Finally someone ! Yes, you are right saying that nobody gives the answer to a question regarding this specific thread. And this specific part of the forum, named iGO, not Vocalizer etc.
In the past the iGO I installed was working with any svox language I had installed, keeping the same logic : you install Virginie, Thomas etc in Svox, you put a similar TTS language in iGO and the program speaks on the tts installed in device, not iGO. And you put a same language Audio folder in iGO's root and voilá you have voice alerts too !
Now, trying the same, folowing this guide, you get nothing but a phone who "speaks" in any language you install and iGO that at TTS is greyed out.
And to be more specific. The only voice files I am seeing in iGO are the normal voices, the tts are not visible .Others are saying that they can select tts voices, me I can't.
And what about the other folders in tts languages like v5auto.dll ? Do you need the folder and .dll ?
Anyway thanks for the help, I will try also with the file you kindly offered.
