Hey Buck, you're Belgian.
How would you pronounce the full name Mathijs Viaene?
Difficult to explain, it's pretty straightforward for me, but I'm not sure if English speaking people have the needed pronounciations / sounds.
Mathijs: You don't hear the "h". I don't know if you guys have that same "ij" sound, can't really think of a similar sounding English word right now.
Just think of the better known Dutch football player Joris Mathijsen, and stop at the "s"
As for Viaene, you don't hear the first "e", emphasis on the Via part. But it doesn't sound like the via in for example viable. More of a short "i", sounding like "ie".
The "ne" part is short, not sounding like "nee" or "nie". Similar to how the "e" sounds in for example bitter. And unlike in English, you do hear the final "e" after an n sound clearly.
V-IE-AA-ne
Jeez, I hope this makes some sense.
