I found a way to get TTS in construct 2 (C2).
The only problem is that it open a new web window lose forus from the game window.
If any one can help, i would very grateful if you can get the web window to open in the background layer so you only hear the sound or some other work around of your own doing.
I would to create TTS as i made spelling game and TTS would help out a lot.
I also aim to share TTS with the rest of C2.
