How is ESPRIT pronounced?
ESPRIT, like the French word.

For two reasons:


Out of vanity of myself, I learned it like that, I used it in presentations like that, and all I need for that to be correct is for a majority to recognize it to be correct. Hence, by stating this publicly, I make it correct! (just kidding, but when you look at language, there's no right or wrong – there's only conventions)
A. Paulraj himself pronounces it French in this presentation, and he should know :)


So, I disagree with @Envidia on how it's pronounced, but I agree with them on: It doesn't really matter.
