accept_check [-t] [-s spname] [-v] {prefix}

DESCRIPTION

accept_check is a tool to check whether a sentence can be accepted or rejected on a grammar (prefix.dfa and prefix.dict). The sentence should be given from standard input. You can do a batch check by preparing all test sentence at each line of a text file, and give it as standard input of accept_check.

This tool needs .dfa, .dict and .term files. You should convert a written grammar file to generate them by mkdfa.pl.

A sentence should be given as space-separated word sequence. It may be required to add head / tail silence word like sil, depending on your grammar. And should not contain a short-pause word.

When a word belongs to various category in a grammar, accept_check will check all the possible sentence patterns, and accept it if any of those is acceptable.
