulary sub-set is limited to a maximum number orthographies that would enable the system to achieve real-time performance.
