The article touches on this point briefly: > How should one pronounce the cae- in caelum (sky): kai, as it was in Rome of the 1st century BCE, or che, as used in Christian liturgy and modern Italian? but then later concludes when discussing a meeting of students held in Latin: > The meeting removed, however, any concerns I had about sound and style in speaking Latin actively. Differences of pronunciation and expression mattered as little as if I were conversing in English with students from Scotland, Germany or Japan. What mattered was that the language was intelligible, meaningful, accurate and alive. So in short, if people understand you, that's what matters, and the differences can be thought of as differing accents.
