Roughly, (t)see-ma-nay or chi-ma-nay. The first sound is an affricate consonant, similar to the sounds spelled ch or j in English (e.g. the final sound of "catch" in General American). The last sound should properly be spelled é, not just e, and is similar to the sound spelled with that letter in French or the sound spelled "ay" in English words like "pray" (also in General American).
