* Wel: The "w" sound is similar to the English "w" in "wet."
* tje: This part is a little tricky. The "t" is pronounced with a slight aspiration, almost like a "th" in "thin" but less pronounced. The "je" is pronounced like the "y" in "yes."
So, the full pronunciation is something like: "velt-yuh"
Important Note: The "e" at the end is a very short, almost silent vowel. The emphasis is on the first syllable ("wel").
