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.
