Microsoft Speech Platform

ISpProperties::SetPropertyNum

ISpProperties::SetPropertyNum sets a numeric property corresponding to the specified name.

<pre IsFakePre="true" xmlns="http://www.w3.org/1999/xhtml"> <strong>HRESULT SetPropertyNum(</strong> <strong>LPCWSTR</strong> *<em>pName</em>, <strong>LONG</strong> <em>lValue</em> <strong> );</strong> </pre>

Parameters

  • pName
    [in] Null-terminated string containing the property name. See Modify Speech Recognition Engine Properties for valid values.
  • lValue
    [in] The property value to set.

Return Values

Value Description
S_OK Function completed successfully.
S_FALSE The speech recognition engine does not support the specified property name.
E_INVALIDARG One or more parameters are invalid.
FAILED(hr) The speech recognition engine returned a specific error.

Remarks

If the speech recognition engine supports the property, the Speech Platform will fire a property-changed event (see SPEI_PROPERTY_NUM_CHANGE) to all interested recognizer contexts (ISpRecoContext). Broadcasting the corresponding event notifies any recognizer contexts that had interests in the property (see CSpEvent::PropertyName and CSpEvent::PropertyNumValue).
