I'm from Pennsylvania in the United States.We pronounce it /toot/ (like instiTUTE)- like it was an onomatopoeia of a whistle noise.
Ya'know, if we just dropped the "i" and made it "tute", I think that people would actually pronounce it correctly more often than not.
Tell me if you have noticed the "Tuite pucker" too.Someone is about to try to pronouce "Tuite" and they can't seem to get past the first "T" and they have this puckered look on their face from the pronounciation of the "T".
Also - there is nothing like experiencing for the thousandth time someone being amused with themself for their amazing creativity and ingenuity in making the whistle noise "toot toot" in your presence.
Actually I think that I got the best mispronounciation of the "Tuite" name of all.An english teacher of mine in the 9th grade once pronounced it as "t w a t". (The genealogy.com submission program didn't allow me to write it out the first time.)
I can't help but asking about some other pronounciations - where are you getting the "ch" sound from? Nothing suprises me anymore about the pronounciation of the weird collection of vowels but the "t"s always seemed pretty standard to me.
I'm glad that I bought the tuite.com domain name when I did.There's more Tuites on the internet all the time. It's cool having my email address as email@example.com (note - I didn't write out my actual email address since spam web crawlers would pick it up.)
Another side note - "tuite" is also a word that refers to an asian martial art.(You'll find it all over search engines)
