SPFEI
SPFEI casts a specified value into a 64-bit type.
For a list of the supported SPEI_ord event types, see SPEVENTENUM
Found in: sapi.idl
<pre IsFakePre="true" xmlns="http://www.w3.org/1999/xhtml"> <strong>SPFEI(</strong> <strong> void</strong> *<em>SPEI_ord</em> <strong>);</strong> </pre>
Parameters
- SPEI_ord
[in, out] The value to re-cast. The new value is passed back.
Return Values
Related Helper Macros
| Macro | Description |
|---|---|
| SPFEI_FLAGCHECK | Retrieves reserved flags for the event interest enum. |
| SPEI_ALL_EVENTS | Retrieves all possible events flags. |
| SPFEI_ALL_TTS_EVENTS | Retrieves all possible text-to-speech (TTS) event flags. |
| SPFEI_ALL_SR_EVENTS | Retrieves all possible speech recognition (SR) event flags. |
Remarks
The SPFEI_FLAGCHECK macro retrieves the flags that must always be included in any event interest. The Speech Platform uses the SPFEI_FLAGCHECK macro to help developers avoid mistakes by using event interest related methods (see ISpEventSource::SetInterest and ISpRecoContext::SetVoicePurgeEvent) with the actual enumeration instead of the SPFEI() macro.
Example
Here is an example of the SPFEI macro used to set event interest for speech recognition (SR):
<pre IsFakePre="true" xmlns="http://www.w3.org/1999/xhtml"> hr = g_cpRecoCtxt->SetInterest(SPFEI(SPEI_RECOGNITION), SPFEI(SPEI_RECOGNITION)); </pre>
Here is an example of the SPFEI_ALL_SR_EVENTS macro used to set SR event interest in all events. Note this is an example and not recommended practice.
<pre IsFakePre="true" xmlns="http://www.w3.org/1999/xhtml"> hr = g_cpRecoCtxt->SetInterest(SPFEI_ALL_SR_EVENTS, SPFEI_ALL_SR_EVENTS); </pre>
