SPGRAMMARSTATE

SPGRAMMARSTATE lists controls for setting and restoring grammar states.

  
    typedef enum SPGRAMMARSTATE
{
    SPGS_ENABLED = 0,
    SPGS_DISABLED = 1,
    SPGS_EXCLUSIVE = 3,
} SPGRAMMARSTATE;

Elements

  • SPGS_ENABLED
    Activates all the top-level rules in the grammar for the SR engine.

    Note that a rule must have an active recognition context, active grammar, and active top-level rule in order to be recognized.

  • SPGS_DISABLED
    Deactivates all the top-level rules in the grammar for the SR engine.

  • SPGS_EXCLUSIVE
    Turns off all top-level rules that are not part of this grammar.

    For example, an application that needs modal-like input exclusivity can change the grammar to exclusive, which disables all other non-exclusive grammars.
