Speak notifications language, dude 6.43.16

Hi guys , im trying to set some speak notifications.
I noticed that speak notification reads with english accent my text , wich is in spanish so it sound very weird.
Is it some way to change this behaviour ?
Regards.

I think this is your Windows setting, not in Dude

Dear normis,
Thanks for your comment.
Im using windows 7 with spanish languaje.
My dude client uses english languajes, there is no way to change it , and there is not other languaje version. (I didnt find any).

What do you suggest ?
Thanks,
Leandro.
