Not sure how to pronounce Lisl's name? Try this:
Her first name sounds like "Lee-zil" or "Lee-sil." Either way is fine! (Calling her Lisa, Lyle, or Leslie is not.)
Struggling with "Detlefsen"? Break it into three chunks, and use the Short "E" sound (rhymes with "jet" as in "jetpack!") for each, so Det-lef-sen.
Still need help? Lisl recorded the pronunciation and story of her name over at the excellent TeachingBooks website!
