The closest English approximation is: San-tegz-oo-pay-ree

If you want to get closer to the authentic French flair, follow these steps:

Saint: This isn't like the English "Saint." Think of a soft "San" (like the beginning of sandwich), but keep it nasal and short.

Exu: The "x" sounds like a "gz". The "u" is the hardest part; it’s a tight sound made by rounding your lips like you're going to whistle but saying "ee."

péry: This is straightforward: "pay-ree." Make sure to keep the "r" soft, not a hard American "r."
