TFE, I am regularly astounded at how few people can use a search engine. In less than a minute I found a webpage suggesting that if you're looking for the SAPI 5.3 API you should search MSDN (which would have been a logical starting point). One more search revealed this webpage <http://blogs.msdn.com/chuckop/archive/2006/11/24/microsoft-speech-api-s dk.aspx> which explains that the SAPI 5.3 API has been integrated into the Windows SDK. The author also states the following:
"For the SDK, you can download the SAPI 5.1 SDK to create applications and engines that work on Windows XP and Windows Server 2003. These applications or engines should also be forward-compatible with SAPI 5.3 on Windows Vista and beyond. The SAPI 5.1 SDK is a stand-alone package, separate from other Microsoft SDK's." Reading between the lines, you're probably not going to be able to use SAPI 5.3 on Windows XP because it is not supported. In all likelihood, if you want to use SAP 5.3 you will need to upgrade to Windows Vista or later. However, if I were you I would invest a little more time exploring the SAPI 5.1 API documentation <http://www.nextup.com/sapi5doc/Getting_Started.htm>. As far as I can see, the ISpVoice interface <http://www.nextup.com/sapi5doc/ISpVoice.htm> for 5.1 does support WaitUntilDone as well as SpeakCompleteEvent (the former blocks while the latter allows you to hook an event). I hope the above helps.

That's a very good link. I have tried a few inbuilt callbacks like isSpeaking. So far still unable to get it to work as it should. May be it is because I am doing it within the VCL thread and that too within a for loop. Although I dont know why that should matter. I have heard that SAPI 5.3 has a new function WaitUntilDone that I think would be so useful. However how to get the download of it. Unlike previous versions, this is part of platform SDKs. I am using Windows XP SP3. Regards TFE http://totallyfreeenergy.zxq.net
