Can Someone help with text to speech?

Hi there, I found a text to speech talking clock example on here for Construct Classic. I am making a game using Construct Classic and I'm not sure how to use it. I looked at the talking clock example and added the plugin to my objects. I typed the text I wanted it to say but when I run the Game It doesn't work. can someone tell me how to exactly use it?

is there any software like tts engines or something I need to download?

The talking clock example works and I can hear the text but I can't hear the text in my game.

Thanks

Ah I tried that plugin and couldn't figure it out either, but it's probably based off of Microsoft's text to speech system, try looking for Microsoft SAM
