We have a discussion about how to pronounce this Japanese term every time it comes up in an editorial meeting (Pecha Kucha Columbus is a cool event where various presenters explain their ideas and their work by sharing 20 image slides for 20 seconds each). The guys at ThoughtCo directed me to this video that should eliminate all future pronunciation faux pas (although, any way you try to say Pecha Kucha is fun). Just sing the Muppets' Manahmanah song!
