ISpRecoGrammar::LoadDictation (Windows Embedded CE 6.0)
1/6/2010
This method loads a dictation topic into the speech recognition grammar object and the SR engine. See also ISpSREngine::OnCreateGrammar.
Syntax
HRESULT LoadDictation(
const WCHAR* pszTopicName,
SPLOADOPTIONS Options
);
Parameters
- pszTopicName
[in, optional] Pointer to the topic name. If NULL, then general dictation is loaded. See Remarks section.
- Options
[in] Value indicating if the file should be loaded dynamically. Possible values are defined for the SPLOADOPTIONS enumeration. This value must be SPLO_STATIC.
Return Value
The following table shows the possible return values.
Value | Description |
---|---|
S_OK |
Function completed successfully. |
E_INVALIDARG |
pszTopicName is invalid or bad. Alternatively, Options is not SPLO_STATIC. |
FAILED(hr) |
Appropriate error message. |
Remarks
SAPI currently defines one specialized dictation topic: SPTOPIC_SPELLING. SR engines are not required to support specialized dictation topic (including spelling).
See the SR engine vendor for information on what specialized dictation topics if any are supported.
Example
The following code snippet illustrates the use of this method.
HRESULT hr = S_OK;
// create a grammar object
hr = cpRecoContext->CreateGrammar(GRAM_ID, &cpRecoGrammar);
// Check hr
// load the general Dictation topic
hr = cpRecoGrammar->LoadDictation(NULL, SPLO_STATIC);
// Check hr
// start the Dictation topic to receive recognitions
hr = cpRecoGrammar->SetDictationState(SPRS_ACTIVE);
// check hr
