Field Detail

GARBAGE

public static final RuleSpecial GARBAGE

Special GARBAGE RuleComponent that may match any speech up until the next RuleComponent match, the next token, or until the end of spoken input.

A RuleGrammar processor must accept RuleGrammars that contain GARBAGE. However, the behavior of GARBAGE is implementation-specific. A user agent should be capable of matching arbitrary spoken input up to the next token, but may treat GARBAGE as equivalent to NULL (match no spoken input).
