ISpRecoResult::SpeakAudio (Windows CE 5.0)
This method gets and speaks the specified audio. This combines two other methods, first calling ISpRecoResult::GetAudio and then ISpVoice::SpeakStream on the parent recognition context.
If the application did not start retained audio (see ISpRecoContext::SetAudioOptions), or make a previous call to ISpPhrase::Discard and eliminate the retained audio, then this method will fail with SPERR_NO_AUDIO_DATA.
HRESULT SpeakAudio(ULONG ulStartElement,ULONG cElements,DWORD dwFlags, ULONG* pulStreamNumber);
Parameters
- ulStartElement
[in] Element with which to start. - cElements
[in] Number of elements contained in the stream. A value of zero speaks all elements. - dwFlags
[in] Attributes of the text stream. Possible values are defined for the SPEAKFLAGS enumeration. - pulStreamNumber
[out, optional] Pointer to stream number information, or to NULL if no stream number is retrieved.

The following table shows the possible return values. Return values can also be those from ISpVoice::SpeakStream.
