The recognizer can continue to propose hypotheses until one successfully parses , or until a quitting criterion is reached , such as an upper bound on N. Whereas in the loosely coupled system the parser acts as a filter only on completed candidate solutions ( Zue et al. 1991 ) , the tightly coupled system allows the parser to discard partial theories that have no way of continuing . Following the Viterbi search , each partial theory is first extended by the parser to specify possible next words , which are then scored by the recognizer .
