The second vowel is an unstressed “i”. In most varieties of English, since it is unstressed, we pronounce it as a schwa, which sounds roughly like “uh”.
If you’d like to articulate that syllable, like you might do in French, then pronounce it like the “i” in “sit”. That’s completely optional.
Our naming convention was comic strip characters, hence Hobbes, Casper, and Quincy.
