如何處理SAPI引擎中的暫停事件

Question

我目前已經實施了SAPI語音，它工作正常。我想知道當應用程序調用ISpVoice-> Pause時，如何處理引擎中的Pause事件。

Answer 1

據我所知，ISpVoice::Pause完全在SAPI層中實現，並且不進行任何引擎調用。

Answer 2

我試圖準確理解你的最終目標是什麼，但我認爲我會採取一個答案來回答這個問題。

對於聲音，暫停執行以下操作根據MSDN：

ISpVoice ::暫停在最近的警報界限暫停語音和關閉輸出設備，允許未決的發言從其他聲音請求訪問。

假設您已經使用SPF_AYSNC的講電話，你可能還需要還成立事件的興趣和警報界限所看到here

凡例子顯示處理書籤警報界限

'Create a Normal Priority voice - male 
Set objHIM = New SpVoice 
Set objHIM.Voice = objHIM.GetVoices("gender=male").Item(0) 

objHER.Speak "the priority of this voice is S V P alert" 
objHIM.Speak "the priority of this voice is S V P normal" 

objHIM.EventInterests = SVEBookmark  'Receive bookmark events only 
objHIM.AlertBoundary = SVEPhoneme  'Let alert voices interrupt words 

'Normal voice speaks text which generates events. 

strSpeak = "This is text that contains bookmarks " _ 
      & "for the purpose of generating events." 

objHIM.Speak strSpeak, SVSFIsXML + SVSFlagsAsync
