Young, SJ and Russell, NH and Thornton, JHS (1991) Use of syntax and multiple alternatives in the VODIS voice operated database inquiry system. Computer Speech and Language, 5. pp. 65-80. ISSN 0885-2308Full text not available from this repository.
The paper describes the architecture of VODIS, a voice operated database inquiry system, and presents some experiments which investigate the effects on performance of varying the level of a priori syntactic constraints. The VODIS system includes a novel mechanism for incorporating context-free grammatical constraints directly into the word recognition algorithm. This allows the degree of a priori constraint to be smoothly varied and provides for the controlled generation of multiple alternatives. The results show that when the spoken input deviates from the predefined task grammar, a combination of weak a priori syntax rules in conjunction with full a posteriori parsing on a lattice of alternative word matches provides the most robust recognition performance.
