Using microsoft TTS in youtube videos ??? What you think !

hi,

I recorded samples of Microsoft Hazel (Windows 8's built in speech synth) to use in a youtube video to be the "narattor". just .wav file samples of the voice
I just wanted to know, I am allowed to use Microsoft Hazel in this way? Is it okay to use Microsoft Speech recording samples in monetized videos?
have you ever see a video in youtube using this method ? ads shown ??
I think I am safe to use the recordings but I want to be sure so I don't have legal problems down the road.

thank you !

between us . if the voice is copyrighted , how long i can cheat before they catch me

Microsoft being microsoft..........they would probably frown upon it.

But to be honest i have no idea

I don't think you would get into trouble, but if you want to make
sure, contact Microsoft and ask them. If they say it is forbidden,
try some of the online TTS demos. Sitepal has some decent voices,
but you need an aplication that records "what you hear" through
your PC. The freeware application, Audacity will do it.
