Well in my opinnion their spanish isnt that bad. At least they try to say the stuff the best they can. I bet you might have problems with some Hindi or some Malay last name with 30 vowels and 15 consonants all together. I bet a mislip letter pronunciation wont help at all

The only complain i have is that in versus.com they said that BAHAMONTES was 80 years old? well the last name is BAHAMONDES!!!!! What I think is that they mispelled it because a D in spanish and a T in english tend to sound similar when spelling stuff with a spanish accent.

TOMATO - TOMATOES

At least they try and are worried somehow of how to pronunciate last names and names correctly, I give them credit for that. Regarding your mislip rule thing... is all i can say about it una CE es una CE allá, aquí y en la quebrada del ají!

Thanks
