Running SAPI.SpVoice with HTA or WSH

Chaps,

After several hours of googling and testing i have got a very simple text to voice javascript command to work.

Code:

<script language="javascript" type="text/javascript">
        var VoiceObj = new ActiveXObject("SAPI.SpVoice");
        VoiceObj.Speak("Voice Test");
    </script>

The issue i have is when i run it with no IE security changes i get "Automation server can not create object".

By further investigation i have found by enabling "Initialize and script ActiveX controls not marked as safe for scripting" in custom security settings / IE the script works fine.

I have found a non p2p forum posting which indicated that the scripting environment should be either HTA or WSH to combat the issue but have not found any working examples.

Has anyone got a better understanding of the two environments where SAPI.SpVoice has been integrated correctly.

Thanks

Well you can either have a standalone script with a js extension that just contains the code you posted, no script tags, or you can rename your html page to be hta and then it becomes a scripted exe.
You can search for HTA on msdn.com for examples. Basically speech capabilities are quite dangerous, there are examples of people with speech recognition software running that have had files deleted by scripts that have spoken commands so unless your web app is running on a corporate intranet and you can make it a trusted site it's not suitable for general web use.
