kon-SAN-gwin-ee-uhs
Here's a breakdown:
* kon: Like the beginning of "con" in "concert"
* SAN: Like the word "san" in "sand"
* gwin: Like "win" in "winner"
* ee: Like the "ee" in "see"
* uhs: Like the "us" in "bus"
It's important to emphasize the first syllable ("kon") and make the "g" sound like a "j" in "gem."
