These are "syllable acronyms", I think; maybe "hi-fi" goes with these.
Something like "radar" is a combination of syllable and letter acronym, I
guess.

Here's another question. Is "Ph.D." an initialism (it's not restricted to
initials)? If the answer is that "ph" is an honorary letter phi or
something like that, then what about "Co.E." (pronounced "see oh ee") =
"computer engineering"? If "Ph.D." is pronounced "fud" (I've heard this
although I think only used frivolously) is it an acronym (narrow sense)?
