Using AI speech in missions.

Hi all - I'm new here!

I'm looking for a way to use the default AI voices in my missions as speech. I know how to create conversations using .ogg files from recordings of people or from text to speech programs - however I find it disrupts my mission when the characters start talking in the default Arma 2 voices during combat etc.

Is there a way of making dialogue by using the ai voices? And if so, how would I go about this?

I'm sorry if this has been answered before, but most of my searches revealed only how to include recorded human/TTS voices in a mission. Any help would be greatly appreciated!
