ISpSREngineSite

Other versions of this page are also available for the following:

• Windows Embedded CE 6.0 R3

8/28/2008

This interface gets audio data, retrieves grammar information, sends events, and returns recognition information to SAPI. It is implemented by SAPI and is called by an SR engine. After SAPI creates the SR engine, the engine obtains a pointer to ISpSREngineSite when the ISpSREngine::SetSite is called.

When to Implement

Only SAPI implements this interface.

Methods

The following table shows the methods for the ISpSREngineSite interface.

Method	Description
AddEvent	Adds an event to the SR engine site.
DataAvailable	Gets the amount of data that can be read without blocking.
GetContextMaxAlternates	Gets the maximum number of alternates that should be generated for the specified recognition context.
GetMaxAlternates	Gets the maximum number of alternates that should be generated for the specified rule.
GetResource	Gets a named resource from a grammar.
GetRuleInfo	Gets information about a CFG rule.
GetStateInfo	Gets information on the transitions from a CFG state.
GetTransitionProperty	Gets property information for a transition in a grammar.
GetWordInfo	Gets information about a CFG word.
IsAlternate	Determines whether one rule is a valid alternate of another.
ParseFromTransitions	Produces a phrase builder result from a list of transitions.
Read	Reads audio data from the input stream.
Recognition	Retrieves a recognition result (final, partial, or false) for SAPI.
SetBufferNotifySize	Sets the amount of data to be available before data available event is set.
SetRuleClientContext	Sets client context on a CFG rule.
SetWordClientContext	Sets a client context on a CFG word.
Synchronize	Informs SAPI that the engine is ready to process changes in its grammars.
UpdateRecoPos	Updates the current position of the recognizer in the stream.
