Using the SAPI object in Inno Setup

Question

I want to use the Windows SAPI COM object to make a sound during installation. I know that in VBScript they do it like this:

Set oVoice = CreateObject("SAPI.SpVoice")
set oSpFileStream = CreateObject("SAPI.SpFileStream")
oSpFileStream.Open "xxx.wav"
oVoice.SpeakStream oSpFileStream
oSpFileStream.Close

I asked, how to do this in an Inno Setup script. I'm pretty new to Inno Setup, and still have not learned how to use the CreateOleObject function and so on. I tried to understand the Inno Setup documentation and it did not help me. Other answers about using COM objects also did not make me understand this. Thanks for your help

Use CreateOleObject support function:

var
  oVoice, oSpFileStream: Variant;
begin
  oVoice := CreateOleObject('SAPI.SpVoice');
  oSpFileStream := CreateOleObject('SAPI.SpFileStream');
  oSpFileStream.Open('xxx.wav');
  oVoice.SpeakStream(oSpFileStream);
end;

See Pascal Scripting: Using COM Automation objects.

For alternate solution, see Playing sound during an Inno Setup install.
