This is a most excellent place for technology news and articles.
Actually, I just checked my voice assistant, it got CZM from “see-zed-em” just fine. American English settings on my phone with a PNW grey accent. In fact, saying “see-zee-em” failed more for me, thinking I said CCM or Cesium multiple times.
That’s what they were saying. We know OP doesn’t say zed because you’d expect to get “CZM” saying it that way. We know OP says zee because the dictation mistakenly typed CZM instead of the desired Cesium - the atom used in atomic clocks.
