SAPI Interfaces (Windows Embedded CE 6.0)

1/6/2010

The following table shows the Speech API (SAPI) interfaces with a description of the purpose of each.

Programming element	Description
_ISpPrivateEngineCall	This interface enables private calls to a speech recognition (SR) engine.
IEnumSpObjectTokens	This interface enumerates speech object tokens.
ISpAudio	This interface represents a real-time audio stream, such as those connected to a live microphone or telephone line.
ISpCFGInterpreter	This interface interprets a context-free grammar (CFG).
ISpCFGInterpreterSite	This interface sets properties and text replacements in a phrase.
ISpContainerLexicon	This interface defines a container lexicon that automatically loads the user lexicon and all available application lexicons when created.
ISpDataKey	This interface provides a mechanism for storing and retrieving string and other data.
ISpErrorLog	This interface prepares a log file of compilation error messages.
ISpEventSink	This interface allows event sources to send events directly to an event sink through a free-threaded call.
ISpEventSource	This interface provides the mechanism to filter and queue events.
ISpGramCompBackend	This interface represents the grammar compiler back end that works with a binary grammar.
ISpGrammarBuilder	This interface exposes the back end of the SAPI context-free grammar (CFG) compiler.
ISpGrammarCompiler	This interface represents the SAPI 5.0 text grammar compiler.
ISpITNProcessor	This interface performs inverse text normalization (ITN) for an ITN grammar.
ISpLexicon	This interface is used to access lexicons, which contain information about words that can be recognized or spoken.
ISpMMSysAudio	This interface represents the audio implementation for the standard Windows multimedia layer (wave in and wave out).
ISpNotifyCallback	This interface allows the application to receive notifications.
ISpNotifySink	This interface specifies an event sink to receive notifications.
ISpNotifySource	This interface allows the application to configure the events that trigger notifications.
ISpNotifyTranslator	This interface converts a call to the ISpNotifySink::Notify method into the appropriate notification.
ISpObjectTokenCategory	This interface defines an object token category
ISpObjectTokenEnumBuilder	This interface maintains an object token enumerator (ISpObjectToken).
ISpObjectTokenInit	This interface initializes an object token to use a data key.
ISpObjectToken	This interface handles object token entries.
ISpObjectWithToken	This interface represents any object that is associated with an object token.
ISpPhoneConverter	This interface enables the client to convert from the SAPI character phone set to the identifier phone set.
ISpPhraseAlt	This interface enables applications to retrieve alternate phrase information from an SR engine.
ISpPhraseBuilder	This interface builds a phrase from the provided elements.
ISpPhrase	This interface accesses information contained in a phrase.
ISpRecoContext	This interface enables applications to create different functional views or contexts of the SR engine.
ISpRecognizer	This interface enables applications to control aspects of an SR engine and its audio input.
ISpRecoGrammar	This interface enables applications to manage the words and phrases that the SR engine will recognize.
ISpRecoResult	This interface enables applications to retrieve information about hypotheses, recognitions, and false recognitions of the SR engine.
ISpRegDataKey	This interface creates a new data key using a specific key in the registry for storage.
ISpResourceManager	This interface provides access to resources shared by different speech components in the same process.
ISpSRAlternates	This interface allows alternate word selection and implementation for speech recognition.
ISpSREngineSite	This interface gets audio data, retrieves grammar information, sends events, and returns recognition information to SAPI.
ISpSREngine	This interface defines an SR engine.
ISpStreamFormatConverter	This interface is the primary interface implemented by the SAPI audio data format converter.
ISpStreamFormat	This interface is the minimum extra interface required by SAPI on top of the IStream interface.
ISpStream	This interface provides two distinct pieces of functionality: It allows the application to wrap up an existing stream by providing both an IStream and its format so that the underlying ISpStreamFormat object can provide this data to SAPI when required. It allows the creation of an object suitable for SAPI use from a file using the BindToFile method.
ISpTaskManager	This interface implements a task management service provider to optimize thread use.
ISpTask	This interface is a C++ pure virtual interface, and not a COM interface. It is used by objects that want to perform atomic operations that are optimized for a multiprocessor computer.
ISpThreadControl	This interface controls a thread.
ISpThreadTask	This interface supports initializing and processing of an allocated thread, and is used to simplify thread-based operations.
ISpTokenUI	This interface provides programmatic management of a UI associated with an object implementing ISpObjectToken.
ISpTranscript	This interface represents the transcript for wave audio files supported by the SAPI SpStream object.
ISpTTSEngineSite	This interface writes audio data and queues events for the TTS engine.
ISpTTSEngine	This interface defines the SAPI 5.0 text-to-speech (TTS) engine, a driver that is used for speech synthesis.
ISpVoice	This interface enables an application to perform text synthesis operations.
