Accessing Microsoft SAPI 5.4

[kww]

I'm not sure if this is the right forum to ask in, so please point me at another one if it would be more productive. I'm working on an application involving speech synthesis on the server, and I would like to access Microsoft's SAPI 5.4 (http://msdn.microsoft.com/en-us/library/ee125077%28v=VS.85%29.aspx) directly from PHP code, or through a small wrapper of Javascript/Visual Basic if necessary. Can anyone point me in the right direction to get started? The application would be running on Windows 7 64-bit, using PHP 5.3. This application would be running as an independent task so it shouldn't get directly involved with the web server, but that's Apache2.2 if there's some reason that it is important.

<?php

$TTS = new COM("SAPI.SpVoice");

$TTS->Speak('Hello world!');

?>

 

seems to work.
