Mina (also commonly known as Gen) is a language spoken in Togo and the Mono department of Benin. Mina remains little studied in comparison to the related language Ewe. The present study attempts to shed light on Mina phonetics. In particular, the question whether Mina voiced coronal stops form a single category or two categories distinguished by retroflexion is investigated through acoustic, articulatory, and perceptual analyses.
