On the many definitions of
"speak"
Kimi mumbles
incomprehensibly even in Finnish though. But he has the distinct "Finnish accent" there.
It depends a lot of your teacher when you are young what "twang" you get. or if you end up somewhere as an exchange student. But it depends, here for example is
this "Lordi" interview. The interviewer is Finnish, and Mr.Lordi is Finnish... a few "distinct" things there but you need to know what to listen for... s, sh, ch, th, w... all the "weird sounds" for Finns.
Now people that use the language a lot like
Ville Valo doesn't have any distinct "Finnish twang" there.
And then you have the classic
rally driver speak
Which is then not as bad as
politician speech, that can be tankeros...
